Thank you for purchasing Heat-On
Please read this Instruction Manual thoroughly before operating your unit.
Introduction
eat-On is a modular heating and stirring work station designed to accept either one or two round bottom flasks from 10ml to 5 litres.
The optional PTFE Safety Covers are designed to compliment and enhance the performance and safety of eat-On blocks.
eat-On offers the following features and benefits:
• All eat-On blocks are manufactured from solid aluminium providing excellent, even heat transfer to the
entire block, preventing hot spots
• Sleek weight saving design reduces the mass of the block to be heated, improving heat-up times
• Uniquely shaped deep wells maximise heated surface area to improve heat-up time and minimise the difference
between the block and solution temperature
• Fluoropolymer coating gives added durability
• Tests have shown that a 250ml flask of water can be boiled in under 9 minutes, 50% faster than the competition
• All eat-On blocks have a probe hole for use with separate temperature probe
• eat-On blocks can be used up to 200˚C without damage to the block. Temperatures up to 260˚C can be achieved
but some minor surface degradation may occur.
PTFE Safety Covers
These innovative, solid PTFE Safety Covers reduce the risk of users touching the ‘hot’ eat-On block and provide the
added benefit of lowering energy consumption...
• PTFE insulation reduces the temperature of contact surface areas by up to 50% and provides a thermal
safety barrier to the operator when working at elevated temperatures.
• PTFE insulation reduces energy consumption required to heat the eat-On Block by up to 15%
• PTFE covers hot metal surfaces and helps prevent accidental spills of solvents on to ho t surfaces
• Chemically resistant PTFE withstands temperatures up to 260˚C
• Fits easily over existing eat-On Blocks
• All eat-On Safety Covers have a probe hole for use with separate temperature probes

The following symbols are intended to assist the user in the safe and efficient operation of eat-On.
Important WARNINGS
1. Please read these instructions completely before using your Heat-On Block.
eat-On should only be operated by trained and competent personnel. As with all chemistries, a full risk assessment should be
performed prior to starting, and care should be taken to monitor your reactions at all stages. During operation eat-On should not
be left unattended unless in a supervised area.
2. Operate only in a fume cupboard with protective safety sash.
3. During and after heating take care not to touch the Heat-On block.
4. Risk of burns from hot blocks
Like oil baths, eat-On blocks remain hot for some considerable time after the heating source has been switched off. A temperature
probe or temperature sensitive label can be used to indicate when blocks are too hot to touch. The use of eat-On PTFE Safety
Covers will also reduce the risk of users touching the ‘hot’ block.
5. Flask selection process
eat-On is designed so that over sized flasks cannot fit through the slightly narrower opening at the top of the block well. This means
that all suitable flasks should sit at the bottom of the block well, be a loose fit and as such spin freely in the eat-On well.
When a flask is inserted into the well it is important to ensure that the flask touches the bottom of the well and does not ‘catch or stick’
on the sides of the block well. If the flask is ‘catching or sticking’ it may be deformed and may result in jamming and even cracking of
the flask when the eat-On block is cooling.
There is a simple rule when using glassware with the eat-on: “If it does not spin, then throw it in the bin”. If the flask does not
spin freely then it is unsuitable for use in the eat-On and an alternative flask should be used.
During the design of eat-On, Radleys have evaluated and tested flasks from a wide range of glass manufacturers to ensure that
eat-On blocks will accept the widest possible range of sizes and styles. owever, because the tolerances on mass produced glass-
ware can vary greatly it is not possible to guarantee that all brands will fit. Indeed, experience shows us that glassware from a single
manufacturer may vary considerably in size and shape from batch-to-batch and also from item-to-item. In such circumstances cus-
tomers may have to pre-select appropriate sized glassware to use with eat-On.

6. Starting and stopping your reaction
In an ideal situation you should load your glassware into the block when the block is at ambient (room temperature).
owever in certain situations this may not be practical. In such circumstances you should note:-
a. You can use cold water to cool the block down rapidly, but take care with blocks above 100˚C as steam is a potential hazard.
b. It is generally safe to insert flasks into blocks that are below 50˚C, but the flask should be removed before the block temperature
drops below the start temperature as there is a small risk that the contraction of the block could crush the glass flask.
c. In all eventualities flasks should be removed at or above the temperature they were originally inserted; i.e. in the case of a flask
that is inserted at 80˚C, it should be removed when or before the block cools to 80˚C.
7. Chemical resistance
Anodised eat-On blocks are resistant to the majority of solvents and splash resistant to dilute acids and alkalis at room temperature.
The fluoropolymer coated eat-On blocks offer superior resistant to the majority of solvents, acids and alkalis.
Extended exposure to acids or alkalis will attack the surface of the eat-On blocks. The stronger the concentration and the longer the
exposure time the more chance and intensity of any attack. eat will also speed up and intensify any attack. e.g. hot concentrated
sulphuric acid will damage the fluoropolymer coated eat-On blocks over a period of time. It is important to clean off any residual
chemical spills immediately after they occur.
8. Temperature range
eat-On blocks can be used up to 200˚C without damage to the block. Temperatures up to 260˚C can be achieved but some minor
surface degradation may occur.
9. Use of the Optional PTFE Safety Covers
•The eat-On Safety Cover is designed to be used in conjunction with eat-On blocks.
Please ensure that you have read the eat-On instructions fully before using the
eat-On Safety Covers.
•Operate only in a fume cupboard with protective safety sash.
•During and after heating take care not to touch the eat-On Safety Covers and blocks.
•Risk of burns from hot covers and blocks
Whilst the Safety Cover significantly reduces the temperature of exposed surfaces, it will still be hot and may also increase the
time taken for the eat-On block to cool down after use. A temperature probe or temperature sensitive label can be used to
indicate when blocks and covers are too hot to touch.
•Chemical Resistance
eat-On Safety Covers are manufactured from solid PTFE, providing chemical resistance to the majority of chemicals. owever,
although the eat-On Safety Cover is designed to give additional chemical protection to the eat-On block, it does not provide a
complete sealed enclosure, and care should be taken to avoid any spillage that may result in damage to the block.
•Temperature Range
eat-On Safety Covers can be used on eat-On blocks operating at up to 200°C without damage to the cover or block. Operation
with eat-On block temperatures up to 260°C can be achieved but some distortion to the cover and minor surface degradation to
the eat-On block may occur.

Warning
When placing oil baths, sand baths, polymer coated or aluminium blocks etc onto a stirring hotplate the increased surface
area will reflect heat back to the stirring hotplate. In such instances care should be taken to ensure that the hotplates
external housing does not exceed the maximum temperature recommended by the manufacturer. Such overheating can
cause damage to internal and/or external parts and lead to failure of your stirring hotplate.
Warning
Always refer to the manufacturers operating instructions for your stirring hotplate before using it with eat-On to be sure
of any limitations or safety restrictions.
Optimising the temperature performance of Heat-On
The heating performance of eat-On will be affected by:
1. The limit of the maximum operating temperature of the stirring hotplate.
2. eating power (Watts) of the stirring hotplate.
3. Flatness of the top plate on the stirring hotplate.
4. Ambient temperature.
5. Load to be heated.
6. Maximum housing temperature of the stirring hotplate.
7. Whether you use a separate temperature controller (probe) see overleaf.

eat-On Instructions
Using a separate temperature controller
For accurate temperature control of your block and/or solution temperature we recommend using a temperature controller such as the
509-67910-00 Temperature Sensor Pt 1000 (V4A) or 509-67920-00 Temperature Sensor Pt 1000 (glass coated).
All eat-On blocks feature a hole (3.5mm ID) for inserting a temperature probe.
Warning
Temperature controller wire/cable should not come into contact with the eat-On Block. Always rotate the block to ensure
that the probe hole is nearest to the probe socket on the stirring hotplate.
Important Note
Please note that typically temperature controllers should be set between
5˚C and 15˚C above the boiling point of the solvent to achieve a gentle reflux.
Optimising the stirring performance of your Heat-On
The eat-On system uses the magnetic field of the stirring hotplate to stir your sample. The eat-On blocks have been optimised to work
with leading brands of stirring hotplates with a top plate diameter of up to 145mm.
The stirring performance of eat-On will be affected by:
1. The limit of the maximum stirring speed of the stirring hotplate.
2. Power and size of the magnet within the stirring hotplate.
3. Selection of an appropriate magnetic stirring bar for your chosen flask
4. Viscosity of sample.
Wide choice of magnetic stirring bars
The selection of an appropriate magnetic stirring bar for your chosen flask is key to the
performance of stirring within the eat-On block.
For more information on suitable stirring bars please contact eidolph or your local distribu-
tor.

Fitting optional safety lifting handles to Heat-On blocks
Safety lifting handles have a simple and secure quick release mechanism that allows the
user to quickly attach the handles and move the block while it remains hot.
The handles are attached to the block or holder as follows:
1. Take handle and push button on top (as shown in picture to the right).
2. Slide handle into the stainless steel insert.
3. Release button.
To remove handle, simply press down on button and pull handle out.
Warning
Extreme caution should always be used when lifting hot vessels or objects.
Please check with your laboratory safety officer to ensure that you are
complying with all relevant safety procedures.
Many laboratories do not permit the handling of hot liquids or objects
and therefore the use of the optional handles may not be permitted
within such a laboratory.
Warning
andles should always be removed from block when heating. If handles are
left in block whilst heating they will become hot.
andles should always be removed
from block when heating. If handles
are left in block whilst heating they
will become hot.
Warning
Always wear heat resistant gloves when handling hot blocks - even when
using the lifting handles.
Using a retort stand
To increase user safety Radleys recommend the use of a retort stand with eat-On blocks,
adding further stability to the system, particularly when using the larger blocks.
We find it best to locate the stand to the rear of your set-up thus avoiding any obstruction
when using hotplate controls.
!
Warning
When lifting the block using the handles, always be sure to touch only the
handles and not the block itself, which may be too hot to touch and
may cause injury.

Description of Problem
1. The flask does not spin freely and therefore is deformed and is catching or sticking on the inside of the well.
The flask may well crack when the eat-On block cools.
2. There is grit or an object between the flask and the well.
3. The flask was sealed with a closure or cap and there was a build up of pressure in the flask during heating.
4. The flask was scratched, or cracked and failed due to weakness.
5. The flask was not properly annealed during manufactured and has cracked due to stress.
Remedy
1. There is simple rule when using glassware with the eat-on: “If it does not spin, then throw it in the bin”. If the flask
does not spin freely then it is unsuitable for use in the eat-On and an alternative flask should be used.
2. Always thoroughly clean the eat-On block before and after use.
3. Never heat sealed glass vessels, unless they are specifically pressure rated.
4. Never use glassware that shows signs of scratching, cracking or has chips, as this causes inherent weaknesses in the
glass strength.
5. Always buy glassware from reputable sources.
Warning
Factors that could lead to a flask failure...

Set-Up of PTFE Safety Covers
1. Follow the set-up procedure for the Stirring otplate and eat-On block as described
previously.
2. Ensure that you have the correct Safety Cover for the eat-On block that you are using.
You can check this by matching the size information inscribed on the PTFE Cover with
that on the eat-On block.
3. Carefully position the eat-On Safety Cover over the eat-On block. Check that the Cover
is properly located and fitting on the block securely. There should be adequate clearance
between the inner circumference of the eat-On Safety Cover and the inner rim of the
eat-On bowl, such that there is no obstruction when glassware is positioned in the block. The PTFE cover should turn freely
on the eat-On block.
4. Rotate the cover until the access holes for the eat-On safety lifting handles and Temperature Probe in the cover are correctly
aligned with the respective holes in the eat-On block.
5. Load Glassware: Select the appropriate glassware for your application. Ensure that the glassware is fully compatible with the eat-
On block and Safety Cover to be used. Position the glassware in the eat-On block. Check that the glassware is properly located in
the block, and not constrained in anyway by the eat-On Safety Cover.
Set-Up of PTFE Safety Covers for Multi-Well Block
A dedicated Multi-Well Safety Cover is available for the eat-On Multi-Well older, which is fully
compatible with the full range of inserts. Simply place the Multi-Well older directly on to
the hotplate, position the PTFE Safety Cover and rotate so that the central cut out of the cover
is correctly aligned with; the locating rings in the Multi-Well older; and the access holes for eat-
On safety lifting handles and Temperature Probe.

Vielen Dank für den Einkauf Ihres Heat-On
Bitte lesen Sie die Betriebsanleitung gründlich durch, bevor Sie Ihr Gerät in Betrieb nehmen.
Einführung
Das eat-On System ist ein modularer Arbeitsplatz zum Verrühren und Aufheizen, dessen Design den
Einsatz von einer bzw zwei Rundkolbenflaschen von 10ml bis zu 5 Liter erlaubt.
Die optionalen PTFE Sicherheitsabdeckungen wurden zur Ergänzung und zur Verbesserung der Leistung und Sicherheit der
eat-On-Blöcke konzipiert.
Das eat-On System bietet die folgenden Eigenschaften und Vorzüge:
•Alle eat-On Blöcke werden aus Vollaluminium hergestellt, wodurch eine exzellente, gleichmäßige
Wärmeübertragung auf den gesamten Block gewährleistet ist, ohne dass Wärmeinseln entstehen.
•Das schlanke, gewichtssparende Design sorgt für eine verringerte Masse des zu erhitzenden Blocks, mit verbesserten Aufheizzeiten.
•Die einzigartig geformten eizblöcke maximieren die Auflageoberfläche von Kolben was zu einer Verbesserung
der Aufheizzeit und gleichzeitig zu einer Minimierung der Temperaturdifferenz zwischen Block und Lösungsmittel führt.
•Fluorpolymerbeschichtung sorgt für eine zusätzliche altbarkeit.
•Tests haben bewiesen, dass ein 250ml Kolben gefüllt mit Wasser in weniger als 9 Minuten zum Kochen
gebracht werden kann, 50% schneller als Konkurrenzprodukte.
•Alle eat-On Blöcke verfügen über eine Bohrung zur Aufnahme eines externen Temperaturmessfühlers.
•eat-On Blöcke können auf Temperaturen von bis zu 200˚C erhitzt werden ohne Beschädigungen an den Blöcken hervorzurufen. Es
können Temperaturen bis zu 260˚C erreicht werden, hierbei können jedoch geringfügige Oberflächenverformungen auftreten.
PTFE Sicherheitsabdeckungen
Diese innovativen und soliden PTFE-Sicherheitsabdeckungen verringern das Risiko, dass der Benutzer den heißen eat-On-Block
berührt, und sorgen gleichzeitig für einen geringeren Energieverbrauch...
• Die PTFE-Isolierung verringert die Temperatur der möglichen Kontaktflächen um bis zu 50% und stellt bei hohen
Temperaturen eine Thermo-Sicherheitsbarriere für den Bediener dar.
• Die PTFE-Isolierung verringert die erforderliche Energie zum Aufheizen des eat-On-Blocks um bis zu 15%
• PTFE deckt die heißen Metallflächen ab und verhindert, dass Lösungsmittel auf die heißen Flächen verspritzt werden können
• Das chemisch beständige PTFE hält Temperaturen bis zu 260˚C stand
• Die Abdeckungen lassen sich sehr einfach über den vorhandenen eat-On-Blöcken anbringen
• Alle eat-On-Sicherheitsabdeckungen verfügen über eine Bohrung zur Aufnahme eines externen Temperaturmessfühlers

Die folgenden Symbole verfolgen die Absicht, den Nutzer zu einem sicheren und effizienten Betrieb des eat-On anzuleiten.
Wichtige VORSICHTSMAßNAHMEN
1. Bitte lesen Sie diese Anweisungen vollständig durch, bevor Sie Ihren Heat-On Block verwenden.
eat-On darf nur von entsprechend geschulten und kompetenten Mitarbeitern bedient werden. Wie immer beim Umgang mit
Chemikalien muss vor der Inbetriebnahme eine vollständige Risikobewertung durchgeführt werden, und die Reaktionen müssen in
allen Phasen sorgfältig überwacht werden. Während des Betriebs darf eat-On nicht unbeaufsichtigt bleiben, außer in einer
überwachten Umgebung.
2. Nehmen Sie das Gerät nur in einem Abzugsschrank mit Sicherheits-Schieberahmen in Betrieb.
3. Achten Sie darauf, den Heat-On Block während und nach der Erhitzung nicht zu berühren.
4. Verbrennungsgefahr durch die Heizblöcke
Wie Ölbäder bleiben auch die eat-On Blöcke für einen beträchtlichen Zeitraum heiß, nachdem die eizquelle abgeschaltet wurde.
Es kann ein Temperaturmessfühler oder ein temperaturempfindlicher Aufkleber benutzt werden, um anzuzeigen, ob die Blöcke für
eine Berührung zu heiß sind. Die Verwendung der eat-On PTFE-Sicherheitsabdeckungen verringern auch das Risiko, dass ein
Benutzer den heißen Block berührt.
5. Vorgang Kolbenauswahl
Das eat-On System ist so konstruiert, dass Kolben in Übergrößen nicht durch die leicht verengte Öffnung oben am Blockbehälter
passen. Dies bedeutet, dass alle geeigneten Kolben, mit einem lockeren Sitz, unten auf dem Blockbehälter aufsitzen, so dass sie
sich frei beweglich im eat-On-Behälter herumdrehen lassen.
Wenn ein Kolben in den Behälter eingesetzt wird, dann ist es wichtig sicher zu stellen, dass der Kolben den Boden des Behälters
berührt und sich nicht an seinen Seiten verfängt oder anhaftet. Sollte sich der Kolben verfangen oder anhaften, kann er sich verfor-
men was dazu füren kann, dass der Kolben festklemmt und Glasbruch eintritt, wenn sich der eizblock abkühlt.
Es gibt eine einfache Regel für die Nutzung von Laborglaswaren mit dem eat-On System: Ein Kolben, der sich nicht frei herum-
drehen lässt, ist ungeeignet für die Nutzung im eat-On System, und es sollte ein anderer Kolben verwendet werden der sich frei
drehen lässt.
Bei der Konzeption von eat-On wurden Kolben von verschiedensten Glasherstellern getestet und bewertet, um sicherzustellen, dass
die eat-On-Blöcke ein breites Spektrum von Größen und Formen akzeptieren. Die Massenproduktion von Glaswaren erlaubt jedoch
erhebliche Toleranzen, daher kann keine Garantie dafür übernommen werden, dass alle Fabrikate in das Gerät passen. Die
Erfahrung zeigt, dass Glaswaren von einem einzigen ersteller sich je nach Fertigungslos und auch von Stück zu Stück erheblich in
Größe und Form unterscheiden können. In diesen Fällen müssen Kunden eventuell eine Vorauswahl geeigneter Glasgrößen zur
Verwendung mit eat-On treffen.
Vorsichtsmaßnahme
Ist zu beachten, wenn die Möglichkeit einer
persönlichen Verletzung besteht.

t6. Start und Anhalten Ihrer Reaktion
Unter idealen Bedingungen sollten Sie Ihre Glasware bei Raumtemperatur (=Blocktemperatur) in den Block einsetzen.
In manchen Situationen ist dies jedoch nicht praktikabel; unter diesen Umständen sollten Sie folgendes beachten: -
a. Sie können kaltes Wasser nutzen, um den Block rasch zu kühlen, aber achten Sie bei Temperaturen über 100˚C darauf, dass der
Dampf ein potentielles Risiko darstellt.
b. Es ist generell sicher, Kolben in den Block einzusetzen, wenn dieser eine Temperatur unter 50˚C hat, der Kolben sollte aber her-
ausgenommen werden, bevor die Blocktemperatur unter die Starttemperatur sinkt, da ein geringfügiges Risiko besteht, dass
dadurch die Kontraktion des Blocks den Glaskolben zerbricht.
c. Glaskolben sollten immer bei oder über der temperatur entfernt werden, bei der sie ursprünglich eingesetzt wurden: z.B. sollte ein
Glaskolben der bei 80˚C eingesetzt wurde spätestens dann entfernt werden, bevore der Block wieder auf 80˚C abkühlt.
7. Chemische Beständigkeit
Eloxierte eat-On-Blöcke sind beständig gegen eine Vielzahl von Lösungsmitteln und bei Raumtemperatur unempfindlich gegen
Spritzer verdünnter Säuren und Laugen. Die Fluorpolymerbeschichteten eat-On Blöcke haben eine gute Beständigkeit gegen
Lösungsmittel, Säuren und Laugen. Die Langzeiteinwirkung von Säuren oder Laugen wird die Oberfläche der eat-On Blöcke
angreifen. Je stärker die Konzentration und je länger die Einwirkungszeit, um so höher die Wahrscheinlichkeit und Schwere einer
Beschädigung. Des Weiteren beschleunigt und intensiviert itze jegliche Art von Beschadigung. Konzentrierte Schwefelsäure wird
nach einer bestimmten Zeit die Fluorpolymerbeschichtung der eat-On Blöcke angreifen. Es ist daher wichtig, alle Rückstände von
Chemikalien sofort zu reinigen, nachdem sie auftreten.
8. Temperaturumfang
eat-On Blöcke können auf Temperaturen von bis zu 200˚C erhitzt werden ohne Beschädigungen an den Blöcken hervorzurufen. Es
können Temperaturen bis zu 260˚C erreicht werden, hierbei können aber geringfüge Oberflächenverformungen auftreten.
9. Verwendung der optionalen PTFE-Sicherheitsabdeckungen
•Die eat-On Sicherheitsabdeckung wurde zum Einsatz in Verbindung mit eat-On-Blöcken konzipiert. Bitte vergewissern Sie
sich, dass Sie die eat-On-Bedienungsanleitung vollständig gelesen haben, bevor Sie die eat-On Sicherheitsabdeckungen ver-
wenden.
•Betreiben Sie das Gerät nur in einem standardmäßigem Laborabzug.
•Achten Sie während des Aufheizens und danach darauf,
die eat-On-Sicherheitsabdeckungen und -Blöcke nicht zu berühren.
•eiße Abdeckungen und Blöcke können zu Verbrennungen führen
Die Sicherheitsabdeckung verringert zwar die Temperatur der frei liegenden Flächen
erheblich, diese sind jedoch noch immer heiß. Außerdem kann es nach dem Einsatz länger dauern, bis diese Flächen abgekühlt
sind. Es kann ein Temperaturmessfühler oder ein temperaturempfindlicher Aufkleber benutzt werden, um anzuzeigen, ob die
Blöcke für eine Berührung zu heiß sind.
•Chemische Beständigkeit
eat-On Sicherheitsabdeckungen wurden aus solidem PTFE gefertigt und sind gegen die meisten Chemikalien widerstandsfähig.
Auch wenn die eat-On Sicherheitsabdeckung den eat-On-Block zusätzlich gegen Chemikalien schützt, so stellt er doch kein
vollständig versiegeltes Gehäuse dar. Achten Sie daher darauf, keine Chemikalien oder Substanzen zu verschütten, die den Block
beschädigen könnten.
•Temperaturbereich
eat-On Sicherheitsabdeckungen können mit eat-On-Blocks auf Temperaturen von bis zu 200°C erhitzt werden, ohne dass
die Abdeckung oder der Block beschädigt werden. Der Betrieb mit Temperaturen bis zu 260°C am eat-On-Block ist möglich,
allerdings kann sich die Abdeckung etwas verformen und die Oberfläche des eat-On-Blocks etwas verschlechtern.
