You can ll the heating bath with various heating bath uids:
▪Tap water (no deionized or distilled water)
▪Water soluble polyethylene glycol
▪Oil with low viscosity (40 cP) and ashpoint > 285°C.
Danger/ Danger
Risk of explosion! / Danger d’explosion !
Heating bath uid oil with a ashpoint < 285 °C might ignite and lead
to uncontrollable thermic reactions and explosion./
Chauer avec un bain marie de l’huile ou un liquide avec un point
d’inammation < 285 °C est dangereux car il pourrait s’enammer
avec des températures élevées et conduire à des réactions thermiques
incontrôlables et à des explosions.
➜Only use > 285 °C ashpoint oils./
N’utiliser que des huiles avec un point éclair > 285°C.
The marks inside heating the bath show the minimum and maximum level for heating
bath uid with evaporating ask completely immersed.
Evaporating ask is immersed by moving up and down via the heating bath lift.
When heating bath lift is moved downwards the evaporating ask
displaces already lled in uid.
To prevent heating bath from overow:
▪Move down the lift with evaporating ask mounted before lling bath.
▪Fill in heating bath uid till the maximum level mark is reached.
Do not let the evaporating ask touch the bottom or the edge of the
heating bath.
(To adjust the evaporating ask depth and ask angle please view
chapter “Assembly”, section “Evaporating ask: Adjust Evaporating
ask angle and depth”.)

Adjusting ask rotation
By increasing ask rotation you can increase your evaporation rate. A shorter evaporation
time may prevent thermal damage to your sample.
Depending on ask size and heating bath temperature dierent rotation speeds may be
suitable.
Speed range and setting
Rotation speed can be set from 10 rpm - 280 rpm.
Warning:
Risk of scalding and slipping!
At high ask rotation speeds bath uid may splash or spill over and
result in a slippery oor and/or severe scalding.
If you are operating the device without a safety hood:
▪Run a test with your heating bath uid temperature and rotation
speed and document any size of splashing.
▪Ensure that this documentation is communicated and accessible to
all individuals.
▪Wear safety clothes if you are working in near proximity to the
device.
▪Pay attention to any amount of heating bath uid on the oor.
Avertissement :
Risque de brûlures et de glissade !
La vitesse de rotation rapide du acon peut provoquer des
éclaboussures ou des débordements rendant le sol glissant et/ou
entraînant des brûlures graves.
En cas d’exploitation de l’unité sans capot de protection :
▪Pratiquer un test avec la température et la vitesse de rotation du
bain marie et noter le volume des éclaboussures.
▪S’assurer que ces notes sont communiquées et mises à disposition
de tous les individus.
▪Porter des vêtements de protection lors du travail à proximité de
l’unité.
▪Faire attention à toute quantité de liquide de bain marie répandu sur
le sol.
➜Test your selected uid
▪with slowly increasing temperatures
▪with dierent evaporating asks
▪with increasing rotation speeds
➜Note these results and make them accessible for all contributors.
Depending on the oil and age of oil you are utilizing the heating bath
temperature may change the viscosity and the volume of the bath
uid.
Keep records of the exact description/manufacturer information and
period of use and repeat the documentation in the determined time
interval.
