The regional and local laws and regulations must be obser-
ved. It is necessary to wear personal protective equipment
such as protective goggles, gloves and a laboratory
coat.
It is only permissible to assemble and dismantle certain parts
of the Syncore when such action is necessary to carry out
the functional requirements.
This activity can be performed manually or by use of the tool
which is supplied. Except for authorized maintenance per-
sonnel, the removal of protective devices and cover plates/
shrouding with the aid of a conventional tool is forbidden.
The owner of the company is responsible for the instruction
of his personnel. To assist in this context, it is possible to
order these Operating Instructions in other languages. At all
times, these Operating Instructions must be available - as a
component part of Syncore - to the operating personnel at

Syncore comprises a series of compact, highly versatile
instruments suitable for all aspects of parallel synthesis and
evaporation.
There are three pre-defined assemblies:
• SyncoreReactor
• SyncorePolyvap
• SyncoreAnalyst
The instruments are tailored to the customer’s needs in
various applications. The standard configurations can be
modified to meet individual requirements by using additional
accessories.
3.1 The single platform
The Syncore single platform is equipped with a heater and
a shaking mechanism.
• Heatingisaccomplishedacrossaheatingfoilonabase
plate .
• Temperaturesrangefrom-20°Cto150°C.
The quiet an vibration free staking movement is orbital and
horizontal, with a maximum speed of 600 rpm and an ea-
sily adjustable exxenter of 0 to 5 mm. This ensures that all
samples may be thoroughly agitated vy vortex action within
the tubes, eliminating potential contamination souerces such
as stirrer paddles or magnetic followers.
A shield protects the operator from contact with hot, cold,
or moving parts.
The unit is controlled either manually or via a program. Up
to 9 individual temperature/time steps may be programmed,
each lasting for a maximum of 9 hours and 59 minutes. Pre-
set safety limits may also be selected, 100 or 150°C for the
temperature and 300 or 600 rpm for rotational speed.
Thanks to the two valve outlets, valves may be operated eit-
her under temperature control or controlled by the program.
With programmed control, for example, it is possible to
ensure that the cooling water will not be switched off before
one hour after completion of the program.
The single platform has an analog TTL signal socket that
can process an external start or stop signal. This means that
the unit can be operated via an external control unit, e.g. for
integration into a robot station.
The Syncore single platform has a pre-defined stopping
position. After a vortex movement of the base plate, the
unit automatically re-finds its pre-defined stopping position,
thereby enabling integration of the single platform into fully

3.2 Syncore Analyst R-4, R-6 and R-12
The Syncore Analyst is a prallel work-up station designed
go give high productivity. It comprises a basic unit , a rack
with residual volume cooling for samples with appropriate
glass vessels having residual volume appendices, a vacu-
um connection and a condenser unit with appropriate
receiving flasks .
This parallel evaporator can concentrate up to 12 different
120 ml samples simultaneously down to a pre-defined residu-
al volume from 0.3 to 2.5 ml per sample. The residual volume
is collected in an appendix at the bottom of the sample flask
and is kept cool by circulation water or a suitable coolant
around it until it is removed by the operator. The temperature
of the cooling medium may range between 0°C and room
temperature.
Range of temperatures: Room temperature to 100°C
Maximum sample volume: 120, 250 resp. 500 ml.
Due to its innovative variable throw orbital mechanism, a
strong vortex in the sample is produced (max. speed 600
rpm), thereby preventing evaporation retardation. The ope-
rator can adjust the eccentricity of this vortex movement to
suit the working volume at hand.
The vacuum cover is designed so that each sample has its
own vacuum connection and this combined with baffle, eli-
minates the possibility of cross-contamination. The vacuum
cover is also heated, making it possible to evaporate even
high boiling point solvents to dryness quickly and safely. The
cover is constructed from inert materials such as glass, PFA-
coated aluminium and PTFE-coated sealing discs to ensure
that contaminants cannot leach into the sample.
This makes the Syncore Analyst ideal for applications with
aggressive chemicals, analysis of residues from soils, food-
stuffs, or similar materials, and for thermosensitive products.
3.3 Individual components
The Syncore product line is thoroughly modular. Every acces-
sory is usable at any time with a Syncore single platform and
with all standard configurations.
The different accessories are described in the operating
instruction „Accessories“.

3.4 Syncore Polyvap R-4 to R-96
The Syncore Polyvap comprises a single platform , a rack
for samples and fitting glasses , a vacuum cover ,
and a condenser unit with a suitable receiving flask .
This configuration can be used to condense different samp-
les simultaneously down to dryness.
Range of temperatures: Room temperature to 150°C
Maximum sample volume: From 10 to 500 ml.
The samples are shaken in a horizontal vortex movement at
up to 300 rpm. The operator can adjust the eccentricity of
this vortex movement to suit the working volume at hand.
A simple mechanism permits manual adjustment of a com-
pensating counterweight, thereby ensuring smooth operation
even ath high rotational speeds.
The vacuum cover is designed so that each sample has its
own vacuum connection and this combined with baffle, eli-
minates the possibility of cross-contamination. The vacuum
cover is also independantly heated (up to 70°C), making it
possible to evaporate even high boiling point solvents to
dryness quickly and safely.
The Syncore Polyvap configuration can be used in the most
varied kinds of applications, e.g., for simultaneous evapo-
ration
of samples after synthesis, after chromatography, extraction
(liquid-liquid, solid-liquid), analysis, etc.
For the sake of compatibility, all Syncore racks are already
programmed into the BUCHI Fraction Collector C-660 of
the Sepacore Line.
Other formats and volumes can be processed by using other
optional sample holders (racks) and vacuum covers.

•Concentration
The handling of the device is kept simple. Nevertheless, note
all pertinent safety instructions, particularly the general safety
rules in Chapter 2 of this operation manual, and the indivi-
dual safety instructions provided for the various individual
components (see operating instructions - replacement parts).
5.2 Safety instructions
Chemicals and solvents
The device must be clean before being operated. Residues
of chemicals are to be removed following the general rules
for working with chemicals.
The device must not be put into operation if solvents could
penetrate into it. If that could happen, place the unit in a
well-ventilated fume cupboard and wait until the fumes have
been drawn off completely before operating it.
Whenever the device is being operated with chemicals that
are aggressive, toxic, or likely to cause allergic reactions, it
should always be placed in an fume cupboard.
Indicators, hoses and cables
The Syncore single platform must not be operated if indi-
vidual indicators are not functioning properly and data on
parameters such as time, temperature, or speed are missing.
Live electrical cables and the hoses for the heating and
cooling media must not come into contact with the heated
base plate: They could melt.
Hot and cold parts
Various parts of the unit can be heated or cooled to from
0°C to +150°C. Never touch hot or cold parts with your
hand. No containers used may become either brittle or soft
within the range of temperatures selected.
Maximum temperature
The maximum temperature for the Crystal Rack is limited to
100°C. In that way it is possible to limit the heating of the
Syncore if needed (see chapter 5.6)

5 Operation
Exceeding the maximum temperature
Do not under any circumstances continue using the unit
when the temperature displayed is above 155°C. Contact a
BUCHI service agent immediately in such a case.
Moving parts
Various parts of the accessories are accelerated in the ho-
rizontal plane to speeds of up to 600 rpm. This means that
the machine may cast off parts that have not been fastened
correctly and present a risk for the operator and the labo-
ratory equipment. Whenever you have any doubts about
how well an accessory part has been fastened, switch the
unit OFF immediately and, if necessary, contact a BUCHI
service agent.
Never touch moving parts with your hand or with other
laboratory equipment.
An incorrect speed of rotation, eccentricity, or unbalance
compensation can cause the unit itself or the area around it
to vibrate strongly. In that case, stop the shaking movement
and correct the settings.
The unit must never vibrate so strongly that it can move about
on the base on its own or cause laboratory equipment to
change position.
Never under any circumstance put the unit into operation if
you have any doubts about the condition of these vibration
elements. Inform a BUCHI service agent immediately.
It is not permissible for any objects to penetrate into the
inside of the unit while it is in operation, nor is it permissible
to make any adjustments of the eccentricity or unbalance
compensation under such circumstances.
Noises
If ever any strong noises should occur during operation, take
the unit out of operation immediately and contact a BUCHI
service agent.
Error messages
The unit must not continue in operation after an error message
has been received unless it has been possible to determine the
cause of the error and eliminate the error. Otherwise, contact
a BUCHI service agent.
Refer here also to the chapter, „Error messages.“

is turned and the base plate of the single platform must
move at the speed that has been set.
5. Starting the heating process: Press once on the „Start“
button  to heat the base plate to the prescribed tem-
perature. A dot in the temperature display indicates that
the heater is ON. The running time display shows how
much time has elapsed since starting.
6. Changing the temperature during operation in the manual
mode: The display for set-point temperature must be
activated in a way analogous to points 3 to 5, and the
desired temperature must then be set. After a delay of
3 seconds, the unit then takes over the new set-point
temperature. This does not affect the display for time.
7. Ending the heating process: Pressing once on the „Stop“
button switches the temperature control OFF and the
unit stops heating. This does not affect the shaking
movement.
8. Ending the shaking movement: Turning the speed con-
trol counterclockwise reduces the rotational speed and
