2 Safety
This chapter highlights the safety concept of the fraction collector and contains general rules of
behavior and warnings from hazards concerning the use of the product.
The safety of users and personnel can only be ensured if these safety instructions and the safety-
related warnings in the individual chapters are strictly observed and followed, therefore, the manual
must always be available to all persons performing the tasks described herein.
2.1 User qualification
The instrument may only be used by laboratory personnel or other persons who on account of training
or professional experience have an overview of the dangers which can develop when operating the
instrument.
Personnel without this training or persons who are currently being trained require careful supervision.
The present Operation Manual serves as a basis for training.
2.2 Proper use
The Fraction Collector C-660 has been conceived of and constructed as a laboratory instrument. Its
correct usage is the optimal and reliable collection of individual aqueous and/or organic fractions in
predetermined or customized racks (e.g. chromatography or Syncore racks).
Correct usage of the Fraction Collector C-660 also includes its maintenance and careful handling of
the instrument on the basis of the specifications given in the Operation Manual.
2.3 Improper use
Applications beyond those described above are improper. Furthermore, applications which do not
comply with the technical data are also considered improper. The operator bears the sole risk for any
damages caused by such improper use.
The following applications are expressly forbidden:
• Use of the instrument in rooms which require ex-protected instruments.
• Collection of samples which can explode or inflame due to shock, friction, heat or spark formation
or that are combustible (e.g. explosive substances, etc.)
• Use in human medicine diagnostics.
• Preparation of food.

4.2 Function principle
The fraction collector is characterized by the following features:
• Up to 12 liters (48×250 mL) or up to 240 fractions of 20 mL can be collected.
• All Syncore racks are predefined.
• A simple teach-in enables the definition of up to 11 user-specific rack types.
Other features include:
• Fractionation with or without detector.
• Integrated RS-232 interface for data transfer to PC.
• Integrated peak detector.
• Two detector inlets and two recorder outlets.
• Optional monitoring of the waste bottle level.
• Optional waste diverter valve recommended for flow rates > 10 mL/min.

5 Putting into operation
This chapter describes the installation of the fraction collector and gives instructions on initial start-up.
NOTE
Inspect the instrument for damages during unpacking. If necessary, prepare a status report imme-
diately to inform the postal company, railway company or transport company. Keep the original
packaging for future transport.
5.1 Installation site
Place the instrument on a stable, horizontal surface, so that the rear side remains accessible and
consider the maximum product dimensions.
To avoid annoyance caused by bad smells or possible damage to health caused by volatile solutions,
we recommend setting up the Fraction Collector C-660 with an exhaust system. It should thereby be
ascertained that the instrument is not exposed to aggressive substances such as acids, bases and
solvents, which can have a negative influence on the useful life.
WARNING
The fraction collector is not explosion proof. Potential explosion risk.
• Never position potential ignition sources near the Fraction collector.
• Operate the instrument in a fume hood or in an adequately ventilated work area.
5.2 Electrical connections
ATTENTION
Make sure that the voltage on the socket corresponds to the voltage given on the type plate of the
instrument.
Ensure that the instrument is earthed. External connections and extension cables must be provided
with an earthed conductor lead (3-pole couplings, cable or plug equipment) as the mains lead has a
molded plug to avoid risks due to inadvertent defective wiring.
Make sure that no electric sparks form in the instrument or its surroundings as they might damage
the instrument.
An electrostatic discharge can damage the instrument and lead to fire.

The tubing acontaining the fraction comes
from the chromatography column. The fitting
band ferrule care attached to the free end.
Mount the fitting band ferrule c.
Press the suction tubing aand the ferrule c
against a table surface to firmly seal the tubing
end with the ferrule.
Fig. 5.2: Installing fitting and ferrule
5.3.3 Optional waste diverter valve
If the flow rate of the pumps exceeds 10 mL/
min a waste diverter valve is recommended.
To install the waste diverter valve, proceed as
follows:
Screw the tubing coming from the detector
into the inlet a. Outlet bleads to the collec-
tion arm of the fraction collector.
Ensure that the FEP tubing cis long enough
to reach even the farest corner position of the
collector arm h. Outlet dleads to the waste
bottle.
The waste diverter valve can be fixed at the
back side of the fraction collector.

The collector head e is found on the collec-
tor arm hof the fraction collector. Clamp the
tubing guide f(metal pipe) tightly into the
collector head g.
Ensure that the height of the tubing guide f
is correct. It should be at least 1 cm above the
tube rim, so that it will not damage the tubing
during operation.
Now direct the FEP-tubing cfrom valve out-
let band afterwards through the tubing guide
f, so that it pokes out approximately 3 mm.
Connect the valve to the WASTE VALVE con-
nection i.

This chapter explains the operating elements and possible operating modes. It gives instructions on
how to operate the Fraction collector properly and safely.
ATTENTION
Check the glassware for damages prior to each operation and use only glassware in perfect condi-
tion. Glassware with cracks, stars or other damages can fail during operation.
Make sure that all fittings and tubings are hand-tight.

For this purpose set the address bus switch to position 1 or 2 (see Fig. 5.4). Now all settings have to
be done within the SepacoreControl software (see Installation Guide SepacoreControl).
