Appropriate Use
The in-line heating unit serves for heating
samples in appropriate vessels, as, for
example, fat extraction with petroleum
ether or heating under reflux. Round-
bottom flasks and other vessels with small
contact surface may only be used with the
appropriate flask adapters. Heating the unit
without dissipating the heat that is being
produced can destroy the heating plates.
The in-line heating unit is not suitable
for non-intermittent operation at high
temperature.
Do not make arbitrary alterations in the unit.
These could affect its safety and reliability
and will void the product guarantee.
Do not expose the device to aggressive
vapours e.g. of acids, bases or solvents!
Non-appropriate use will make the
guarantee void.
The in-line heating unit must only be
connected to a mains receptacle of
sufficient load capacity. For the 8-place
versions, a fuse protection of 16 A is
recommended.

Assembling the
behrotest®In-line extraction unit
Danger of toxic solvent vapours! Always conduct the extraction in a fume
hood.
Danger of electric shock! Make sure that no liquids get into the cable
connections or the inside of the equipment.
Glass can break and cause injury! In working with glass components,
observe all appropriate safety precautions.
Attaching the
Vertical Support Bars
Place the in-line heating unit on a flat level
surface.
Attach both vertical support bars to the
side of the in-line heating unit using the
four knurled screws provided.
Befestigen Sie die beiden Standpfosten
mit den 4 Rändelschrauben an der
Rückseite der Reihenheizbank.
Make sure the lower ends of the support
bars, which are to be attached to the
heating unit, are resting on the bench
top. The angle bracket for attaching the
support bars has elongated slots for
inserting the screws. This allows you to
adjust the vertical height of the support
bars.

Attaching the
Horizontal Support Bars
Bars with Extractor Mountings
Insert the bars with the extractor
mountings from below between the
internal track formed by the horizontal
support bars. The extractor mountings
must be oriented with the slotted
opening on top, facing forward.
The correct height of attachment for the
horizontal support bars depends on the
glassware being used. For example,
in the case of the 100 ml Soxhlet
extraction, locate the screw holes of
the upper horizontal support bar at the
lower ends of the third elongated slots
in the vertical support bars. The height
can be readjusted as needed at any
time in the future.

Fasten the horizontal support bars with
the four knurled screws provided.
