Operation and controls
Installing vessels: Universal adaptor
The construction of the universal adaptor allows to fix different vessels with ground-in
stoppers or screwed caps as well as complete test tube racks.
Dimensions of vessels suitable for usage:
▪ height min./max. 45 mm/160 mm
▪ width max. 230 mm
➜ To that end, the two quick-clamping
nuts are loosened by turning them
once or twice.
➜ When they are in an inclined position,
the quick-clamping nuts can be moved
along the threaded bolt.
✓ The universal adaptor can be
opened to a width from 45-160 mm,
depending on the case of application.
➜ Then the vessels or the test tube rack
can be put into the adaptor, as shown
in the illustration.
➜ Next the cover plate is pressed down
and secured with the quick-clamping
nuts. (To this end, move the quick-
clamping nuts along the threaded bolt
and tighten them by turning them
once or twice.)

Installing vessels: Adaptor 1
Adaptor 1 can hold 20 test tubes with diameters from 10 -18 mm.
A tension ring runs above the gap of the
test tubes in two levels.
➜ Pull the tension ring on the 1st level
above the gap towards the middle of
the adaptor.
➜ Move the test tube in front of the
tension spring through the gap, so that
the tension ring pushes the test tube
against the narrow side of the gap to
the outside.
➜ Move the test tube further through the
2nd level and repeat to tensioning the
spring.
