If applicable, follow the previous steps to install a suction module on a second rack. •
Switch on the Scrubber or water jet pump and activate the fume hood ventilation. •
➡The rack(s) can now safely be processed in the SpeedDigester.
Note
Clean all glass parts before mounting to avoid cross contamination. •
When a water jet pump is used, hazardous vapours can escape into the environmental air if the •
suction is inadequate.
If a Scrubber without condensation step is used, the condensate that accrues must be absorbed
•
by means of a Woulff bottle between the SpeedDigester K-439 and the Scrubber.
When operating with 3rd party sample tubes no insulation caps and glass caps are available. In
•
this case, all positions must be equipped with samples!
When operating with 300 ml sample tubes, close unused positions with a glass cap towards the
•
suction unit.
6 .7 .4 Installing 500 ml sample tubes
Unlike 300 ml (and 250 ml) sample tubes, 500 ml tubes can not simply be inserted into the appro-
priate rack. The information in this section serves to set up this type of sample tube properly and
safely in the rack.
Installation steps:
For installation and handling all parts must be < 40 °C!
