K-439 Operation Manual, Version A

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.

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!
