VACUUM+FILTRATION DESICCATORS, 200 mm, KAR230

PRODUCT DESCRIPTION

Implosion proof desiccators. Will take vacuum of -740mm/HG with loss (absolute zero: -760 mm/HG) not exceeding 20 mm/HG in 24 hours. The transparent polycarbonate cover seals onto a neoprene 'O' ring set into the flange of the PP base. A little grease spread on the 'O' ring will assist in establishing the initial vacuum. Within the desiccator is a removable pan for holding a drying agent. Vacuum release tap/nonreturn valve assembly included (Art. 229); specially grooved stopper in this assembly allows air, when required, to be re-admitted very slowly to avoid disturbing the contents.

Usage Instructions:

   - Remove the cover in PC - insert the samples in the pan

   - Open the vacuum retention valve (PE needle) and connect the tube of the pump to the desiccator spigot in order to create a vacuum retention valve.
