FILTRATION AND VACUUM DESICCATORS.
Implosion proof desiccators.
Will take vacuum of -740 mm Hg with loss (absolut zero: -760 mm/HG) not exceeding 20 mm Hg in 24 hours.
The transparent polycarbonate cover seals onto a neoprene 0 ring set into the flange of the PP base.
A little grease spread on the 0 ring will assist in establishing initial vacuum.
Within the desiccator is a removable pan for holding a drying agent.
Vacuum release tap/non return valve assembly is 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) connect the tube of the pump to the dessiccator spigot in order to create vacuum.
