Implosion proof desiccators. Will take vacuum of -740mm Hg with loss (absolute zero: -760mm/HG) not exceeding 20mm 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 initial vacuum. Within the desiccator is a removable pan for holding a drying agent. Vacuum release tap/non return valve assembly is included; specially grooved stopper in this assembly allows air, when required, to be readmitted 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 desiccator spigot in order to create vacuum
• Close the vacuum retention valve
