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 the 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 re-admitted very slowly to avoid disturbing the contents.
Desiccator plates:- These plates made of PP are extremely useful as a support for crucibles, petri dishes etc.
- Use at room temperature.
- Not suitable for use with hot crucibles.
