Desiccators are made of Polypropyelene and Polycarbonate. These autoclavable vacuum desiccators can hold vacuum upto 740mm of Hg for 24 hrs. without any greasing.
The top dome, moulded in rigid and transparent POlycarbonate, gives a crystal clear view of the desiccant placed inside. The knurled knob on the top provides easy handling of the dome . The lower part is made of Polypropylene. An internal groove is provided on the flange to hold a silicon rubber O-ring.
The Polypropylene stopcock is fitted with a seld lubricating PTFE plug. This plug works three way i.e. vaccum creation, shutting off and vaccum releasing.
Each desiccator is provided with a thick perforated Polypropyelene disc with a big hole in the centre for easy lifting. The tiny holes in the disc provide air troughs & support to the dishes. However porcelain discs are advisable in case of incandescent crucibles.
