Polylab Desiccators are made of Polypropylene and Polycarbonate. The autoclave vaccum desiccators can hold vaccum upto 740mm of Hg for 24hrs. 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 Polyproptlene. An internal groove is provided on the flange to hold a silicon rubber O-Ring.

The Polypropylene stopcock is fitted with a self lubricating PTFE plug. This plug works three way i.e. vaccum creation, shutting off & vaccum releasing.

Each Desiccator is provided with a thick perforated Polypropylene disc with a big hole in the centre for easy lifting. The tiny holes in the disc provede air troughs and support to the dishes. However porcelain discs are advisable in case of incandescent crucibles.
