Desiccator with stopcock, PP/PC Ø 250 mm

With a bleed valve and an O-ring seal between the dome and the lower portion. The desiccators are suitable for vacuum and are provided with a non-return valve. Hot crucibles should only be placed on a porcelain plate, and should not come into too close contact with the rim of the desiccator. The insert made of PP serves to hold the drying agent. Desiccator plates should be purchased separately.
