Used to rapidly dry & dehydrate, these autoclavable Desiccators are made of polypropylene and Polycarbonate. They can be used with or without a vacuum pump and with or without desiccant material (Drierite, etc.).
The chamber will hold vacuum up to 740mm Hg for 24 hours without the need for vacuum grease. The polypropylene stopcock has a self-lubricating PTFE (Teflon-type) valve. If you don't plan on using a vacuum with the Desiccator, just leave the stopcock closed and add your choice of drying agent to the chamber.
Notice: Our 6" model is just as described above, complete with a stopcock for vacuum use.
Our current stock of the 10" Desiccators however, are not vacuum Desiccators and do not have stopcocks - so they obviously cannot be used with a vacuum system.
