Round vacuum desiccator and accessories

The space-saving design of the desiccator dome provides maximum interior clearances, giving an average of 13% greater interior volume than standard hemispherical domes. Made with a clear polycarbonate top and white polypropylene bottom (clear base is polycarbonate), extra heavy walls eliminate the danger of implosion. This strong, shatterproof desiccator will hold a vacuum of 0.09MPa for a period of 24 hours. Maximum temperature 41°C.

Features:

• Stopcock - Polypropylene with PTFE plug which turns easily, allowing a slow, gentle entrance of air to prevent unnecessary turbulence and specimen damage. Stopcock handle is high-visibility red. Port accepts 6.4mm I.D. tubing. Use VRI-2 or Diaphragm Pumping Kit to evacuate the desiccators.
• Neoprene o-ringNEOPRENE - seal does not require grease, but is not harmed if grease is used. Seal is unaffected by low temperatures down to 0°C.
• Polypropylene bottom - Excellent chemical resistance and permits the use of incandescent crucibles with standard size porcelain plates. The base of the all clear version is polycarbonate.
• Perforated plate - Polypropylene plate supplied is 3.2mm thick 3.2 diameter perforations for air transfer. Plate rests on the retaining ledge of bottom section and has a centre hole for easy removal. Desiccant needs to be purchased separately.
• Vacuum pressure indicator - Only suitable for model ETP2240-1. The bellows collapse when there is vacuum within the desiccator and expand under ambient atmospheric pressure. The indicator fits on the tapered outlet of desiccator stopcock without requiring special tools.
