LARGE INTERIOR VOLUME -- The space saving design of the desiccator dome provides maximum interior clearances. They provide an average of 13% greater interior volume than standard hemispherical domes.

EXTRA HEAVY WALLS -- Clear polycarbonate top and white polypropylene bottom. This strong, shatterproof desiccator will hold a full vacuum (29.9" Hg [759mm]) at room temperature for 24 hours and will remain air tight even if not under vacuum.

FEATURING -- A polypropylene stopcock with a Teflon® TFR plug which turns, allowing a slow, gentle entrance of air preventing unnecessary turbulence and crucible damage. The stopcock handle is a highly visible red and has a port which accepts 1/4" (6.4mm) I.D. tubing.
o A large ribbed knob at the top center for easy lifting.
o A Neoprene O-ring seal which does not require grease, but is not harmed if grease is used.
o A polypropylene plate 3.2 mm (1/8") thick with 3.2mm (1/8") diameter perforations for air transfer. The plate rests on the retaining ledge of the bottom section and has a center hole for easy removal.
