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

EXTRA-HEAVY WALLS
Clear polycarbonate top and white polypropylene bottom (clear base is polycarbonate) have extra heavy walls to eliminate the danger of implosion. This strong, shatterproof desiccator will hold a vacuum of 740mm of Hg (.09MPa) for a period of 24 hours. Maximum temperature 130°C (266°F).

STOPCOCK WITH PTFE PLUG
The polypropylene stopcock has a 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 1/4" (6.4mm) I.D. tubing.

NEOPRENE O-RING
O-ring 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 SECTION
Provides 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 1/8" (3.2mm) thick with 1/8" diameter perforations for air transfer. Plate rests on the retaining ledge of bottom section and has a center hole for easy removal. Desiccant needs to be purchased separately.

desiccant cartridge

Cartridge Desiccant

Eliminate the messy, time-consuming job of changing loose desiccant. Convenient, easy-to-handle Desiccant in a Cartridge fits into the bottom section of standard glass or plastic desiccators. The cartridge consists of a durable polyester-felt bag with a perforated Mylar® cover sealed in place. It is filled with indicating silica gel beads which change color from blue when dry to pink when moist. Saturated gel can be regenerated in a 300°F (150°C) vented oven for 3 hours or more (depending on size) until blue color returns. May be reactivated repeatedly without degradation. Individually sealed in a moisture-proof pouch.

Vacuum-Pressure Indicator

see at a glance whether your desiccator is under vacuum or not

Easily confirm vacuum within a Space Saver Vacuum Desiccator with the Vacuum Pressure Indicator. The bellows collapse when there is negative pressure vacuum within the desiccator and expand under ambient atmospheric pressure. The indicator fits on the tapered outlet of desiccator stopcock without requiring special tools.
