These 304 stainless steel desiccators provide all the humidity control features of our smaller models, along with double doors that afford unrestricted access to the entire storage area.

Made of 304 stainless steel, these cabinets are designed for optimal strength and cleanliness (electropolishing available for the most critical requirements). Static-dissipative PVC viewing windows ensure full visibility of stored parts and minimize the danger of electrostatic discharge that could damage sensitive components. Stainless Steel LiftLatches, with one-piece, nonoutgassing elastomeric gaskets, seal each door snugly.

For regular-duty cabinets, select as many optional shelves as you require (holds up to 100 lb/shelf); order separately. Each shelf is perforated along the rear edge to permit unrestricted gas circulation, and can be positioned at any height you desire by means of clip supports. Included 4.5" (114 mm) stands allow easy cleaning beneath the cabinet.

Heavy-duty cabinets can hold up to three reinforced shelves, each with a load capacity of 300 lb. For storage of moisture-sensitive bulk powders or chemicals using dry-storage drums, see Terra's Humidity-Controlled Dry Storage Cabinets.

For optimal humidity and particle control, select the optional Dual Purge™ System and NitroWatch® Humidity Controller. The Series 300 cabinets come equipped with two Automatic RB® (Relief/Bleed) Valves to ensure safe pressure relief, as well as a Flowmeter to monitor pressure and regulate gas.
