The superior dehumidification performance of the Autodesiccator model makes it a natural choice for more perishableand expensive products that require constant low humidity. Totally automatic, continual desiccation with silica beads, and generation every 20 minutes, keeps RH level in the SECADOR™ 4.0 Desiccator at a constant level. No long regeneration lag between cycles - minimal change from opening the cabinet door. Two fans guarantee continuous airflow within the cabinet, and continuous exhaust of humid air.

Dry Keeper Plus Desiccator Cabinet; Non-Vacuumarrow12Dry Keeper Plus™ Desiccator Cabinet; Non-Vacuum

Efficient dehumidification is monitored by a hygrometer dial in the door. The dehumidifying auto-drying unit has an air circulating system which helps drop relative humidity sharply through its cycling of absorption and regeneration of the enclosed permanent desiccant. It can bring the relative humidity down from 60% to 10% in 6 hours of continuous operation in an unloaded cabinet. The unit comes with three clear, removable shelves with vent holes which provide evenly spaced storage area. It operates on 110 volts, 60 Hz., 10 watts, and comes with a 2-prong 6 ft (2 meter) cord.

Overall measurement: 12.2" x 13.9" x 16.9" (310 x 353 x 430mm)

arrow14Glass Desiccators

Glass vacuum desiccators are versatile and are equipped with a sidearm for connection to a vacuum source. The contents of the sealed avacuated desiccators are maintained in a dry reduced pressure atmosphere. Dried materials are stored in desiccators while cooling in order to minimize the uptake of moisture.

Applications:

Dry Seal Vacuum Desiccatorsarrow12Dry Seal® Vacuum Desiccators

The top part of the desiccator is clear, molded from polycarbonate and see-through from any angle. A polyethylene stopcock with a PTFE plug allows for gentle releasing of the vacuum. A peripheral flange around the polypropylene bottom section fits into and snap locks therefore sealing the two halves against a “O” ring. Vacuum retention rating is 740 mm Hg (29”). Inside dimensions are 102mm (4”) diameter x 59mm (2 7/16”)high. The base is 175mm (6 7/8”) diameter.

Reusable Disposable Desiccant Cartridge arrow12Reusable/ Disposable Desiccant Cartridge

These desiccant cartridges can be used in desiccator cabinets or non-vacuum desiccators, analytical balance cases, and precision laboratory instruments. The clear polystyrene dish allows for instant visual inspection of the silica gel color which changes from blue to pale pink as it absorbs moisture.

A highly porous membrane covers the dish of the desiccant providing good moisture absorption. The desiccant can be regenerated by heating cartridges in an oven at 50°C (122°F) overnight. For rapid drying, cut the membrane and transfer the spent gel crystal into a glass or porcelain dish. Then place it in a 150°C (302°F) oven for one hour.

The silica gel is inert and non-toxic. Each cartridge is individually sealed in aluminum foil. Dispose of the cartridges after repeated use. Cartridges come in two sizes: Small: 2½"(65mm) diameter and Large: 4" (100mm) diameter.

Reusable Desiccant Canister arrow12Desiccant Canister; Reusable

Ideal for dry control of desiccator cabinets. Moisture is absorbed through the perforations in the aluminum case, which contains silica gel. This 2 x 4" canister maintains a safe level of humidity in 3cu.ft (0.8 cu. meter) area. When the monitor window turns pink, the silica gel is saturated. It can be regenerated in a 300°F (150°C) oven in about 3 hours. The monitor window will be blue in color when recharged.

Regenerates Repeatedly without Degradation

These cartridges fit into the bottom of a standard glass or plastic desiccator. The cartridge consists of a durable long wearing polyester felt bag with a perforated Mylar cover sealed in place. The indicating gel beads will change their color from blue when dry to pink when moist. Saturated gel can be regenerated in a 150°C (300°F) vented oven for 3 hours or more (depending on size), until the blue color is restored. Cartridges come individually sealed in a moisture-proof pouch ready to use.
