* Acrylic desiccator cabinets are susceptible to damage with the prolonged use of alcohol and other cleaning/disinfecting agents. Desiccator cabinets fabricated out of Static Dissipative PVC may be a better choice in these instances.
** It is highly recommended that stainless steel shields be installed in Static Dissipative PVC desiccators to protect the chambers bottom surface from repeated scraping and rubbing, which can lead to loss of dissipative properties.

Additional product information:

  1. The above reference 3D renderings shown with optional stainless steel door frames, which are listed below.
  2. Amber acrylic desiccator cabinets are ideal for storage of materials and devices that are sensitive to ultraviolet light.
  3. Pre- tapped inlets/outlets for connection of optional gas purge devices & controllers and Auto-Adjust™ RB (relief/bleed) valve.
  4. Static-dissipative PVC desiccator cabinets provide added contamination control by dissipating static charges that attract air-borne particulate.
  5. Exterior removable back plenum panel is made of non-dissipative material. Static dissipative PVC available upon request (at additional charge).
  6. Static-dissipative PVC desiccator cabinets feature system grounding, where the door latch set, hinges and racks are interconnected with conductive tape and terminated at a multi lug grounding block. Grounding is optional on clear and amber acrylic desiccator cabinets. See Grounding (desiccator) option below for further information.
  7. Desiccator cabinet nominal dimensions include the side hinge and catch re-enforcement strips, door hinges and access door(s). Please add 1” (25.4mm) for access door compression lift latch (standard cabinet feature) if overall cabinet depth is needed
  8. Static dissipative PVC desiccator cabinets should not be exposed to extreme heat, direct sun light or prolonged exposure to temperatures above 80 degrees Fahrenheit.
  9. It is highly recommended that heavy objects and/or materials not be placed on top of desiccator cabinets unless the cabinet is properly fitted with the optional stainless steel adjustable shelf supports.
  10. Desiccator cabinets should be periodically cleaned. When doing so, it is recommended that a soft, nonabrasive cloth (micro-fiber) be used along with cold to slightly warm water. If needed, a mild non-abrasive detergent may also be used. Gently wipe the desiccator clean using straight (not circular) motions, replacing the cloth frequently to avoid any un-necessary scratching of the plastic surfaces.

Gas Purge™ Control System:

  • Automatically activates a high-flow gas purge when a chamber door is accessed
  • Protects moisture sensitive materials against oxidation, increasing product yield
  • Ensures a constant positive pressure within glove boxes and other hermetically sealed enclosures to block out contamination influx
  • Dramatically reduces purge gas cost when compared to systems using only a mechanical flow meter
  • Adjustable electronic flow meter precisely regulates the flow rate of the purge gas
  • Digital pressure regulator safely adjusts the pressure of the incoming gas
  • Operates in conjunction with the optional Gas Monitor™ Control Unit to maintain desired sub-ambient moisture level (down to 0% RH)
  • High-reliability door switches are rated for millions of operations. One per desiccator chamber required
  • Works with120/240VAC, 50/60Hz, and requires no manual power selection

The Gas Purge™ Controller monitors and regulates the dry gas that will flow into the desiccator when it is needed to lower the R/H or
when a chamber door is opened. It has a gas regulator to control the pressure of the incoming gas and electronic flow meter that regulates
and maintains the low flow of gas. Also provides audible/visual warnings when the supply gas is getting low, a desiccator door has been left
opened or if the R/H set point has not been reached.

Gas Monitor™ Control System

  • The Gas Monitor™, when used in conjunction with the Gas Purge™ Controller will automatically maintain desiccator R/H levels from ambient down to
    R/H of the purge gas (0% for most dry gases)
  • Incorporates a state of the art micro-controller, a bright readable R/H display and simple control buttons
  • Since the desiccator only needs gas when the R/H rises above the set point, it uses much less gas resulting in large cost savings
  • Small solid state humidity sensor never needs calibration, easily installed and takes a small amount of desiccator space
  • Can be used to monitor R/H levels in any enclosure without the use of the Gas Purge™ controller
  • Works with120/240VAC, 50/60Hz, and requires no manual power selection

The Gas Monitor™ controller measures the R/H of the chamber which contains the Gas Sensor. It has provisions to enter a desired R/H set point and
will issue a command to the Gas Purge™ controller to lower the desiccator cabinet’s humidity level whenever it senses a reading above the R/H set point.
It also monitors the open and closed positions of the desiccator doors and issues a command to the Gas Purge™ controller to introduce dry gas at a
high flow rate while the door is opened and for a preset time after the door is closed (factory set at 60 seconds).

Desiccator Cabinet Grounding:
Static Dissipative PVC features a surface resistivity of approximately 107 ohms/square that dissipates static charges from the cabinet’s surface. Grounding
is standard on Static Dissipative PVC desiccators, which safely directs charges to a multi lug termination grounding block. To protect the Static-Dissipative
PVC interior bottom surface, it is “highly recommended” that a stainless steel shield be installed in each desiccator cabinet chamber. Stainless steel shield
installation includes connection to the desiccators grounding.Acrylic (clear and amber) desiccators can also be fitted with grounding by purchasing the optional “Desiccator Grounding”. Charge for the desiccators grounding
is per chamber. Stainless steel shield installation within these cabinets, include connection to the desiccators grounding if optional grounding is purchased.
