Vertical Storage System for Non-Stacking Materials

Standard Features

  • A Stainless Steel-Framed Doors with One-Piece Gasket
    "e"-profile gasket mechanically attached to stainless steel reinforcement frame to prevent outgassing adhesives; one-piece design won’t slough or separate
  • B Grounding Terminals
    Standard on static-dissipative PVC chambers to prevent electro-static discharge (ESD)
  • C Plenum Chamber
    Located in rear of cabinet, plenum ensures uniform flow of nitrogen gas to all chambers; minimizes moisture migration
  • D Automatic RB® Valve
    Prevents overpressure; acts as a check valve (one included per chamber)
  • E Stainless Steel Wire Racks
    Supports carrier reels of specified quantity and diameter
  • F Grounded Door Latch
    Prevents ESD damage to stored parts (standard on static-dissipative PVC cabinets)
  • G Stainless Steel Hinges
    Non-contaminating hinges contribute to a long service life under heavy use

Optional Features

  • 1 Dual Purge™ System
    Provides a variable flow of nitrogen purge gas: high to recover set point, low to conserve nitrogen
  • 2 NitroWatch® RH Controller
    Monitors internal humidity; activates a high-flow purge when RH climbs above set point
  • 3 Door Sensor Switches
    Activate high-flow purge when a door opens to recover RH set point
  • 4 Stand with Casters
    Powder-coated or 304 stainless steel; 4” or 12” high; casters available

Not Shown: Flowmeter included for manual regulation of flow rate (choose Dual Purge/NitroWatch systems for automated control); Nitrogen generator provides an uninterrupted supply of nitrogen up to 99% pure to eliminate reliance on bulky canisters.

Features and Benefits

Versatile Configurations

Vertical Storage desiccator cabinets include air-tight, non-contaminating seals, a complete line of standardized accessories, and the most advanced humidity control system available anywhere, as well as self-balancing nozzles that safely neutralize static charges on non-conductive surfaces.

Slide-Out Drawers

Stainless steel trays mounted on non-contaminating slides allow full access to drawer contents. Each drawer accommodates two rows of non-stacking materials, such as PC boards, glass plates, reels or slides.

Adjustable Stainless Steel Racks

304 stainless steel adjustable rack securely holds non-stacking materials such as PC board, glass plates, slides and reels. Stainless steel racks won't produce contaminants like chrome-plated steel designs.

Automatic Relief/Bleed Valve

Terra's Automatic Relief/Bleed (RB) Valve opens up at 0.01 PSI, relieving overpressure that could damage desiccators; also works as a check valve to prevent influx of room air.

  • Laboratory Nitrogen Generator
    Terra’s Nitrogen Generators provide a continuous, reliable supply of clean, dry nitrogen up to 99% pure to eliminate dependence on bulky canisters to operate desiccators and glove boxes.
  • Universal Adjustable Base Stands for Desiccator Cabinets and Cleanroom Equipment
    Stainless steel or powder-coated steel base stands easily adjust to fit cabinets, desiccators and cleanroom equipment of any size or shape. Stands raises equipment to ergonomic height to ease disinfection and sample monitoring. BioSafe design suitable for any cleanroom or lab environment.
  • Desiccator Cabinet Ionizing Module
    Ionizing modules are available for desiccator cabinets, glove boxes and other enclosures to ensure static-safe storage and processing (shown: ionizing unit on 2-chamber desiccator)
  • Dual Purge™ and NitroWatch™ Work Together to Fully Automate RH Control
    Terra's Dual Purge™ and NitroWatch™ operate in tandem to precisely and automatically control the flow of nitrogen and maintain a preset humidity level (from ambient to 0% ± 1.5% RH), no matter how operating conditions may change.
  • Data Logging with 113,000 Readings at User Defined Intervals
    Terra's Smart® IsoDry® Nitro-Watch™ logs RH, temp, door open/close, purge on/off, and sensor removal/attachment. The max data file size is roughly 4 MB or 113,000 readings. This is approximately 32 hours of data when logging at 1 second intervals, 2 weeks at 10 second intervals, 6 weeks at 30 second intervals, or 12 weeks at 1 minute intervals. When the system reaches the 4MB limit, data begins to wrap, overwriting oldest data with new.
  • Plug & Play Data Logging
    Plug in a USB flash drive to your Smart® IsoDry® Nitro-Watch™ to transfer data in .CSV format. No software required.
