Smart® Glovebox; Static Dissipative PVC, 26" W x 20" D x 18" H, 2 Glove Ports, 120/240 V
  • ISO 7
  • Smart® gas-purge glove box automates low-humidity control down to 0% RH
  • Ideal for moisture-sensitive materials: microelectronics, medical devices, pharmaceutical powders
  • Gas control system auto-adjusts nitrogen purge to maintain sub-ambient humidity set point
  • Fast-acting and economical; maintains below 10% RH with 78% less nitrogen than manual flow meter
  • Fully integrated turnkey system takes only a few minutes to install and program
  • Smart® controlled atmosphere glove box isolator features automated RH control that toggles nitrogen inflow (binary on/off) for fast setpoint response.
  • Mini LED display and built-in RH sensor simplifies installation. Operation requires only one gas line, one low voltage power connection, and a pair of gloves.
  • UL-listed Smart® control module is designed and built to the highest standards required by defense and semiconductor industries for long-term reliability and protection against damage, injuries, and electrical hazards.
  • Chamber Design:
  • NOTE: ESD-sensitive applications: grounding is not standard, choose static-control options to protect sensitive materials against ESD.
  • Static-dissipative PVC (SD-PVC) design offers several benefits:
  •        Bonded dissipative layers resist abrasion and retains surface resistivity of 106 - 108 ohms/square indefinitely (unlike spray-on coatings that can wear off after a few years).
  •        Eliminates static-cling of dust particles to help maintain clean surfaces.
  •        Easy-to-clean with increased chemical resistance to isopropyl alcohol and other cleaning agents.
  • Innovative wall fusing technology with continuous seams bonds walls together into a single rigid enclosure for easy cleaning and maximum protection against chemical splashes and spills.
  • Removable back wall allows transfer of large process equipment that can't fit through openings.
  • Access doors mounted on left and right side feature stainless steel frames and hardware to increase structural rigidity for a longer service life.
  • Santoprene® “e”-shape non-outgassing rubber gasket installed to door frames firmly compresses for a tighter seal. Resilient rubber maintains its shape after compression and won't flatten, warp, crack, or degrade like ordinary foam gasket. Gasket is also mechanically attached to the door frame to avoid adhesive failure common with gasket tapes.
  • Round ABS plastic glove ports provide a wide range of motion, and compatibility with numerous glove types. ABS Plastic offers excellent tensile strength and stiffness. Resists heat, most oils, acids, and alkalis.
  • Automatic relief/bleed (RB) valves continuously bleed off excess internal gas in only one direction. Helps maintain a slight positive pressure inside the glove box without allowing contaminants inside.
  • Requires gloves (sold separately): available as one-piece, fully dipped gloves or two-piece glove and sleeve combinations with Glove-Under-Sleeve (GUS) connectors to allow fast, inexpensive glove replacement.
  • Optional Accessories:
  • Inert gas airlock: minimize nitrogen loss and contamination inflow when materials are passed through the glove box. The airlock is connected to an inert gas line to purge out ambient air before the inside door is opened to allow materials to transfer into or out of the main chamber.
  • Nitrogen generator: provides a continuous, reliable supply of pure, dry nitrogen to eliminate dependence on bulky canisters.
  • ErgoHeight™ automatic height adjusting table: perfect for workstations holding heavy or fragile equipment that require frequent height adjustment.
  • NOTE: Glove box is designed for positive-pressure operation and is therefore not tested as a hermetically sealed chamber, and is not designed for containment of hazardous materials.

Positive Pressure Isolation vs. Biohazard Containment
Polycarbonate Smart Glovebox with Air Lock, Shown in Use

Terra glove boxes are designed as positive-pressure isolation chambers that operate with a continuous inflow of process gas and include bleed valves to relieve overpressures. Unless specified, they are not designed as low-leak or air-tight containment chambers, nor should they be used with hazardous substances that require air-tight seals. In containment applications, a glove box should typically be operated under continuous negative pressure, via a ventilated duct, so that any small leaks do not contaminate the operator or the environment.

Terra Universal's Smart™ Glovebox automatically maintains a low-humidity environment to protect moisture-sensitive parts.

Its quick-response feedback system continuously monitors the chamber’s relative humidity level and indicates the measured value on a bright LED display.

The minute the %RH climbs above a set point value, the Smart™ Glovebox activates a flow of dry nitrogen for as long as needed to restore the desired humidity level.

This fast-acting control system economizes on nitrogen use. Comparison testing reveals that the Smart™ Glovebox maintaining a 10% RH level uses only 22% of the nitrogen required by a flowmeter-based system of identical size. More importantly, this automated operation maintains the integrity of sensitive parts, such as semiconductor chips, medical devices or pharmaceutical powders, without operator monitoring.

For optimal performance, select a pass-through air lock, which functions as a transfer buffer zone.

The Smart™ Glovebox includes a control system, Automatic RB valve, and inlet/outlet fittings for 0.25" (6 mm)-diameter gas line. A removable back wall allows introduction of large process equipment. Select air lock, work surface and gloves separately.

Automatic Nitrogen-Purged Stainless Steel Glove Box for Inert Environment

Terra’s Smart® glove box includes a nitrogen control module that maintains a low-humidity set point to protect oxygen- and moisture-sensitive parts; takes only seconds to program. An optional inert gas airlock minimizes nitrogen loss and contamination inflow from materials transferred through the glovebox.

Stainless Steel Inert Glove Box for Medical Devices

Smart® stainless steel glovebox is suitable for heavy-duty, sterile, and ESD-safe applications. CleanSeam™ design features fully-welded single piece enclosure with smooth and seamless interiors to eliminate hard-to-clean cracks and crevices that can harbor contaminants.

Acrylic Inert Glove Box for Moisture-Sensitive Materials

Smart® plastic glove box isolator with low cost Plexiglass acrylic offers durability (17x impact resistance of glass), superior clarity, and UV resistance (won't yellow from exposure to sun).

Polypropylene Inert Glove Box for Corrosive Chemicals

Smart® automatic inert glove box isolator with opaque white polypropylene offers the best resistance to a wide range of corrosive acids, solvents, and disinfectants. The solid frame and walls feature continuous-seam welds for easy cleaning and maximum protection against chemical splashes and spills.

ESD-Safe Inert Glove Box for Microelectronics

Static-dissipative PVC (SD-PVC) construction dissipates electro-static charges and eliminates static-cling of dust particles to help maintain clean surfaces. Bonded dissipative layers resist abrasion and retains surface resistivity of 106 - 108 ohms/square longer than spray-on coatings that can wear off after a few years. Easy to clean with increased chemical resistance to isopropyl alcohol and other cleaning agents.

Polycarbonate Inert Glove Box for Pharmaceutical Packaging

Smart® inert glove box isolator with Lexan polycarbonate offers visual clarity plus several benefits over acrylic. Superior durability cracks less easily with 250x the impact resistance of glass, 15x the impact resistance of acrylic. Chemical resistant formula withstands many cleaning agents such as isopropyl alcohol. Increased thermal resistance (115–130 °C / 239–266 °F) helps withstand repeated steam sterilization.

UL-Listed Smart® Module for Long-Term Reliability

The Smart® module is UL-listed and built to the highest standards required by defense and semiconductor industries for long-term reliability. The compact controller includes an LED display and sensor to eliminate the need for external control boxes. Installation is simple, requiring only one gas and one low voltage power connection.

External Fluorescent Illuminator

Light fixture mounted outside the glovebox illuminates the interior and is easy to access. The hinged cover lifts up for light bulb maintenance or replacement.

High Caliber Hardware

Seemingly small details like latches, ports, glides and hinges are often overlooked or ignored by other manufacturers, and later become the point of costly recurring maintenance or equipment failure. Terra’s products are made of long lasting, cleanroom compatible, top tier hardware. Individual components are carefully designed and rigorously tested to guarantee the highest quality, durability, and craftsmanship.
