Protector® Combination Glove Boxes
By Labconco
Protector® Combination Glove Boxes provide inlet and outlet HEPA or ULPA filtration and a leak-tight physical barrier to protect the operator from exposure to potentially hazardous materials and perform work with contamination-sensitive materials under vacuum or in an inert environment. These combination glove boxes have the ability to function as either a filtered box or a controlled atmosphere box. Opening two internal valves converts the box from controlled atmosphere mode to filtered mode. Laboratories that have multiple types of glove box applications or anticipate that their applications may change in the future are ideal users of this type of glove box. Choose between single- or double-width models with fiberglass or stainless steel liners.
All models are factory leak-tested with a mass spectrometer while pressurized with helium at 5 inches of water gauge, with no detectable leaks greater than 1 x 10-6mL/second. With dual LCD display: one regulates and displays pressure of both chambers, while the second displays airflow, air changes/minute, and main chamber pressure. Glove Boxes also feature inner and outer pivoting transfer chamber doors that are counterbalanced and equipped with quick-latches and a 3/8" thick laminated safety glass window with a viewing area of 36.0"W x 27.6"H. Dry-powder epoxy-coated, 18 and 20 gauge steel exterior panels and two 8" ID, epoxy-coated aluminum, double-grooved glove ports with neoprene gaskets. Interior right-hand side wall-mounted electrical receptacle (duplex on 100V/115V models) with 10 amp maximum and interior left-hand side wall-mounted pass-through with plug. Two 25-watt fluorescent lights. With switches for light, blower and electrical receptacle. Includes a pair of neoprene gloves, 0.015" thick, 30" long, size 9 ¾.
Filtered Glove Box Features:
- Particulate containment <20 nanograms per cubic meter
- Fast clean up time: 0.05 ppm average tracer gas levels or less detected during perimeter scan testing (surpasses ASHRAE 110 satndards) after 5 minute dilution
- Airborne particulate cleanliness (measured under positive and negative pressures per ISO 14544-1 test method) exceeds ISO Class 5 conditions (equivalent to Class 100) and achieves ISO Class 4 conditions
- Inlet and outlet particulate (HEPA or ULPA) filters to prevent contaminants from entering or leaving the glove box chamber
- Test port for challenging HEPA or ULPA filter integrity
- True Bag-In/Bag-Out Filter Disposal System for safe filter removal and replacement
- Built-in blower with speed control capable of airflow from 15 CFM to 85 CFM depending on voltage and frequency
Controlled Atmosphere Glove Box Features:
- Exceeds Class I atmosphere containment conditions for oxygen permeation <1.67 ppm/min per ISO 10648-2 test method
- Oxygen permeation <0.3 ppm/min (fiberglass-lined models) and <0.15 ppm/min (stainless steel-lined models) per ISO 10648-2
- Four manual valves – two on the main chamber and two on the transfer chamber – for evacuating, filling and added control, with 3/8" compression fittings
- Automatic control of the main chamber pressure (-5 to +5 inches of water gauge), main chamber evacuation and filling cycles (up to 499 cycles), and transfer chamber evacuation and filling cycles (up to 199 cycles)
- Regulation of vacuum/pressure between -5 and +5 inches of water gauge in the main chamber and between 0 and -29.5 inches of mercury in the transfer chamber
- Mutable, audible alarm that sounds when pressure/vacuum level is outside set limits
- Three-position foot pedal (increase gas/fill, off, evacuate/decrease gas)
- Input/output port for optional AtmosPure™ Re-Gen Gas Purifier
- Factory-installed, rear-mounted, low profile stainless steel pressure relief bubbler at 6 inches of water gauge
- Two rear-mounted inlet and outlet 3/4" OD compression fittings for easy connection to optional AtmosPure™ Re-Gen Gas Purifier or other accessory drying train
