Labconco™ Protector™ Combination Glove Boxes

Opening two internal valves converts the box from controlled atmosphere mode to filtered mode. Ideal for laboratories that have multiple types of glove box applications or anticipate that their applications may change in the future.

Overall Features

• Factory leak-tested—no detectable leaks greater than 1 × 10^-6mL/sec.
• LCD dual display—one shows pressure of both chambers, the other shows airflow (CFM), air changes/min. (ACM) and main chamber pressure (in. of water)
• 0.38 in. thick laminated safety glass viewing window with 36.0W × 27.6 in.H (91 × 70cm) viewing area
• Pair of neoprene gloves 0.015 in. thick, 30 in. long, size 9 3/4
• Two 8 in. ID epoxy-coated aluminum, double-grooved glove ports with neoprene gaskets
• Switches for light, blower and electrical receptacle
• Two 25-watt fluorescent lights
• Dry-powder epoxy-coated, 18 and 20 gauge steel exterior panels

Filtered Glove Box Features

• Particulate containment <20 nanograms per cubic meter (naproxen sodium surrogate)
• Fast “clean up” time—0.05 ppm average tracer gas levels or less detected during perimeter scan testing (surpasses ASHRAE 110 standards) after 5 minute dilution
• Airborne particulate cleanliness exceeds ISO Class 4 conditions and achieves ISO Class 3 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
• Mutable, audible/visual low airflow/pressure alarm

• Exceed Class 1 atmosphere containment conditions for oxygen permeation <1.67 ppm/min. per ISO 10648-2 test method
• Four manual valves with 3/8 in. compression fittings—two on the main chamber and two on the transfer chamber
• Automatic control of the main chamber pressure, main chamber evacuation and filling cycles, and transfer chamber evacuation and filling 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/visual alarm that sounds when pressure/vacuum level is outside set limits
• Three-position foot pedal (increase gas/fill, off, evacuate/decrease gas)
• 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 in. OD compression fittings for easy connection to optional gas purifier or accessory drying train
