Precise™ Controlled Atmosphere Glove Box, Labconco®

Designed to provide a leak-tight environment for work with contamination-sensitive materials

Unit is performance tested to maintain less than 5ppm oxygen levels and less than 50ppm moisture levels. Features six manual valves with 0.95cm (³/₈") compression fittings and hose barbs. Two valves on the main chamber and two on the transfer chamber are for purging and filling. The other two on the main chamber are for drying connections. The main chamber has a pressure gauge with readings from –12.7 to 12.7cm (–5 to 5") of water gauge. The transfer chamber has a pressure gauge with readings from –73.7 to 0cm (–29 to 0") of mercury.

Glove box meets Class 1 atmosphere containment conditions for oxygen leak rates per ISO 10648-2 test method. The 115V model is ETL listed with UL 3101-1/61010-1 and CAN/CSA C22.2 No. 1010.1 conformity. The 230V model is CE marked.

The unit features a dry powder, epoxy-coated steel superstructure; 0.6cm (¹/₄") thick laminated safety glass viewing window with powder-coated steel frame and neoprene gasket; and molded one-piece, medium-density, polyethylene shell. The cutout area is 67Wx31.8Hcm (26¹³/₃₂x12¹/₂") high, and the window can be easily removed for loading equipment. The space-saving inner and outer transfer chamber doors pivot upward and are counterbalanced and equipped with quick latches. The interlocking shelf and high vacuum sleeve of the interior transfer chamber is made of dry powder, epoxy-coated steel. The black, chemical-resistant phenolic core work surface is sealed to the glove box floor. Glove box includes a pressure relief valve that activates at pressure/vacuum above 15.2cm (6") or below –15.2cm (–6") of water gauge. The pressure relief valve vent has a 10.2cm (4") nominal diameter. Unit has an interior ceiling-mounted electrical duplex receptacle with 5A maximum (100/115V model) or 2A maximum (230V model) circuit load, and includes switches for the light and innermost interior electrical receptacle. Glove box is factory leak tested with a mass spectrometer while pressurized with helium at 12.7cm (5") of water gauge. No detectable leaks greater than 1x10-4 mL/sec.

Ordering information: Supplied with pair of 76.2cm (30") long, 150mil thick neoprene gloves (size 9³/₄), and a 22W fluorescent lamp with easy replacement from the top. Glove box requires supporting base, vacuum source for purging, and inert gas for filling (not included).
