Across International - Accu Temp Vacuum Drying Oven / Degassing Oven - 3.2 Cu Ft

An 18 in Cube: the 3.2 Cu Ft Vacuum Oven The chamber is an eighteen inch cube, which works out to 3.2 cubic feet. Heat does not come from the walls here. Three aluminium shelves each carry their own 500W heater, an in-shelf sensor and a controller. Material sits on the heat rather than waiting for the air to bring it. Shelf surfaces run 17.5 by 17.25 in and sit 4.75 in apart. That gap halves to 2.25 in with the optional stackable shelves, which doubles usable area. Each shelf takes up to 20 lb. Electrical is 1,500 W either way, drawing 13.6 A at 110V or 6.8 A at 220V. Setpoint accuracy is 1 F and uniformity holds within 5% across the chamber. It reaches 100 F in about 35 minutes and 480 F in an hour. Choosing This Across International Oven Over Its Siblings This is the middle size in the range, and the reason to pick it is throughput without a forklift. The bench model handles a sample or a small purge; the largest needs a pallet and a dedicated circuit. At 260 lb on a floor stand, this one sits between them and rolls into a lab with room for a chest freezer. Internal tubing is stainless, which is what holds a deep vacuum for months rather than weeks. An oil-filled mechanical gauge resists the shipping damage that kills dry gauges. A check valve stops pump oil crawling back into the chamber when the pump shuts down. Vacuum reaches better than 500 microns with a pump sized to the chamber. Insulation is three inches and the window is dual-layer tempered glass. Two year warranty, UL and CSA listed, with lifetime US support.
