The Napco 5861-8 is a vacuum oven for laboratory and industrial drying, curing, and heat treatment applications requiring precise temperature control in an airless environment. The unit features a 4.5 cubic feet stainless steel chamber with adjustable shelving, double-wall insulation, and vacuum capability to 30 inches Hg. Temperature control ranges from 35°C to 200°C via front-mounted analog or digital controller with over-temperature protection. Operating on 120V, 60 Hz single-phase power at 12.5 A (1500 W), the oven measures 26″ W × 36″ D × 35.5″ H externally with an 18″ W × 24″ D × 18″ H interior. Three adjustable shelves rated at 2.6 sq. ft. per shelf accommodate parallel processing. The vacuum port is located on the rear; the vent knob is top-mounted. Shipping weight is approximately 290 lbs.
