The Across International 7.5 Cu Ft 5-Sided Heating Vacuum Oven is a high-capacity industrial laboratory vacuum oven designed for large-scale drying, curing, degassing, and solvent removal applications. With a 7.5 cubic foot stainless steel chamber and up to 18 shelf capacity, this vacuum oven allows laboratories and extraction facilities to process large production batches with excellent efficiency and temperature uniformity.

Featuring advanced 5-sided chamber heating technology, this oven provides uniform heating across the entire chamber while minimizing cold spots. Combined with a 4th generation PID temperature controller, the system delivers precise temperature control, faster heating performance, and improved energy efficiency.

Every Across International vacuum oven undergoes two separate 24-hour vacuum leak tests and is quality controlled in New Jersey or Nevada before shipment to ensure reliable long-term operation.
