The Across International AT09-UL Vacuum Oven is a UL-certified laboratory vacuum oven designed for high-precision drying, curing, degassing, and solvent removal applications. Featuring a 0.9 cubic foot stainless steel chamber, this compact desktop vacuum oven provides reliable vacuum performance while maintaining a small footprint ideal for laboratory workspaces.

Equipped with advanced 5-sided pad heating technology, thermal-conductive aluminum shelves, and a 4th generation PID temperature controller, the AT09-UL delivers excellent temperature uniformity, faster heating rates, and precise temperature control. The system also includes all stainless steel internal tubing and compression fittings, ensuring stronger vacuum integrity and long-term reliability.

Each oven undergoes two separate 24-hour vacuum leak tests and is 100% quality controlled in New Jersey or Nevada before shipment to ensure dependable performance.
