The Across International AT32-UL Vacuum Oven is a UL-certified laboratory vacuum oven designed for high-precision drying, curing, degassing, and solvent removal applications. With a 3.2 cubic foot stainless steel chamber, this advanced vacuum oven delivers exceptional temperature uniformity, rapid heating rates, and superior vacuum performance.

Unlike traditional vacuum ovens, the AT32-UL features individually heated aluminum shelves with integrated temperature sensors and controllers, providing extremely accurate and consistent heating throughout the chamber. Combined with advanced 4th generation low proportional gain temperature control technology, this system ensures fast ramp times, minimal heat loss, and improved energy efficiency.

The UL certification meets strict safety requirements required by many municipalities, laboratories, and industrial facilities, ensuring a higher standard of equipment safety, reliability, and lifespan.

Each oven undergoes two separate 24-hour vacuum leak tests and is fully quality controlled in New Jersey or Nevada before shipment.
