The Across International AT32-316L-UL Vacuum Oven is a UL-certified laboratory vacuum oven designed for high-purity laboratory, pharmaceutical, and extraction applications. Featuring a 3.2 cubic foot chamber constructed from 316L stainless steel, this vacuum oven provides superior corrosion resistance, cleanliness, and durability compared to standard stainless steel ovens.

The AT-X series utilizes advanced 5-sided chamber heating technology, delivering exceptional temperature uniformity and rapid heating performance. Combined with 4th generation PID temperature control, this system provides highly accurate temperature regulation and efficient energy usage.

Designed for flexibility and ease of maintenance, the oven includes removable aluminum shelves, allowing operators to adjust shelf configurations or remove shelves entirely for larger samples and easier chamber cleaning.

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