AT19e series digital desktop vacuum ovens feature a 1.9 cubic foot easy-to-clean stainless steel chamber with a large dual-layer tempered glass safety window and small footprint. These ovens can greatly reduce drying time by maintaining a consistent vacuum level within the chamber. Every one of our vacuum ovens goes through a 2-time 24-hour vacuum leak test, and is 100% quality controlled in New Jersey or Nevada before leaving our facilities. Attention: Before initial use, run oven at 200C/400F without vacuum for 15 minutes to burn off any residue that may have been introduced during the manufacturing process. IMPORTANT! NEVER LEAVE YOUR OVEN UNATTENDED WHILE OPERATING. Across International is not responsible for any loss of material inside of the oven.
