Category Vacuum Ovens
Manufacturer Across International

AT19-500C series digital desktop 500C 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.


  • All stainless steel internal tubing & compression fittings provides higher ultimate vacuum, holds vacuum 10 times longer, and require minimum maintenance.
  • Oil-filled mechanical vacuum gauge provides more accurate reading, longer gauge life and minimizes shipping damage.
  • All stainless steel vacuum and vent valves gives you cleaner connection, more accurate control and long term durability.
  • New 5 sided heating technology and aluminum shelves provide excellent temperature uniformity and faster heating rates (25% faster in our lab test).
  • Adjustable gas back fill capability with needle valve and vent port.
  • 3" thermal insulation prevents heat loss and minimizes the enclosures outer surface temperature.
  • Easy-to-clean stainless steel interior for exceptional durability and ease of maintenance.
  • Built-in alarm alerts you when oven has been shut down by safety circuitry due to out of range temperature.
  • All ovens shipped from our New Jersey or Nevada location for quick delivery, and come with two year warranty and lifetime US-based parts and service support.
  • Guaranteed US based phone and email assistance within 30 minutes from our engineers.

FIVE STAINLESS STEEL SHELVES INCLUDED WITH OVEN PURCHASE. SST (stainless steel) tubing refers to internal tubing and compression. external tubing not included. Water recirculation required to keep door gasket cold.
