The Ai AccuTemp 1.9 cu ft vacuum ovens are UL/CSA certified, this certification is required by many municipalities, and it also provides a higher standard of equipment safety and lifespan. Also come standard is the secondary over-temp protection dial, all stainless steel tubing/compression fittings, stainless steel vacuum/vent valve, oil-filled vacuum gauge, 5 sided pad heating technology and two year warranty. The thermal-conductive aluminum shelves provide excellent temperature uniformity inside the chamber, while our 3rd gen LCD low proportional gain temperature controllers keep your oven temperature within +/- 1°F accuracy, in either °F or °C.

AccuTemp-19 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.

Attention: Before initial use, run oven at 400°F 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.


  • 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.
  • 5 sided pad 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.
  • 3rd gen LCD low proportional gain temperature controllers keep your oven temperature within +/- 1°F accuracy, in either °F or °C
  • Best choice for the curing and converting of oil extracts. With deep vacuum level, they can operate at temperatures which allow the degassing/purging process to occur rapidly, thus increase productivity and allow for the production of superior quality products with minimal processing time.
  • Dual layer observation window with 1/2" tempered safety glass.
  • 3" thermal insulation prevents heat loss and minimizes the enclosure's 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 New Jersey or Nevada for quick delivery, and come with two year warranty and lifetime US-based parts and service support.
