250C UL Certified 3.2 CF Vacuum Oven w/ 3 Shelves & SST Tubing 220V

SST (stainless steel) tubing refers to internal tubing and compression. external tubing not included. Introducing the new UL certified 3.2. cu ft vacuum ovens, 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, stainless steel tubing, stainless steel vacuum & vent valve, oil-filled vacuum gauge, and two year warranty. With our new internal shelf heating technology, each shelf in these ovens has its own heater, in-shelf temperature sensor and temperature controller, together with great thermal-conductive aluminum and our new low proportional controller technologies, the result is perfect uniformity, accurate temperature, super-fast heating rates, minimum heat loss/exterior temperature and very low power consumption.
