316L SST 250C UL Certified 7.5 CF Vacuum Oven w/ 5 Shelves & SST Tubing

316L SST 250C UL Certified 7.5 CF Vacuum Oven w/ 5 Shelves & SST Tubing

SST (stainless steel) tubing refers to internal tubing and compression. external tubing not included.

Introducing the new UL certified 5-shelf 7.5 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 lab 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.

Every one of our vacuum drying ovens goes through a 2-time 24-hour vacuum leak test, and is quality controlled in New Jersey or Nevada before leaving our warehouses.

  • UL certified.
  • New KF25 inlet filter keeps your oven clean at all time (included with oven purchase).
  • All stainless steel internal tubing 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.
  • Five aluminum heating shelves with individual in-shelf temperature sensor, heater and digital temperature controller.
  • 4th gen low proportional gain temperature controllers keep your oven temperature accurate.
  • 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 3/4" 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.
  • A vacuum environment lowers the boiling point (great for processing heat sensitive materials) and reduces drying time for materials like paste or powder which cannot otherwise be easily dried.
  • Built-in alarm alerts you when oven has been shut down by safety circuitry due to out of range temperature.
  • Built-in swivel casters with leveling feet.
  • For improved temperature ramping, run the auto-tune procedure as outlined in the manual.
  • All ovens shipped from our New Jersey or Nevada location for quick delivery.
  • 2-year warranty and lifetime US-based parts and service support.
  • Guaranteed US based phone and email assistance from an Ai support engineer within 30 minutes.
