  • Exceptional Temperature Control & Stability
    The Cascade CVO-5 uses a unique control logic not found in most lab grade vacuum ovens. The temperature probe is INSIDE the oven, which minimizes temperature overshoot and delivers best-in-class temperature stability and uniformity particularly in the low temperature ranges. Accurate, stable temps throughout the CVO-5 eliminate hot and cold spots, making accurate use of every inch of shelf space.

  •  Touchscreen Smart Controller

    The CVO-5 controller is a flat panel touch screen with controls that minimize temperature overshoot. When the oven door is open, the controller will wait and not aggressively call for heat to attempt to keep the oven interior stable.  When the oven is being vented, the controller will pause as to not over-react and overshoot temperature during this temporary event.

    • Read Temperature in degrees Celsius or Fahrenheit
    • Read Vacuum in Torr, Bar or Inches of Mercury
  • Independent Overtemp Failsafe Protection
    The Cascade Sciences CVO-5 is equipped with a heating cutoff system that will automatically stop power to the heaters when the oven shelf temps exceed 340°F or 170°C. This protection system will provide peace of mind for overnight processing or unattended vacuum bake outs.

  • NRTL Certification #U8 170464972 077. No Extra cost. 

The CVO-5 Vacuum Oven comes certified by the Nationally Recognized Test Lab, TUV. This certification is a requirement by many municipalities and is often an extra charge on low cost ovens.

  • Rigorous Quality Assurance in an ISO Certified, USA Manufacturing Facility

Cascade Sciences manufactures our ovens in Oregon, USA. We are proud of our ISO 9001 Certification/Accreditation. Each oven completes a series of quality assurance procedures before shipment.

  • Chambers are vacuum tested after welding for vacuum integrity
  • Electrical & mechanical safety is thoroughly tested in compliance with TUV requirements
  • Functional testing verifies user settable items consistent with most lab protocols/usage models
  • Temperature verification includes calibration & temp chamber uniformity following ASTM standards
  • Units are cleaned and packed in ISTA tested, certified packaging materials 
  • Equipped for Inert Gas Backfill. Built-In Safety Relief

Introduce inert gasses such as nitrogen, argon, helium, etc. as part of your process via the ¼” rear vent barb. The maximum backfill flow pressure is 15 psi at the delivery port. In an overpressure situation, a simple, built-in safety relief allows gasses to escape via a spring loaded tempered window. This is not a positive pressure chamber.

  • Flexible Pumping / Feedthru Connection Ports

The CVO-5 ovens offer two different vacuum oven connection points. The standard connection is a 3/8th dia barb located at the rear of the oven. It is connected to the vacuum valve level on the front control panel.  For even faster evaporation, purging or drying consider upgrading to the optional MAXEVAP connection kit. The MAXEVAP connection kit secures to the oven’s rear 1” dia KF-25 port located on the back center of the chamber and can be installed anytime. The MAXEVAP connection never reduces flow by continuing with 1” diameter vacuum rated clear lines, a 1” dia KF-25 side mounted vacuum valve and KF-25 fittings and hardware. This KF-25 port can also be used to run temperature feedthrus, or monitoring sensors inside the vacuum chamber during processing.

  • Ergonomically Designed, Easy Quarter-Turn Valves

For anyone that has struggled with consistently turning the small, round, low-quality vacuum/vent valves, relief is in sight. You will love our large, quarter-turn vacuum/vent valves. Your wrists will thank you!

  • ANSI Rated Tempered Glass + USA Made Steel

Cascade ovens are made in Oregon, USA with high quality materials. Our glass is NGI-USA Tempered and certified to ANSI Z97.1.2007  16CFR / 201 11. Our door handles are rugged brushed steel, not plastic. Our vacuum vessels are constructed with American made steel. We’ve tried lower cost, imported steel. But over time, vacuum chambers made of lesser quality/lower tolerance material cannot withstand the flex and pressure changes of vacuum pumping/venting/purging. This can deteriorate vacuum integrity and the oven will lose its ability to hold vacuum.
