Cascade CVO-2

The Cascade Difference

Vacuum ovens have been around for decades. Basic vacuum ovens are mass-produced and sold by many large scale laboratory equipment distributors. But there are key differences between Cascade and other inexpensive, often imported vacuum ovens:

Exceptional Temperature Control & Stability

The Cascade CVO-2 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-2 eliminate hot and cold spots, making accurate use of every inch of shelf space.

Independent Over-temp Failsafe Protection

The Cascade Sciences CVO-2 is equipped with a heating cutoff system that will automatically stop power to the heaters when the oven shelf temps exceed 200°C or 392°F. This protection system will provide peace of mind for overnight processing or unattended vacuum bake outs.

  • 5 shelves (11.5″W x 19″D) in a flexible configuration. Stack-able and removable 
  • Stable temperature control. Digital temperature readout with temp sensor INSIDE the oven
  • Bright LED lights in window for visibility of sensitive material
  • Digital vacuum gauge reads in inches of mercury
  • Simple, set-point control
  • Smooth, quarter-turn vacuum and vent valves

  • 120V (220V available)
  • Quality Tempered Rated Glass NGI-US to ANSI Z97.1.2007 156CFR/201 11 SGCC -2577 ½ UA
  • Adjustable leveling feet ensure oven sits solid and level in the workspace



  • CVO-2 Connections
  • 3/8″ Barb for Vacuum Pump
  • 1/4″ Barb for Venting (N2 Connection OK)
  • KF-25 Port for feedthroughs or MAXEVAP Connection Kit 


Agilent IDP7 Dry Scroll Pump Features



  • Oil-Free. Eliminates contamination risk. Will not smoke out exhaust, no filter required.
  • Quiet (for a vacuum pump)
  • 5.4 CFM pumping speed
  • Ultimate vacuum: 2 x 10-2 Torr
  • 120V or 220V / 1ph power – flexible configuration

  • Powerful enough to accommodate a second vacuum pump

Need A Complete CVO-2 Vacuum Package?

The CVO-2 STANDARD Package is an ideal package for vacuum drying or purging requiring a steady, gentle, non-turbulent purge with an oil-free scroll pump.

The CVO-2 PRO Package is ideal for higher thru-put, faster purge times pulling deeper vacuum with our MAXEVAP connection kit and the IDP7, oil-free scroll pump.


CVO-2 Standard Package Includes:

  • CVO-2 vacuum oven
  • 5 aluminum shelves in 1″, 2″ and 3″ heights for varied configurations
  • Agilent IDP7, 5.4CFM dry scroll pump 


CVO-2 PRO Package Includes:

  • CVO-2 vacuum oven
  • 5 aluminum shelves in 1″, 2″ and 3″ heights for varied configurations
  • Agilent IDP7, 5.4CFM dry scroll pump 
  • MAXEVAP vacuum oven to pump connection kit. This special connection kit optimizes flow rates with a large 1″ dia exit path out of oven, large, vacuum rated 1″ diameter lines, a large 1″ diameter vacuum valve and into the 1″ diameter vacuum pump inlet. At no time is the out-gas load restricted or flow reduced. Also includes the KF-25 hardware.


NRTL Certification #U8 170464972 077. No Extra cost.

The CVO-2 Vacuum Oven comes certified by the Nationally Recognized Test Lab, TUV. This certification is a requirement by many municipalities.CAN/CSA-C22.2 No. 61010-1:2012+UPD No. 1:2015-07 + UPD No. 2:2016-04CAN/CSA-C22.2 No. 61010-2-010:2015UL 61010-1:2012/R:2016-04UL 61010-2-010:2015EN 61010-1:2010EN 61010-2-010:2014

Rigorous Quality Assurance in an ISO Certified, USA Manufacturing FacilityCascade 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 integrityElectrical & mechanical safety is thoroughly tested in compliance with TUV requirementsFunctional 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

Digital Vacuum Gauge

The digital vacuum gauge installed on the CVO-2 is factory default set to read in inches of mercury (“Hg) with a scale of 0 – 29.9”Hg. Change the unit of vacuum measurement to read in a wide variety of units from mmHg, bar psi, kPa, cm2, mmH20. Zero out the vacuum gauge to calibrate for just above sea level adjustments.


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 1/4″ rear vent barb. The maximum backfill pressure is 15psi at the inlet. In an overpressure situation, a simple, built-in safety relief allows gasses to escape via a spring loaded tempered window.


Flexible Pumping / Feedthru Connection Ports

The CVO-2 ovens offer two different vacuum oven connection points. The standard connection is a 3/8″ 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 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. 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 feedthroughs, or monitoring sensors inside the vacuum chamber during processing.
