Need A Complete Vacuum Drying or Purge Package?

Cascade has taken the guess work out of pairing the right vacuum oven with the proper pump. We offer two complete CVO-2-HT Vacuum Oven Packages that have everything you need to begin vacuum drying. Both packages feature clean, quiet, Agilent oil-free scroll pumps.
  • CVO-2-HT STANDARD Package is an ideal benchtop set up for vacuum drying or purging temp sensitive material requiring a steady, gentle, non-turbulent purge.
  • CVO-2-HT PRO Package is ideal for higher thru-put, faster purge times, and pulling deeper vacuum.

Cascade Sciences - CVO-2-HT - CVO-2 High Temp Vacuum Purge Oven - Watlow Controller

  • Item #: 16053628
  • MFR SKU: CVO-2-HT
Technical Specs
  • Product advantages: 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.
  • 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. 2:2016-04
  • CAN/CSA-C22.2 No. 61010-2-010:2015
  • UL 61010-1:2012/R:2016-04
  • UL 61010-2-010:2015
  • EN 61010-1:2010
  • EN 61010-2-010:2014
  • 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
  • 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 mm. Hg, bar psi, k. Pa, 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. 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.
  • Stackable Shelf Design For Maximum Temperature Conduction. Under vacuum, there is no air inside a vacuum oven. Temperatures are achieved by a process of conduction and radiation to move temperatures into the product inside the oven. Cascade’s stackable shelf design makes the most of this opportunity by making the chamber longer and narrower, rather than square and supplies stackable shelves in multiple height configurations to allow for the fastest, most uniform transfer of heat.
  • 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.
  • Door Gasket Options - Ideal For Your Process. Cascade’s vacuum ovens come standard with a solvent resistant BUNA door gasket. For higher temp applications, we offer a cured Silicone gasketas well. Ask us about the variety of door gaskets we can supply based on your application: Silicone, BUNA, Viton, Fluorosilicone. Gaskets will eventually wear out. It’s ideal to keep a few spares on hand.
