Cascade CVO-2 Vacuum Purge Oven

Cascade’s CVO-2 Benchtop Vacuum Oven for Temperature Sensitive Products
Cascade’s Model CVO-2 offers incredible temperature stability for vacuum drying and purging of pharmaceuticals, botanicals, slurries, or any temperature sensitive material. This vacuum oven liberates solvents, water, and other unwanted compounds. It’s ideal for small batch, R&D and laboratory environments.

Processing Temperature Sensitive Material? The CVO-2 comes in both low temp & high temp versions.

Be sure to get the low temp CVO-2 version that has excellent temperature uniformity for temperature sensitive products such as pharmaceuticals, slurries or any product that can be damaged or destroyed by temperature fluctuations.

Low Temperature Processing Range:  26°F to 250°F (121°C)
Temperature Uniformity: +/- 1.5°F @ 105°F (40.5°C)
Temperature Stability: +/- 0.4°F @ 105°F(40.5°C)

High Temperature Processing Range:  Up to  428°F / 220°C
Temperature Uniformity: +/- 6.5% of setpoint

At time of order we will verify the high / low temp version best suited to your requirements.

Need A Complete Vacuum Drying or Purge System?

Cascade has taken the guess work out of pairing the right vacuum oven with the proper pump. We offer two complete CVO-2 vacuum oven packages that have everything you need to begin vacuum drying. Both systems feature clean, quiet, Agilent oil-free scroll pumps.

The CVO-2 STANDARD Package is an ideal benchtop set up for vacuum drying or purging temp sensitive material requiring a steady, gentle, non-turbulent purge.

The CVO-2 PRO Package is ideal for higher thru-put, faster purge times pulling deeper vacuum.
