Cascade CVO-5 Vacuum Purge Oven

CVO-5 Vacuum Purge Oven
Cascade’s Model CVO-5 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-5 comes in both low temp & high temp versions.

Be sure to get the low temp CVO-5 version that has excellent temperature uniformity for 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.
