Cascade CVO-5 STANDARD Package

Cascade’s CVO-5 STANDARD Package
Our CVO-5, 5 cubic ft vacuum oven is connected to the oil-free, rugged, Welch CB2052 diaphragm pump. Model CB2052 vacuum pump is a private label version of Welch’s 2052B-01. The vacuum pump interior is made of solvent resistant, PTFE diaphragms.

The CVO-5 vacuum oven offers incredible temperature stability for vacuum drying and purging of pharmaceuticals, botanicals, slurries, or any temperature sensitive material. This vacuum oven will liberate solvents, water or other unwanted compounds in a small batch, R&D, laboratory environments.

Both oven and pump can run off a single dedicated 120V / 1ph / 20 AMP circuit.

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.
