Cascade CVO-2 Vacuum Oven

Cascade CVO-2 Vacuum Oven

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 in small batch, R&D and lab environments.NRTL Certified.

Operating Range: Ambient +10C to 150C (Ambient +18F to 300F)

Benchtop Size:1.47 Cubic Ft (47.2L) 12W x 20D x 12H

Exceptional Temperature Control & Stability

The CVO-2 uses a unique control logic not found in most lab grade vacuum ovens. The temperature probe isINSIDE 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 CVO-2 is equipped with a heating cutoff system that will automatically stop power to the heaters when the oven shelf temps exceed 200C or 392F. This protection system will provide peace of mind for overnight processing or unattended vacuum bake outs.

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 29.9Hg. 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. TheMAXEVAP connection kitsecures to the ovens 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. 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!

Door Gasket Options Ideal For Your Process

Vacuum ovens come standard with aHigh Temp Silicone Door Gasket. We also offer aSolvent resistant BUNA 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. Its ideal to keep a few spares on hand.
