The Precision Extraction Difference:

Exceptional Temperature Control & Stability
The Precision Extraction vacuum ovens use 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 oven eliminate hot and cold spots, making accurate use of every inch of shelf space.

Read Temperature in degrees Celcius or Fahrenheit

• Read Vacuum in Torr or Inches of Mercury
• Energize Vacuum Pump From Oven Control Panel
• Turn the vacuum pump off and on from the oven control panel.  No more reaching around, behind, beside to turn the vacuum pump off an on.  Vacuum pump plugs directly into the back of the oven’s auxiliary outlet.

Independent Overtemp Failsafe Protection
The Precision Extraction vacuum ovens are equipped with a heating cutoff system that will automatically stop power to the heaters when the oven shelf temps exceed 392°F or 200°C. This protection system will provide peace of mind for overnight processing or unattended vacuum bake outs.

Log Temperature & Vacuum With Data Port
The vacuum ovens feature a rear-mounted data port which outputs a digital log line once per minute. Viewing/logging this data requires terminal emulator software such as the open source (BSD License) emulator Tera Term.

NRTL Certification #U8 170464972 077. No Extra cost.
The vacuum ovens come certified by the Nationally Recognized Test Lab, TUV. This certification is a requirement by many municipalities and is often an extra charge on low-cost ovens.

• Rigorous Quality Assurance in an ISO Certified, USA Manufacturing Facility
• Manufactured in Oregon, USA
• 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 
• 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 ¼” 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 ovens offer two different vacuum oven connection points. The standard connection is a 3/8th 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 MAX EVAP connection kit. The MAX EVAP connection kit secures to the oven’s rear 1” dia KF-25 port located on the back center of the chamber. The MAX EVAP 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 feed-throughs, or monitoring sensors inside the vacuum chamber during processing.

Door Gasket Options – Ideal For Your Process
Precision Extraction's vacuum ovens come standard with a solvent resistant BUNA door gasket. For higher temp applications, we offer a cured Silicone gasket as well. Gaskets will eventually wear out. It’s ideal to keep a few spares on hand.

CVO-5: Touchscreen LED Smart Controller
The controller is a flat panel touch screen with built-in, controls that minimize temperature overshoot. When the oven door is open, the controller will wait and not aggressively call for heat to attempt to keep the oven interior stable.  When the oven is being vented, the controller will pause as to not over-react and overshoot temperature during this temporary event.
