The TVO-2 STANDARD Package is a 2 cubic foot, benchtop vacuum oven paired with a clean, oil-free scroll pump. This package is an ideal benchtop set up for vacuum drying or purging temp sensitive material requiring a steady, gentle, non-turbulent purge. This complete system will liberate solvents, water or other unwanted compounds in a small batch, R&D, laboratory environments.

TVO-2 STANDARD Package Includes:

  • Cascade Sciences TVO-2 vacuum oven
  • 5 stackable, flexible aluminum shelves in 1", 2" and 3" heights
  • Agilent IDP3, 2.1CFM dry scroll pump
  • Vacuum oven to pump connection kit. 3/8th diameter vacuum rated tubing and KF hardware.

  • Adjustable "gas ballast" allows for better solvent tolerance / ingestion
  • Maintenance requires the replacement of a single "tip seal". Low cost of ownership.

Exceptional Temperature Control & Stability

The Cascade TVO-2 uses 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 TVO-2 eliminate hot and cold spots, making accurate use of every inch of shelf space.

Independent Overtemp Failsafe Protection

The Cascade Sciences TVO-2 is 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.

NRTL Certification #U8 170464972 077. No Extra cost.

The TVO-2 Vacuum Oven comes certified by the Nationally Recognized Test Lab, TUV. This certification is a requirement by many municipalities.

Rigorous Quality Assurance in an ISO Certified, USA Manufacturing Facility

Cascade Sciences manufactures our ovens in Oregon, USA. We are proud of our ISO 9001 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

Digital Vacuum Gauge

The digital vacuum gauge installed on the TVO-2 is factory default set to read in inches of mercury ("Hg) with a scale of 0 - 29.9"Hg. 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.

Log Temperature & Vacuum With Data Port

The TVO-2 features 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.

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. 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 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. This KF-25 port can also be used to run temperature feedthrus, 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. Cascade's stackable shelf design makes the most of this opportunity by making the chamber longer and narrower, rather than square and supplies stackable shelfs 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!

ANSI Rated Tempered Glass + USA Made Steel

Cascade ovens are made in Oregon, USA with high quality materials. Our glass is NGI-USA Tempered and certified to ANSI Z97.1.2007 16CFR / 201 11. Our door handles are rugged brushed steel, not plastic. Our vacuum vessels are constructed with American made steel. We've tried lower cost, imported steel, but over time, vacuum chambers made of lesser quality/lower tolerance material cannot withstand the flex and pressure changes of vacuum pumping/venting/purging. This can deteriorate vacuum integrity and the oven will lose its ability to hold vacuum.
