VWR Signature High-Performance Horizontal Air Flow, Two-Door Oven

  • 1690 floor model
  • Temperature range: 40°C to 260°C
  • 34.4 cu. ft. capacity
  • 90-day warranty

VWR Signature High-Performance Horizontal Air Flow OvensFloor Model, Two-Door is reliable and dependable. It features true horizontal airflow design, programmable 24-step ramp and soak controller, Type-304 stainless-steel interior and exterior with a durable, powder-coated finish, three-inch intake and exhaust ports, and it’s equipped with adjustable stainless-steel shelves.

Horizontal airflow is created using a turbo blower that re-circulates air over the heating element, providing fast heat-up and recovery times, and ensuring a more rapid and efficient rate of drying. By forcing continuously warmed air into the chamber, the turbo blower assures uniform heating across all shelves and to every area of the chamber, eliminating concerns of obstructed air, regardless of how the shelves are loaded.

The Watlow microprocessor-based controller provides 24-step ramp and soak capability to an accuracy of 0.1°C. Other ramping operations include ramp-rate or time-based programming, guaranteed soak deviation, program looping, and program status selection after power outages. Easy, non-ramping set point operation is also available. Temperature range: 40 to 260°C (104 to 500°F).

To maintain temperature uniformity and stop heat loss, an 8.9cm (31/2") thick, double-layer insulating barrier of high-density alumina silicate and high-temperature fiberglass wraps around all five sides of the chamber. A high temperature silicone rubber door seal eliminates air leakage. In addition, the door latch and hinges are user-adjustable to maintain a better seal as metal expands and contracts over the life of the oven.

The independent over-temperature safety is user-adjustable and protects the unit against damage to contents and burnout in the unlikely event that the main controller fails. The sealed membrane touch-pad control panel guards against any harm to the electronics. Stainless steel interior and exterior provide maximum corrosion resistance.

All of our equipment is used and reconditioned. Our technicians test ovens using a calibrated digital chart recorder to verify the accuracy of temperature controls and readouts and run the unit under vacuum to ensure chamber integrity. We typically leave an oven under vacuum for 24 hours to make sure the pressure holds. We replace any hardware or parts as is necessary and clean all incubators thoroughly prior to shipment.

The photos above are representative. Please bear in mind that the equipment shown is currently in storage in our warehouse and that in addition to testing each machine we will clean all the equipment thoroughly prior to shipment. We often have multiple units of each model in stock and sometimes we're unable to feature photos of every single unit. At your request, we can provide photos of the equipment in your order after it has been tested and cleaned.
