Temperature range: Ambient +10°C to 220°C
0.8 Cu ft capacity
90-day warranty
VWR Collection Vacuum Ovens are designed for drying media under carefully controlled conditions - in a normal atmosphere, a vacuum of up to 30 inches Hg, or an inert gas atmosphere. The oven is primarily used for desiccating, vacuum embedding, plating and electronic component processing. Non-corrosive, nonflammable gases such as nitrogen and carbon dioxide can be used in the oven.
Uniform radiant wall heat, with no internally exposed heaters, optimizes chamber space. 3” (76mm) of glass wool insulation throughout helps maintain temperature uniformity effectiveness. Temperature is controlled by a hydraulic thermostat and can be read on the dial thermometer.
All controls and connections (except electrical power) are located on the front vertical panel - these include lighted power switch, vacuum gauge, temperature control, vacuum control valve and nickel-plated hose connectors. The silicone door gasket assures a tight seal at all vacuum levels. A high strength tempered glass window allows full view of oven contents. The shelf assembly removes for easy cleaning.
The chamber of the unit is not designed for exposure to concentrated solvents, oils, concentrated acids or dilute sodium hydroxide.
This oven is used and reconditioned. Our technicians test ovens using a digital chart recorder to verify the accuracy of temperature controls and readouts. We replace any hardware or parts as is necessary and clean all incubators thoroughly prior to shipment. We typically leave vacuum ovens under vacuum for 24 hours to ensure chamber integrity.
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.
