Thermo VO 19.8 220C 120 - Vacuum Oven, 19.8L, 120 VAC, 220 Deg C max, 600 watt, with analog dial bimetellic thermometer display.

Vacuum Oven

• Applications in a reduced atmosphere
• Maximum temperature: 220°C / 428°F
• Basic controls with choice of hydraulic bimetallic thermostat and LED
• Provide an entry level option for everyday drying and heating

Achieve maximum temperatures of 220°C (428°F) with Thermo Scientific™ Vacuum Ovens, while benefiting from two control configurations and display options. These ovens feature independent vacuum and purge needle valves. Radiant warm-wall heating system optimizes uniformity and conserves chamber space for drying, curing, vacuum embedding and plating applications.

Drying processes are essential to various workflows in the laboratory and many times, vacuum drying is needed for delicate samples at low temperatures. Offered with various temperature ranges and sizes, Thermo Scientific vacuum ovens are designed with safety, reliability and efficiency in mind-and offer features that tailor to your specific applications.

Typically used within the pharmaceutical, food, electronics, medical devices and aerospace industries-the Thermo Scientific vacuum ovens portfolio offers a variety of models to accommodate applications such as:

• Moisture removal from food such as dairy products
• Moisture removal from sensitive products such as electronics
• Complex vacuum drying processes, with specific goals such as: > Prevention of oxidation  > Removal of moisture residue by addressing capillary effects.
• Defined heating protocols with temperature ramping under vacuum
• Storage of oxygen sensitive material in the presence of inert gas, e.g. nitrogen
• Tempering
• Solvent, epoxy and essential oil removal

Why dry in a vacuum?

Using a vacuum for drying requires a lower temperature than standard drying ovens. Under a vacuum, humidity evaporates below the usual boiling point of the liquid that needs to be removed - resulting in a more gentle drying process for delicate samples. The graph to the left illustrates that water will evaporate at a much lower temperature than 100°C, with lower pressure.
