Vacuum Oven

Vacuum oven, unlike general purpose oven, dries samples without oxidation and residue. Vacuum oven is an ideal choice; where, samples are dried in absence of atmosphere (vacuum condition) or presence of inert atmosphere (Argon, Nitrogen, Clean Dry Air). A vacuum oven has two ports; Vacuum Port with needle valve to connect vacuum pump and another is Inert Gas Port with needle valve to connect with gas cylinder. A microprocessor PID controller is fitted in vacuum oven to control the temperature inside the chamber. Analog vacuum gauge displays vacuum level. Temperature thermostat keeps the unit safe if temperature exceeds beyond set degree of vacuum oven.

The purpose of using vacuum oven is to eliminate surface reactions (condensation or oxidation) on the parts inside the oven. While determining the drying process, it is mandatory to define the chamber size, vacuum pump capacity and level of desired vacuum, and time to achieve this vacuum level.

Bionics Scientific is a leading vacuum oven manufacturing company in India. It has been highly acclaimed by experts from food, pharmaceutical and metal manufacturing units and other research organizations for its innovate range of vacuum ovens and customized solutions to meet specific research application. Our vacuum ovens are suitable for delicate drying processes, for example drying tiny parts or removing flammable solvents.

Our vacuum ovens accommodate nitrogen or inert gas purging / venting and supplied completely with vacuum pump and connection kits with over temperature protection device fitted. Temperature chart recorders and printers are optional. These vacuum ovens are often operated at temperature up to 200°C. The standard models of vacuum oven come with 45 liters to 520 liters of volume. Each vacuum oven delivers excellent heat transfer, fast heat up and safe operation.
