Laboratory Vacuum Tubular Furnace - Shrinitha Scientific

What Is a Laboratory Vacuum Tubular Furnace?

A Laboratory Vacuum Tubular Furnace is a high-temperature electric furnace designed to heat samples placed inside a tubular chamber under vacuum or a compatible controlled atmosphere.

The system generally consists of an insulated heating chamber, a work tube, vacuum-compatible sealing flanges, temperature control equipment, and a suitable vacuum pumping arrangement. The vacuum system removes gases from the working tube to establish the required pressure conditions before or during thermal processing, depending on the process design.

Compared with conventional heating equipment operating in ambient air, a properly configured vacuum tubular furnace can help reduce oxidation, limit atmospheric contamination, and support specialized thermal experiments.

Shrinitha Scientific manufactures Vacuum Tubular Furnaces with temperature capabilities from 1200°C to 1450°C, with configuration options selected according to the material, operating temperature, vacuum requirement, and intended application.
