High-Temperature Vacuum Tubular Furnace – 1200°C to 1450°C
Shrinitha Scientific is a manufacturer and exporter of Laboratory Vacuum Tubular Furnaces in India, specializing in high-temperature heating equipment for scientific research, material development, and industrial laboratory applications. Our Vacuum Tubular Furnaces are designed with temperature capabilities ranging from 1200°C to 1450°C to meet the requirements of advanced thermal processing under vacuum or selected controlled-atmosphere conditions.
A Laboratory Vacuum Tubular Furnace combines a precision heating system with a sealed tubular working chamber and a compatible vacuum arrangement. This configuration allows researchers to conduct thermal experiments under reduced pressure or selected gas environments, helping minimize unwanted atmospheric reactions and contamination when the process is properly configured.
Our furnaces are suitable for research laboratories, universities, material science departments, chemical laboratories, and industrial R&D facilities involved in high-temperature material processing, calcination, annealing, sintering, degassing, and material synthesis.
At Shrinitha Scientific, we provide application-specific furnace solutions with suitable heating elements, temperature controllers, vacuum connections, and work tube configurations to meet individual laboratory requirements.
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.
