Tube Furnace Manufacturer & Supplier in Kolkata
Kolkata, West Bengal
Shrinitha Scientific is a tube furnace manufacturer supplying laboratories and industries across Kolkata. Every furnace is built at our own manufacturing unit in Vasai East, Maharashtra, tested before dispatch, and delivered to Kolkata with installation guidance and spares support.
Kolkata has a long tradition of materials research at CSIR-CGCRI, IACS and Jadavpur University, a large foundry and engineering belt in Howrah, the Haldia petrochemical complex, and busy gold jewellery and assaying markets. Many of them need a reliable tube furnace for controlled-atmosphere annealing, calcination, sintering, CVD and material synthesis. We supply 1200°C and 1800°C tube furnaces in single- or multi-zone designs, horizontal or vertical, with quartz or alumina work tubes and optional gas-flow and vacuum accessories.
What is a Tube Furnace?
A tube furnace is an electrically heated cylindrical furnace in which samples are processed inside a quartz or alumina work tube. Because the tube can be sealed, purged with gas or evacuated, it is the standard choice for controlled-atmosphere annealing, calcination, CVD and material synthesis.
Tube Furnace Models Supplied in Kolkata
Single- or multi-zone with quartz or alumina tube. Ideal for annealing, calcination, CVD and catalyst work under gas.
MoSi2 heating elements with high-purity alumina tube for advanced ceramics and high-temperature materials research.
Prices shown are starting prices for the base configuration, ex-works Vasai, excluding GST. Final price depends on tube size, zones, controller and options. Each furnace is made to order and dispatched in 7–21 working days; delivery to Kolkata takes 5–8 days and is included in the quote. As furnaces are custom-built, returns are not accepted; manufacturing defects are covered under our service support.

Tube Furnace in Kolkata – FAQs
1. Do you supply tube furnaces in Kolkata?
Yes. Shrinitha Scientific manufactures tube furnaces at its own works in Vasai East, Palghar, and supplies them across Kolkata and its industrial areas, including Jadavpur, Salt Lake & New Town, Howrah and Dankuni & Uluberia.
2. What temperature ranges are available in your tube furnaces?
Tube furnaces are offered in models up to 1200°C and 1800°C, in single-zone or multi-zone designs. Quartz work tubes are used at lower temperatures and high-purity alumina tubes for higher-temperature operation.
3. Can I inspect the tube furnace before it is dispatched to Kolkata?
Yes. You are welcome to visit our works at Vasai East, Palghar, and see your furnace tested before it is packed and dispatched by road to Kolkata.
4. Which tube furnace is suitable for sintering of advanced ceramics?
An 1800°C tube furnace with a high-purity alumina tube is used for sintering advanced ceramics under air or controlled gas. Programmable ramps protect samples during binder burn-out.
5. Can you make a tube furnace with a custom tube size or gas and vacuum setup?
Yes. Heating-zone length, number of zones, work tube diameter and material, orientation, controller and gas-flow or vacuum accessories can be configured for your application.
