Furnaces built around your process

Shrinitha Scientific has been manufacturing laboratory furnaces in India for over 18 years. Every unit is assembled at our Vasai works, from the ceramic fibre insulation and heating elements through to the control panel and safety interlocks.

A laboratory furnace is chosen by what happens inside it — the sample size, the maximum temperature, the ramp and soak profile, and whether the process needs air, an inert gas or vacuum. Tell us those four things and we will recommend the right model, or build one to suit.

The range below covers ashing and sintering in a muffle chamber, gas-flow work in a tube, thin film deposition in a CVD system, and oxidation-free heating in vacuum and atmosphere furnaces.

  • 1100°C to 1800°CKanthal, SiC or MoSi₂ elements selected for the working temperature.
  • PID and programmable controlSingle set point, multi-step ramp and soak, or touchscreen with data logging.
  • Safety as standardOver-temperature cut-off, door interlock and earthed, ventilated enclosure.
  • Custom chamber sizesChamber, hearth plate and tube diameter made to the sample you run.

Frequently Asked Questions (FAQs)

What is the difference between a muffle furnace and a tube furnace?

A muffle furnace heats a rectangular chamber and suits ashing, sintering and general high temperature work where the sample sits on a hearth plate. A tube furnace heats a cylindrical work tube instead, which lets you pass a gas through the hot zone or pull a vacuum around the sample. If your process needs a controlled atmosphere, start with the tube furnace.

Can the chamber size and temperature range be changed?

Yes. Chamber dimensions, tube diameter, heating elements, insulation thickness and the control panel are all built to requirement. Send us your sample size, working temperature and the cycle you run, and we will put together a specification and quotation.

Which controller should we choose?

For a single holding temperature, a PID controller with digital set point is enough. If your method has a ramp, a soak and a controlled cool, choose the programmable controller. Labs that need traceable records for audits should take the touchscreen version with data logging.

What warranty and service do you provide?

Every furnace ships with a standard warranty, installation support and a spares list. We supply heating elements, thermocouples, controllers and insulation directly, and offer annual maintenance contracts for labs that need scheduled servicing and calibration.

Do you supply outside India?

Yes. Our furnaces are in use in more than ten countries. Export packing, documentation and voltage or frequency changes are handled before dispatch.
