Muffle Furnace
Muffle Furnace (Product Code: SLE/MCE/21) is a high-temperature laboratory furnace used to heat-treat, anneal and ash samples in materials testing, metallurgy and chemistry laboratories. It is available in 1100°C and 1400°C versions with a programmable PID temperature controller, SCR power control, silicon carbide heating rods and 42 or 56 litre chambers. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM laboratory equipment manufacturer, at its own factory in Ambala, India.

What Is the Muffle Furnace Used For?
In a materials testing lab the furnace hardens, tempers, normalises and anneals steel specimens, so students can measure how hardness and toughness change with heat treatment. Chemistry, soil and food laboratories use the same furnace to ash samples in crucibles and to dry or ignite residues at controlled temperatures. The programmable controller lets staff set a heating profile and leave it to run, while the uniform heating rate helps specimens in different parts of the chamber receive similar treatment.
Load and unload with long crucible tongs and heat-resistant gloves, avoid opening the door at full temperature, and never place wet or volatile material straight into a hot chamber. Choose the 1400°C version only if your work needs it, as the 1100°C unit covers most heat treatment and ashing. For institutions comparing a laboratory equipment manufacturer in India, buying a furnace from the maker simplifies later support.

Frequently Asked Questions
What temperatures does the Muffle Furnace reach?
The Muffle Furnace is available in 1100°C and 1400°C versions. Their continuous operating temperatures are 1000°C and 1300°C respectively, so choose the version whose continuous rating covers the temperature your process holds for long periods.
What chamber sizes are available for the Muffle Furnace?
The Muffle Furnace is offered with a 300 x 300 x 457 mm chamber of 42 litres or a 300 x 300 x 609 mm chamber of 56 litres. The larger chamber suits batches of specimens or several crucibles at once.
How is temperature controlled in the Muffle Furnace?
The Muffle Furnace uses a programmable PID temperature controller with SCR power control and a K type or R type thermocouple. This gives a uniform heating rate and steady holding temperature for heat treatment and ashing work.
What is the Muffle Furnace built from?
The Muffle Furnace has silicon carbide heating rods, a chamber of ceramic fibre board and ceramic zirconium board, ceramic fibre blanket insulation and a powder-coated mild steel exterior. It is fitted with safety devices and built for long runs.
Who manufactures the Muffle Furnace?
The Muffle Furnace is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), the OEM, at its own licensed factory in Saha, Ambala, Haryana, India. Buyers get quotations and spares support directly from the manufacturer.
What power supply does the Muffle Furnace need?
The Muffle Furnace is listed for 220 V, 50 Hz or 3 phase 440 V, 50 Hz supply. Tell us which supply your laboratory has, together with the temperature and chamber size you need, so the quotation matches your site.
Is a calibration certificate available for the Muffle Furnace?
Calibration-certificate availability for the Muffle Furnace controller and thermocouple should be discussed with us before you order. Raise it on your enquiry through the contact page so the quotation can address it.
