Muffle Furnace
Product Code : JA-LE-3997
The Muffle Furnace (SKU JA-LE-3997) is a benchtop laboratory muffle furnace with a 200 x 200 x 200 mm chamber, rated for continuous work at 1100 °C and for short periods at up to 1200 °C. Alumina fibre ceramic insulation surrounds the chamber, resistance-wire coils heat it from three sides, and a separable 30-segment programmable PID controller with a K-type thermocouple sets the temperature. It is supplied by JaincoLab for college, research and quality-control laboratories.

Applications of the 1100 °C muffle furnace
Programmable heating to 1100 °C in a closed chamber suits work such as:
- Ashing and loss-on-ignition tests on food, soil, feed and pharmaceutical samples held in crucibles
- Heat treatment, annealing and hardening trials on small metal specimens
- Firing and sintering small ceramic and glass samples with multi-step programmes
- Gravimetric analysis steps that need a steady high temperature
Scope of supply and ordering
The furnace is listed with its K-type thermocouple and separate temperature control unit; crucibles, tongs, packing and delivery time are itemised on the quotation.
Frequently asked questions
What temperature can this muffle furnace run at?
It works continuously at 1100 °C and can reach 1200 °C for short periods, with a stated accuracy of ± 1 °C.
How large is the chamber?
The chamber measures 200 x 200 x 200 mm, which is also the listed maximum sample size.
Can the heating cycle be programmed?
Yes. The PID controller holds up to 30 segments, so ramp and hold steps run automatically, and the control unit can be separated from the furnace.
Can the sample be watched during heating?
Yes. A 0.5 inch quartz glass window gives a view into the chamber while it is hot.
