About This 700°C Lab Muffle Furnace 850 x 885 x 850 MM Chamber

A laboratory-scale muffle furnace designed for research, testing, and small sample processing. Capable of reaching 1000°C, it provides a clean, isolated heating environment. The working principle features a ceramic muffle tube or box that surrounds the sample, heated by external elements. Its purpose is for applications like determining ash content (LOI), heat treating small metal samples, sintering experimental ceramics, or conducting ignition tests where contamination from the furnace walls or elements must be avoided. It is a standard piece of equipment in analytical and materials labs.

Equivalent chamber references: 850 x 885 x 850 MM, 85 x 89 x 85 CM and 34 x 35 x 34 INCH.

Trutherm manufactures 700 Degree Celsius (°C) Lab Muffle Furnace 850 x 885 x 850 MM Chamber for buyers who search by exact machine type, chamber size and 700°C temperature rating. This page is specific to the MM dimension version, so the chamber size is presented in the unit normally used in the buyer's drawing, tender or purchase request.

This configuration is suitable when the sample load must fit a 850 x 885 x 850 MM chamber with usable chamber volume of 639.4 litre, approximate power load of 39.5 kW, rectangular - tall chamber profile. It is commonly selected for laboratory, QC, metallurgical, ceramic, pharmaceutical and industrial heat-treatment work requiring stable heating and repeatable process conditions. Typical use includes general laboratory and industrial heat-treatment applications requiring stable, repeatable temperature control.

Routine QC and teaching labs value a muffle furnace precisely because one unit can cover several standard test methods without dedicated process-specific tooling.

Uniform chamber heating and a simple door-loading design make a muffle furnace straightforward to standardise across multiple operators and shifts.
