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 880 x 525 x 525 MM chamber with usable chamber volume of 242.6 litre, approximate power load of 26.6 kW, rectangular - wide 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 annealing, tempering, hardening and general heat-treatment of metal and ceramic parts in tool rooms, forge shops and QC labs.

Equivalent chamber references: 880 x 525 x 525 MM, 88 x 53 x 53 CM and 35 x 21 x 21 INCH. Buyers searching for 900°C Lab Box Furnace 880 x 525 x 525 MM; Lab Box Furnace 900°C 880 x 525 x 525 MM; Lab Box Furnace 880 x 525 x 525 MM 900°C; 880 x 525 x 525 MM 900°C Lab Box Furnace; 900 Degree Lab Box Furnace 880 x 525 x 525 MM; Lab Box Furnace 900 Degree 880 x 525 x 525 MM can verify the same physical chamber on this canonical product page before requesting price, GST invoice, packaging and delivery.

Where sample orientation is not critical, the flat shelf and square chamber of a box furnace generally load faster than a cylindrical tube furnace of similar volume.

Box furnaces take their name from the simple rectangular chamber, which makes them easy to load with trays, crucibles or irregularly shaped parts through a front-opening door.
