Trutherm Lab Box Furnace models are designed for laboratory users needing a box chamber, digital controls, temperature choices and chamber dimension options.
Trutherm manufactures 600 Degree Celsius (°C) Lab Box Furnace 300 x 300 x 450 MM Chamber for buyers who search by exact machine type, chamber size and 600°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 300 x 300 x 450 MM chamber with usable chamber volume of 40.5 litre, approximate power load of 12.9 kW, square 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.

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.
Heat-treatment cycles such as annealing and tempering depend on a stable soak temperature, and the muffle-lined box chamber isolates the workpiece from direct flame or element contact for even heating.
Compared to a tube or ashing furnace, this box (chamber) furnace gives the largest usable loading footprint for its outer size, so it suits irregularly shaped parts, trays and multiple crucibles better than a cylindrical or vent-style chamber.
