Box furnaces heat samples in an insulated chamber with direct access for loading and unloading. McQueen Labs offers Thermolyne™ muffle furnaces and Lindberg/Blue M™ box furnaces for applications including ashing, heat treatment, and material testing.

Choose by operating temperature, usable chamber dimensions, controller type, door configuration, and electrical requirements. Check whether your heating process needs a single ramp and dwell or a programmable sequence, and review the selected model’s safety features. For atmosphere-sensitive work, confirm its inlet and vent provisions. Browse Box Furnace Accessories for related components, or compare Tube Furnaces if your process requires a heated tube or controlled gas flow.
