KSL1200XJH 1200°C Hybrid Muffle Furnace with 6″x6″x7″ Chamber and Optional Quartz Tubes (2″/3.1″/4″ OD) for Vacuum and Controlled Atmosphere Processing

The KSL1200XJH is designed to meet versatile laboratory material processing needs by combining a box-style muffle furnace with an optional tube furnace capability. Its 6″x6″x7″ heating chamber accommodates bulk samples for high-temperature treatments up to 1200°C in air or inert atmospheres. For applications requiring controlled atmospheres or vacuum conditions, quartz tubes of various diameters (2″, 3.1″, or 4″ outer diameter) with flanges can be inserted from the top, converting the unit into a tube furnace capable of vacuum levels down to 10^-6 torr with appropriate pumping systems.

Heating is achieved via high purity alumina fiber insulation surrounding the chamber, ensuring energy efficiency and uniform temperature distribution. The furnace features a heavy-duty double-layer steel casing with forced-air cooling and an integrated cooling fan to maintain safe exterior temperatures. Temperature control is managed by a digital PID controller with auto-tuning, programmable ramping and dwelling steps, and ±1°C accuracy, supporting precise thermal profiles for complex processes.
