KSL1200X 1200°C Muffle Furnace with 12″x8″x5″ Chamber, Quartz Observation Window, Vent Port, and Programmable Controller
The KSL1200X is designed for laboratory applications requiring precise high-temperature sample preparation up to 1200°C. Its 7.2-liter heating chamber with dimensions of 12″ x 8″ x 5″ accommodates a variety of sample sizes, making it suitable for research and dental laboratories where controlled thermal processing is essential. This furnace facilitates energy-efficient heating with a durable design that ensures operator safety during extended use.
At the core of the KSL1200X is a fibrous heating module surrounded by high-purity alumina fiber insulation, which maximizes thermal efficiency and minimizes heat loss. The furnace features a heavy-duty double-layer structure equipped with a cooling fan to maintain safe exterior temperatures. A quartz glass observation window (0.5″ diameter) allows visual monitoring of samples without opening the door, while a vent port on top serves as a gas outlet or can be fitted with a stainless steel gas fill tube included for controlled atmosphere experiments or feedthrough applications such as temperature calibration or electrical measurements.
