A vacuum tube furnace is a type of furnace that can heat materials, typically metals, to very high temperatures and carry out processes such as brazing, sintering and heat treatment with high consistency and low contamination. The tube furnace was invented in the first decade of the 20th century and was originally used to manufacture ceramic filaments for Nernst lamps and glowers.
Lab furnaces provide continuous heating to process samples and materials. They are generally built from high temperature (refractory) materials so that they can maintain high temperatures without breaking down.
A muffle furnace is (usually) a front-loading box-type oven or kiln for high-temperature applications such as fusing glass, creating enamel coatings, ceramics and soldering and brazing articles. They are also used in many research facilities, for example by chemists in order to determine what proportion of a sample is non-combustible and non-volatile (i.e., ash).
Digital controllers allow RS232 interface and permit the operator to program up to 40 segments, such as ramping, soaking, sintering, and more. Also, advances in materials for heating elements, such as molybdenum disilicide offered in our 1600°C and 1700°C furnaces, can now produce working temperatures up to 1750 degrees Celsius, which facilitate more sophisticated metallurgical applications.
