Nitrogen/Argon /other inert gases atmosphere controlled muffle furnace introduction
KJ1200A series atmosphere controlled muffle furnace is designed for material synthesis under controlled inert gas atmoshphere up to 1200 ºC. The furnace consists of high quality alumina fiber brick and NiCrAl heating elements with heated chamber of 80L capacity, as well as vacuum sealed steel case with water cooling jacket It is an ideal tool for preparing new materials which requires a heat treatment under inert gas.
Main technical features of the atmosphere furnace | |
