1200. C High Temperature Vacuum Atmosphere Muffle Furnace with 200X200X300mm Chamber

1200. C High Temperature Vacuum Atmosphere Muffle Furnace with 200X200X300mm Chamber. High temperature and corrosion resistant chamber, anti-oxidation & crack-proof, long-life heating elements for repeated heating and cooling cycles. Thickened sealed furnace door with good air tightness, locking internal heat to reduce temperature fluctuation and ensure stable test data. User-friendly digital operation panel with built-in common sintering programs, easy to operate even for novice lab staff. Suitable for material sintering, ceramic firing, sample ashing, metal heat treatment, chemical calcination and other high-temperature experiments. Adjustable heating rate from 1.C/min to 10.C/min, slow heating prevents cracking of fragile experimental samples. Wide temperature range of 1200-1800.C, customizable cavity sizes for different experimental samples.
