1200C high temperature box type electric laboratory furnace
A. ST-1200RX Box type Muffle Furnace feature
a). ST-1200RX box type muffle furnace, heating element embedded in the chamber wall. When Muffle furnace heating, can ensure uniform temperature in the furnace.
b). Muffle furnace chamber of the use of advanced lightweight aluminum oxide material molding, traditional muffle furnace compared the weight, reduce 40%. Heat preservation effect is good, temperature increase speed increased a times, save energy. Furnace service life by four times.
c). Use double deck ventilation cooling structure, muffle furnace work in high temperature, and the furnace shell surface keep low temperature, avoid scald the operating personnel, safety is greatly increased.
