Product Details

CE_Standard 1400℃ Muffle Furnace
BR-14S muffle furnace consists of high quality alumina fiber brick and SiC heating elements with special design. This lab furnace can be used up to 1400℃. It is an ideal electric furnace for materials annealing and sintering in your research laboratory.

Features
1. Operation Temperature: 1300℃ (1400℃ for short time).
2. Maximum energy efficiency is achieved by surrounding the chamber with thermal-efficient alumina fiber ceramic insulation.
3. Heavy duty double layer structure with cooling fan. Lower temperature in outside case.
4. PID automatic control via current limiting phase angle fired the resistor, e.g. SCR (Silicon Controlled Rectifier).
5. Power control with 51 segments programmable.

. Application Notes

Using Attentions

●  Cooling rate shall also not exceed 10℃ /min.  
●  Toxic or explosive gases are not recommended for use with this furnace without necessary safety controls and supervision.  
●  Small cracks may appear on the surface of the refractory ceramics over extended use. This is a normal occurrence and the cracks may be repaired with alumina coating.
●  Refractory door block must be inserted before closing door.
