1200 ℃ Tube Furnace

1200 ℃ Tube Furnace
Product Details

BR-12NT tube furnace
BR-12NT horizontal tube furnace adopt a 40, 60, 70, 80 or 100mm O.D quartz tube and a pair of stainless steel vacuum sealing flanges with needle valves & gauge allow heating samples under vacuum or gas flow conditions. The temperature of this tube furnace is controlled by a high precision digital controller which provides 51 programmable segments with +/- 1℃ accuracy. The max. working temperature is 1200℃.
