1200 ºC Split Tube Furnace with Vacuum Flanges & Quartz Tube 60--100mm

JZ-T1200 series furnace are split-able Tube furnace with Fe-Cr-Al alloy heating element. The furnace is installed with 60mm to 100mm O. D quartz tube with a pair of smart stainless steel vacuum sealing flange and valve / gauge which allow to heat sample under vacuum or flowing gas condition up to 1200ºC. Precision temperature controller can provide 30 segments heating and cooling steps with +/- 1 ºC accuracy.
