Vertical Tube Furnace

High Temperature Vertical Tube Furnace, 1200℃ 1400℃ 1600℃ Vertical Tube Furnace

BR-12NVT vertical tube furnace is a split vertical tube furnace with vacuum sealed 40mm, 60mm, 80mm and 100mm diameter quartz tube, which can achieve faster sample heating and quenching in vacuum or flowing gas. The precision temperature controller can provide 51 segments of heating and cooling steps with +/- 1℃ accuracy. It is an ideal furnace for making quenching tests and temperature measurements.

BR-14SVT vertical tube furnace is designed for quenching samples from high temperature into ice water or oil rapidly to study material phase transition.

BR-16MVT vertical tube furnace is using mosi2 as heating elements. It is designed for the heat treatment of all types of new materials under vacuum or other gases condition up to 1600℃.
