Tube Vacuum Furnace


Introduction :

Vacuum quartz tube vacuum laboratory furnace (25—50 diameter) designed for heating small samples up to 1100oC. Stainless steel vacuum flanges with valves, vacuum pressure gauge and quartz tube are included for immediate use. Built-in precision temperature controller can program up to 30 segments of heating, dwelling and cooling steps. The furnace can be set up in both vertical and horizontal positions to meet various applications such as sample heating, VLS, CVD and quenching tests. Set the furnace horizontally or at an angle to grow electronic crystals for semiconductor industry use or rotate it vertically for sintering applications.

Application :

Vacuum  tube laboratory furnace used to produce a large number of nano carbon materials, such as, Carbon nanotube powder, carbon nano tube film and directional carbon nano tubes, etc. It can also be used vacuum sintering, atmosphere protective sintering, nano material production,
