vacuum vertical tube furnace is a 1500℃ Max. high temperature and high vacuum vertical tube furnace. The crucible that hangs inside tube can be rotated under vacuum for uniform sintering, and crucible can be lift manually to make sample change at easy. Water cooling flanges and recirculating water chiller are included for immediate use.

vacuum vertical tube furnace

vacuum vertical tube furnace fields application:

It is mainly used for laboratory calcination and drying of battery positive and negative electrode materials, non-strong acid and alkaline powder materials, and granular materials. Users can choose to fire under vacuum or atmosphere protection according to the materials to be fired.
