Product Overview
PT D219/1800/8/3 is a 800C Vertical Three zones Tube Furnace with OD219mm Tube. The furnace is designed with three heating zones. Temperature zones are insulated well, which can effectively reduce the temperature difference. The furnace chamber is made of vacuum filtered ceramic fiber material. Embedded HRE heating wire heated, max working temperature up to 800 degree C. The heating chamber can fit processing tubes such as quartz or stainless steel well.The top of the furnace body is designed with a furnace tube fixing device. This tube furnace is especially suitable for the decomposition of sulfuric acid and hydrogen production experiments at high temperature.

Application Notes
- Quartz tube pressure should be lower 0.02MPa
- Gas source should equip the pressure reducing valve
- Before filling reduction gases like H2, should pump the air out of the tube
- When filling gases from gas inlet in the tube, should make sure the gas outlet valve open
