Glovebox-Compatible Split-Type Vertical Furnace - VBF1200XVGB

The VBF-1200X-VGB is a vertical well furnace designed for connection to a glovebox. It has a maximum heating temperature of 1100℃ and uses a quartz tube as the sealed chamber. The quartz tube size is φ200*340 mm. It is suitable for heat treatment of materials sensitive to moisture and oxygen. After heat treatment, samples can be removed directly from the well furnace and transferred into the glovebox for further processing.
