- Large grinding opening of the spindle valve allows a fast inflow of gases or air
- Tight closure due to standard ground joint
- For lid outlets of NOVUS type desiccator (standard ground joint NS 24/29)
The PTFE spindle valve is used for airtight sealing of a desiccator. For this purpose, the spindle tap is connected to the standard ground joint of the desiccator cover. The very small, punctual opening in the lower part of the spindle valve allows a slow inflow of gases or air when the valve is opened, thus reducing a strong turbulence inside the desiccator. The PTFE spindle valve is used for airtight sealing of a desiccator.
