DURAN® Stopcock with PTFE Spindle, for threaded outlets

  • Manufactured from borosilicate glass 3.3
  • Small grinding opening of the spindle valve allows a slow inflow of gases or air and thus prevents excessive turbulence
  • Tight closure due to standard ground joint
  • For threaded outlets of MOBILEX type desiccator (GL 32)
  • With PTFE spindle
Product Overview
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.
