GT Stirrer Seal with PTFE Guide Sleeve – Borosilicate Glass 3.3

The GT stirrer seal made of borosilicate glass 3.3 enables safe and leak-tight operation of stirring devices in laboratory flasks and reaction vessels. The integrated PTFE guide sleeve ensures high chemical resistance against a wide range of organic solvents, acids and bases, while providing precise, low-play guidance of the stirrer shaft. The seal is suitable for use in organic synthesis, pharmaceutical research and general laboratory practice. Thanks to the standardised joint sizes NS 29/32 and NS 45/40, the GT stirrer seal is compatible with common round-bottom flasks and reaction vessels. It is available in various versions for shaft diameters from 6 to 16 mm, covering a wide range of laboratory applications.
