Suitable stirring shafts in PTFE
LAB-PTFE® HP Shaft Guides provide an effective guide for use with GLASS and METAL Shaft Stirrers over a wide range of temperature without shedding particles from a specially formulated PTFE-PEEK seal whilst maintaining vacuum.
In the version designated .PK a moulded-in PTFE-PEEK guide ring located at the end of the taper provides a guide to assist alignment of the shaft. For the PEEK version use the suffix .PK -eg, 005.0.0619.PK
Note: PEEK has reduced chemical resistance compared to PTFE and may be affected by acids, phenols and halogen based compounds.
The maximum recommended speeds are 500 rpm continuous or 800 rpm intermittent.
