Shaft guides, High Performance (HP), for standard taper ground glass joints
: COWIE
High Performance (HP) shaft guides provide an effective guide for use with glass and metal shaft stirrers over a wide range of temperatures without shedding particles from a specially formulated PTFE-PEEK seal whilst maintaining vacuum. The moulded-in PTFE-PEEK guide ring located at the end of the taper provides a guide to assist alignment of the shaft.
Shaft guides have an NPT thread for direct assembly into PTFE reactor lids or standard tapers for use with glass joints.
: PEEK has reduced chemical resistance compared to PTFE and may be affected by acids, phenols and halogen based compounds.
Maximum recommended speeds are 500 rpm continuous or 800 rpm intermittent.
