Standard Probe Liners are constructed from 5/8″ diameter tubing and have #28mm ball joint attached.  Liners are available in a variety of materials including borosilicate glass, quartz, stainless steel, Alloy 600 , Hastelloy Alloy and PTFE/FEP glass-filled; liners with integrated nozzles require a ball joint adapter.  We also offer glass and quartz liners with male 14/35″ taper joint for attaching to the appropriate nozzle, eliminating the need for the 5/8″ union.
