A comprehensive range of replacement valve parts for selected Thermo Fisher Scientific HPLC systems.

• Vespel is a polyimide with low wear and high chemical resistance recommended for use with solutions under pH 10
• More basic solutions dissolve Vespel over time and damage the rotor seal
• Tefzel is recommended for use in applications such as higher concentrations of methylene chloride or dimethyl sulfoxide (DMSO)

Agilent valve supplies work seamlessly with selected Thermo Fisher Scientific HPLC systems for reliable, accurate, and reproducible results. Stators are available in 316 stainless steel, PEEK, and ceramic depending on the specifications of the original equipment manufacturer.
