Needle seat, PEEK, 0.17 mm ID capillary, for 1290 Infinity II vial sampler G7129-87017
Agilent G7129-87017 is a PEEK needle seat assembly featuring a 0.17 mm ID capillary designed for Agilent 1260 and 1290 Infinity II/III Vialsamplers. It delivers leak-free fluidic coupling between the injection needle and analytical flow path, ensuring accurate sample delivery in HPLC systems.
Description
The Agilent G7129-87017 Needle Seat Assembly is an essential component of Agilent Infinity II and III LC Vialsampler autosampler modules (including G7129A, G7129B, and G7129C). It features a high-precision PEEK seat with an integrated 0.17 mm inner diameter capillary tube. Designed to withstand HPLC pressure and aggressive mobile phases, the PEEK material provides high chemical resistance and mechanical durability during repeated needle injections. The needle seat forms a high-pressure seal with the autosampler needle to prevent sample leaks and maintain low dead-volume fluidic connections. Regular replacement is recommended when experiencing leaks at the seat, increased sample carryover, baseline instability, or peak broadening caused by physical wear or capillary blockages.
