Agilent G7129-87012 is an original needle seat assembly designed for Agilent 1290 Infinity II and 1290 Infinity III Vialsampler modules. The seat is made of PEEK and incorporates a capillary with a 0.12 mm inner diameter. It is intended for analytical LC applications with G7129A and G7129B modules.
Function in the Autosampler
The needle seat is an important part of the vialsampler injection flow path.
Its functions include:
- providing a tight seal with the needle during injection,
- directing sample into the flow path,
- minimizing leakage at the needle-seat interface,
- supporting reproducible sample introduction.
PEEK Material
The seat is manufactured from PEEK, commonly used in LC systems because of its:
- good chemical resistance,
- low adsorption,
- low metal interaction,
- suitability for analytical flow paths.
Compatibility
G7129-87012 is intended for:
- Agilent G7129A Vialsampler
- Agilent G7129B Vialsampler
- Agilent 1290 Infinity II LC System
- Agilent 1290 Infinity III LC System
It is compatible with the corresponding needle assembly for this platform, such as G7129-87201.
