The IDEX 200 µL PEEK Sample Loop for 9725/9725i Valves (9055-025; Cole-Parmer item 02016-80) is a flexible, metal-free sample loop designed for compatible chromatography injection valves. It provides a nominal 200 µL sample volume with 1/16 in OD x 0.51 mm (0.020 in) ID PEEK tubing and is supplied with two unswaged fittings.
Key Features
- Flexible PEEK construction, providing a metal-free alternative to stainless steel sample loops
- Biocompatible fluid path, supporting applications where metallic wetted materials are undesirable
- Broad solvent resistance, with PEEK described by IDEX as inert to almost all organic solvents
- 200 µL nominal sample volume, providing the verified capacity for this loop configuration
- Designed for 9725 and 9725i valves, matching the specified chromatography injection valve configuration
- Clean, straight-cut loop ends, supporting straightforward installation into compatible valve ports
- Two unswaged fittings supplied, allowing the fittings to reposition along the PEEK tubing during installation
