PEEK Needles

Needles made from HPLC grade polyetheretherketone (PEEK) for applications and liquids that are sensitive to stainless steel contact. Choose from large removable needle or Kel-F  termination hub. Both styles feature a blunt point style .

Hamilton PEEK Needles

Metal-free, worry-free performance

Hamilton’s PEEK needles are a high-performing alternative to stainless steel in sensitive applications.  Polyetheretherketone (PEEK) is the same material used in HPLC tubing and fittings and is prized for its resistance to pressure and chemicals. This means that your PEEK needle provides consistent and reliable performance over time. Select a PEEK needle with a large removable needle (RN) or Kel-F  connection type; each features a blunt point style and 50.8 mm (2 inch) needle length and is offered six to a pack.

Needle Length Guide

Needle length is a critical consideration for every application. Each needle hub design requires a slightly different length definition. It doesn't matter if the application is utilizing lab needles for life science injection or environmental analysis of ground water, the injection needs to hit the right target. This guide illustrates how to make the different measurements.
