Tube adapters have male 1/4-28 threads going to 1/4" or 1/8" OD tubing.

Luer adapters make a leak-tight connection from male or female luer to 1/4-28 threads or 1/16" Valco fitting detail.

Our luer adapter bulkhead union connects a male or female luer to 1/4-28 or 1/16" (10-32) zdv fittings. These are the ideal fittings for through-the-panel syringe injections. The 1/4-28 versions include flangeless 1/4-28 fittings for 1/16" tubing. Versions with 10-32 connections (for 1/16" tubing) include a finger-tight PEEK nut and a ferrule of the same material as the union.

Versions adapt male or female 1/2-28 fittings to male or female NPT.

This adapter permits Valco 10-32 fittings to be installed into any 1/4-28 fitting detail.

Material: PEEK.

Sold individually.

Choose from a variety of coupler IDs, indicated by the color of the sleeve (which coordinates with the color-coding of our PEEK tubing).

A unique feature of this column coupler is that it adapts automatically to fit all pilot lengths – Valco, Waters, Upchurch, Rheodyne, etc. Since the tubing bottoms out in any fitting detail, added void volume is minimal. Material is PEEK.

The Cheminert Perifit™ is a unique fitting with a barb on one end and a 1/4-28 female fitting on the other, for connecting a FIA line with the most commonly used peristaltic tubing. The fitting is compact and easy to install while providing a secure, trouble-free connection. A Perifit can be used as a "stop" on standard inexpensive Tygon® tubing, eliminating the need to buy the more expensive pre-cut tubing with pre-installed stops.

Unlike many competitive systems, Perifits are reusable as the tubing wears. Three sizes of Perifits are available to cover the range of tubing most commonly used in FIA.

These convenient-to-use filters can be simply dropped into any 1/4-28 fitting detail, such as in a union. The filters are constructed of PTFE and CTFE, with a Type 316 stainless low-pressure-drop screen.

This all-PEEK filter can be placed in any 1/16" line, providing filtration to 0.5 microns. The filter can be changed without tools, since both the filter housing and the fittings are designed to be hand tightened.

The filter element is PEEK-encapsulated titanium.
