Chromatography Fittings
MilliporeSigma™ Supelco™ MicroTight Adapters PEEK
These adapters will help create a true zero dead volume (ZDV) connection between 1/16 in. I.D. tubing and capillary tubing. MicroTight Adapters allow connection of 1/16 in. O.D. tubing directly to 1/32 in. O.D. and 360 μm tubing.

MilliporeSigma™ Supelco™ Swagelok™ Union Cross, 400-4, Brass, 1/4 in.
Union cross generally divides the eluent flow into three directions which is coming from the pump. In gas system, pure gases from mass flow controllers are converged at the union cross and in turn flow into different size tubing to generate turbulence which produce homogenized gas.
