Couplings and connectors In high-pressure liquid chromatography (HPLC and UHPLC), the quality of the connection determines the analytical result. Inacom offers an extensive range of unions, tees, crosses and manifolds specifically designed for systems that require extreme pressure resistance and flawless fluid transfer.
Our connectors are optimised for standard 10-32 coned ports and suitable for 1/16” OD tubing. Thanks to a design with minimal or even zero internal dead volume (ZDV), these connectors help preserve the sharpness of your chromatographic peaks in every separation.
