Is there an easy way to do fluidic connections with correct torque?

More force does not result in better fluidic connections. In fact, using too much tightening torque, may damage your tubing, fitting, or the receiving port, resulting in leakage, additional maintenance, or a distorted flow path that can impact the output precision of your fluidic instrument. This can be especially delicate when connecting HPLC and UHPLC separation columns, or in other similar situations where a flow path component often is exchanged by different users.

In the video interview below, Dr. Fritiof Pontén, CEO of Biotech Fluidics, summaries how to assemble reliable fluidic connections, avoiding leakage and distorted tubing. This was recorded by LCGC International at the exhibition Analytica 2024 in Munich, Germany.

Dr. Pontén explains how leak free connections are assembled by using an accurately cut tubing, the right type of fitting, and the correct tightening torque. He furthermore highlights the MarvelXACT™ and Intuitive™ fitting systems that has built-in torque limiting functions that makes it impossible to overtighten them. For other type of fittings, Dr. Pontén recommends using a torque wrench to make sure you apply the right force during assembly of the fluidic path.
