Capillary, Fittings & Connectors for HPLC

Agilent InfinityLab Quick Connect and Quick Turn fittings are truly high-pressure, finger-tight fittings for connections onto columns or other instrument positions for your HPLC & UHPLC. These HPLC column connectors have innovative spring-loaded design to ensure zero-dead-volume connection, helping you avoid the broadening or tailing of peaks, loss of resolution, and overall poor chromatographic performance associated with poorly connected fittings.

InfinityLab Quick Connect UHPLC fitting is finger tight up to 1300 bar, for UHPLC column connections as easy as pressing a lever.

How It Works

A unique, spring-loaded design

Agilent InfinityLab Quick Connect fittings and Quick Turn fittings use a unique, spring-loaded design. The spring of these finger-tight fittings constantly pushes the capillary towards the receiving port. The spring-loaded mechanism ensures a zero-dead-volume column connection for UHPLC and HPLC systems to avoid poor chromatography, such as peak broadening or tailing, split peaks, and carry over. The fittings are reusable and can ensure perfect connectionsfor up to 200 uses. 

Perfect connection in three simple steps

Poorly connected fittings are one of the top reasons for broad or tailing peaks, loss of resolution, and overall poor chromatography. Perfect connections can be created quickly and easily, without any tools, using our finger-tight fitting for UHPLC and HPLC analysis. Ideal for column connections that you connect and disconnect most often, there are just three simple steps:

  • Connect the fitting with the column
  • Hand-tighten the blue nut until feeling the first resistance
  • Depress the lever to perform 1300-bar tight column connection 

Fitting and capillary work together seamlessly

It is important to use Quick Connect and Quick Turn fittings with the proprietary capillaries specifically designed for them. The Quick Connect fitting requires a capillary with a spring and a PEEK component. The Quick Turn fitting needs a capillary with a long socket due to its internal spring action. Depending on your application needs, you can select from Quick Connect/Quick Turn capillaries made from stainless steel, PEEK-lined stainless steel, and MP35N.
