Multi-Port HPLC Solvent Transfer Cap

The Multi-Port HPLC Solvent Transfer Cap is a specialized laboratory accessory designed to improve the safety, organization, and reliability of solvent transfer in High-Performance Liquid Chromatography (HPLC) and related analytical laboratory applications.

Manufactured by Micro Technologies, the cap provides an organized interface between mobile-phase solvent bottles and HPLC tubing. Its multi-port arrangement allows multiple solvent lines or related connections to pass through a single bottle cap while helping maintain a closed solvent-handling environment.

The system incorporates a unique anti-twist mechanism. The freely rotatable design allows the cap assembly to move without unnecessarily twisting connected tubing when the cap is opened, tightened, or handled. This feature is particularly useful in HPLC installations where multiple tubes are connected to a single mobile-phase bottle.

An integrated 0.1 µm air valve filter helps prevent external contamination of the solvent while permitting controlled air exchange as solvent is withdrawn from the bottle. This helps maintain cleaner mobile phases and provides additional protection against airborne particulate contamination.

The cap body is manufactured from polypropylene (PP), selected for its suitability in laboratory environments and compatibility with many commonly used laboratory solvents. The standard neck configuration is GL45, a widely used laboratory bottle thread size.

Different port configurations are available to accommodate laboratory requirements. Options include 1-port, 2-port, and 4-port configurations, enabling laboratories to select a suitable arrangement based on the number of solvent-transfer lines required.

The system is supplied with fittings suitable for different tubing outside diameters, providing flexibility when integrating the cap with HPLC solvent lines.

Anti-Twist Mechanism

One of the major features of the Multi-Port HPLC Solvent Transfer Cap is its anti-twist design.

The freely rotatable mechanism helps prevent connected tubes from twisting when the cap is opened or closed. This can simplify bottle replacement and routine solvent handling while reducing unnecessary mechanical stress on tubing and connections.

The mechanism is particularly useful when several solvent lines are connected through the same cap.

Air Valve Filter

The cap incorporates a 0.1 µm air valve filter designed to reduce contamination of the solvent from external particles.

As mobile phase is withdrawn from the bottle, filtered air can enter the container, helping maintain pressure balance while limiting particulate contamination.

Filter Rating

0.1 µm

This feature makes the cap suitable for laboratories where cleaner mobile-phase handling is important.

Tubing Connection Options

The cap can accommodate fittings for different tubing outside diameters.

The supplied fittings are designed for tubing sizes including approximately:

• Ø2 mm OD
• Ø1.6 mm OD
• Ø1 mm OD

This allows the system to be integrated with different HPLC solvent-transfer arrangements.
