MarvelX™ UHPLC fittings & assemblies

Finger-tight zero dead volume UHPLC connections up 1300 bar (19000 psi) routinely. The lack of any ferrules guarantees perfect fit of the tubing end to the sealing surface of the port, thus eliminating peak efficiency loss. Recommended to be combined with pre-cut flexible stainless-steel tubing.

MarvelXACT™ in action

The expertly designed MarvelXACT™ connection system takes the guesswork out of your process by eliminating the risk of under- and over-tightening, with a patented torque-limiting mechanism. This unique feature provides a haptic “click” feedback when it reaches the optimum torque, assuring a perfect connection every time. Built with sturdy, bioinert PEEK and stainless steel, MarvelXACT™ can be connected and disconnected more than 100 times. The MarvelXACT™ connection system incorporates flexible 1/32” OD tubing with 1/16” OD ends to easily route through your system, is compatible with 10-32 coned receiving ports, and is absolutely finger-tight – no tool required.

MarvelXACT™ also incorporates the advanced IDEX MarvelX™ sealing technology to deliver precise face sealing (sealing at the port bottom), which eliminates additional internal volume, and minimizes carryover risk, peak tailing, and peak broadening. Additionally, MarvelXACT™ utilizes the exclusive next-generation IDEX patented technology to auto-adjust to various port depths thereby ensuring zero dead volume seal with every HPLC and UHPLC instrument from all manufacturers.
