MarvelXACT™ Connection Systems have been expertly designed to eliminate the risk of under or over-tightening with our patented torque limiting mechanism. This unique feature emits a haptic click feedback when it reaches the optimum torque. MarvelXACT incorporates our advanced 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.MarvelXACT incorporates flexible 1/32 OD tubing for easy routing through your instrument, and can be connected and disconnected more than 100 times. The connection system is compatible with 10-32 coned receiving ports and is absolutely finger-tight — no tool required.
