MarvelXACT PEEKsil is comprised of a fused silica capillary encased in 1/32" OD PEEK tubing, ideal for extremely low volume and bioinert applications. The flexible tubing is easily routed through the LC system and can be connected and disconnected multiple times. The 1/16" tubing ends and integrated fittings are compatible with any 10-32 coned port, and are finger-tight — no tool required for UHPLC connections up to 19,000 psi. The fitting produces a haptic "click" feedback when it reaches the optimum torque to eliminate the risk of under- or over-tightening. The PEEK tubing end seals at the port bottom which eliminates dead volume and minimizes carryover risk, peak tailing, and peak broadening. Tubing volume: 0.074uL.
