Our Dupont FEP Tubing Sleeve is carefully manufactured using FEP fluoropolymer -€“ a highly inert, melt-processed polymer that serves as an excellent alternative to PTFE. It is prepared using our in-house extruded tubing, our sleeves provide better concentricity and easy insertion of capillary tubing. Additionally, by using a sleeve instead of a modified ferrule, dead volume in the receiving port is minimized, ensuring better results. It is designed for use with the A-350 cutter. These replacement sleeves also come in a 10 pack. Brochure
