Patent number: 10001463Abstract: Described is a dispensing needle for a fraction collector. The dispensing needle includes a conduit having a fluid channel to conduct a chromatographic flow, an interior wall that defines the fluid channel, an exterior surface and an endface through which the chromatographic flow is dispensed. The dispensing needle also includes a coating of a hydrocarbon material or a fluorocarbon material that is bonded to the endface. The coating is also bonded to at least a portion of the exterior surface that is adjacent to the endface and at least a portion of the interior wall that is adjacent to the endface. The coating operates to reduce a droplet volume of a liquid dispensed from the endface that may remain at the tip of the dispensing needle. Consequently, the concentration variation in a collected fraction due to a missing droplet or extra droplet is reduced.Type: GrantFiled: August 30, 2017Date of Patent: June 19, 2018Assignee: WATERS TECHNOLOGIES CORPORATIONInventors: Theodore A. Dourdeville, Joshua A. Burnett, James E. Usowicz, Marc E. Lemelin, Lucas O. Tiziani
