Optimize Technologies OPTI-SEAL UHMW-PE Plunger Seal, for Waters Alliance/2690, 2695, 2790, 2795, 2/pk
Optimize Piston Seals are the longest lasting seals on the market. Machined from either of two proprietary polymer blends, UHMW-PE or ITB, Optimize Seals provide the ultimate in high pressure sealing capacity. For mostly aqueous buffered mobile phases, Opti-Seal™ UHMW-polyethylene is the wisest choice. Specially designed to be more resistant to abrasion and wear than standard polyethylene seals, they can last up to seven times longer under mostly aqueous conditions. Despite the UHMW-PE's durability, it has a coefficient of friction approaching that of PTFE. The homogenous polymer nature leads to less shedding, but when it does occur, a larger, more fibrous particle is produced which is easily caught by a filter frit. This item is equivalent to OEM part number WAT270938.
Waters Corp PerformancePLUS Check Valve Cartridge 2/pk
The PerformancePLUS™ Check Valve Cartridges are used with pumps that have the PerformancePLUS Cartridge Check Valve System installed. The PerformancePLUS Cartridge Check Valve System can be used as either an inlet or outlet valve in the Waters 1515, 1525, 515, and 600 HPLC pumps. The inlet check valves of the 2695, 2695D and the 2795 are also the PerformancePlus type. The check valve materials have been carefully specified for solvent compatibility with all HPLC mobile phases. The housing features a two-piece design that allows it to be removed so that the cartridge can be changed without disturbing the fitting on the housing.
