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.

Optimize Technologies ITB™ PTFE Plunger Seal, HP/Agilent 1050, 1100, 1200
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, PTFE-based Improved PTFE Blend (ITB) seals are a superior choice for applications with elevated temperatures, high organic content, or when the broadest possible solvent compatibility is required. ITB™ seals tend to be softer than those made from UHMW-PE, making them more forgiving at high pressures where piston side-loading or misalignment may occur. This softer nature also leads to more shedding, but the ITB™ proprietary blend is designed to shed particles that are large enough to be caught at the surface of a standard 2µm frit, not embed within it. This item is equivalent to OEM part number 5063-6589.

Perkin Elmer US LLC 50µL PEEK Sample Loop for Model 9725 Rheodyne Injectors
PEEK Sample Loops avoid many of the problems associated with stainless steel sample loops. Metal loops will often absorb sample components resulting in inaccurate quantitative results. In addition, metal loops may be corroded by high-salt buffers and chloride salts. Sample Loops are made from PEEK tubing andfittings. PEEK (Poly-Ether-Ether-Ketone) is a mechanically strong,chemically inert polymer ideal for HPLC applications where metalsurfaces may interact with mobile phase or sample components. Each Sample Loop is supplied with two PEEK hex-head nuts andferrules. These fittings grip the tubing in two locations for amore reliable connection. Rheodyne Sample Loops are made of natural PEEK. This means nodye leaching into your sample. Like metal loops, the size designations of PEEK loops are nominal. The actual volumes can differ from the theoretical designations because of the 0.05 mm (0.002) tolerance of the tubing bore. Accuracy of largePEEK loops (0.8 mm, 0.030 bore) is about 14%, i
