Optimize Technologies Sapphire Plunger, HP/Agilent 1050, 1100, 1200

Pistons are, by design, a consumable part of the HPLC pump and should be replaced on a regular preventative maintenance schedule. To maintain peak performance and avoid unplanned downtime, sapphire pistons require inspection every six months with yearly or as-needed replacement. Optimize sapphire pistons offer optimal concentricity and resistance to wear. Each sapphire rod is specifically cut in relation to the grain of the crystal lattice, yielding maximal resistance to breakage and superior wear characteristics. Attachment of the rod to the piston ferrule is performed through a proprietary process ensuring concentricity. This is an important, often overlooked procedure parameter that has a direct effect on seal lifetime. This item is equivalent to OEM part number 5063-6586.

Optimize Technologies OPTI-SEAL UHMW-PE Plunger Seal 5mL S/SC Head [Gilson, Rainin HP, HPX, HPXL, SD200/300], 10pk

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.
