Optimize Technologies OPTI-MAX Standard 1/8" Diameter Ceramic Ball & Seat, PEEK Replacement Cartridge, 2/pk Fits xx-48-xxxxx xx-58-xxxxx OPTI-MAX Housings
Opti-Max™ Check Valves are manufactured with ball and seat sets that are individually matched to ensure a lock-and-key fit. This guarantees 3 bubbles per minute or less in the standard nitrogen bubble test. Optimize has also minimized the ball travel distance within the check valve resulting in quicker seating and more accurate pump metering. A single cartridge is interchangeable across multiple pump brands, and will function in either inlet or outlet position. The same replacement cartridge will fit into OPTI-MAX™ housings for pumps made by Waters, Shimadzu, Agilent/HP, and most other OEM solvent delivery systems. This allows you to minimize the number of spare check valve cartridges you keep on hand, and dramatically reduce the cost of inventory required to cover your maintenance needs. This check valve shares the same external dimensions with 1/32" and 1/16" cartridges and fits all OPTI-MAX™ housings except xx-6x-xxxxx.
Optimize Technologies OPTI-MAX™ Outlet Cartridge for UHPLC Pressures (20,000 psi+), 1/16" Ceramic Ball & Seat, SS Cartridge, HP/Agilent 1050, 1100, 1200, 1220, &1260
Opti-Max™ Cartridge Check Valves are designed to offer maximum performance and ease of use. From the sharp, consistent threads on OPTI-MAX™ custom housings, to the exacting standards used to match ball/seat sets in OPTI-MAX™ cartridges, every aspect of design and manufacturing reflects an unavoidable fact: when it comes to reliable check valve operation, quality and precision make a big difference. OPTI-MAX™ check valves offer many advantages over OEM check valve systems, and are better designed, better made and more reliable than any other after-market check valve product. Additionally, OPTI-MAX™ Free-Turn™ housings can be removed with the tubing still attached, accelerating check valve maintenance while reducing fitting wear. This item is equivalent to OEM part number G1312-60067.

Optimize Technologies PTFE Plunger Seal, Green Premium Grade, Agilent/HP 1050, 1100, 1200, 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, 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 µm frit, not embed within it.
