OPTI-MAX® Cartridge Check Valve Systemhplc pump check valve

The check valve is a critical pump head component, and is instrumental in the delivery of stable, pulse-free flow rates.  The OPTIMAX® Cartridge Check Valve System was designed to offer superior performance and versatility, and is manufactured to the tightest specifications in the industry. One OPTI-MAX replacement cartridge will fit multiple brands of pumps, and can be used in both inlet and outlet OPTI-MAX housings. Housings are available for all major HPLC pump brands.

OPTI-MAX Cartridges: A Universal Solution

A single OPTI-MAX cartridge is interchangeable across multiple pump brands, and will function in either the inlet or outlet position. The same cartridge will fit into pumps made by Shimadzu, Waters, Hitachi, and most other OEM solvent delivery systems, allowing you to minimize the number of spare check valve cartridges in your inventory. OPTI-MAX Cartridges are available in PEEK or stainless steel, loaded with precision-matched ball and seat sets in ceramic or ruby/sapphire.Three ball/seat sizes are available, providing optimal performance for microbore, standard and extended flow applications.The performance of a check valve can only be as good as the integrity of the seal made between the ball and seat inside it. All ball and seat sets used in OPTI-MAX cartridges are precision-matched to the most exacting standards in the industry, and must pass Nitrogen leak tests four times more stringent than those specified by most other manufacturers.

optimax cartridges pump

OPTlMAX® cartridges are now available with both ruby/sapphire and ceramic ball and seat. Ceramic is 50% greater in density than the ruby ball commonly used. The heavier ball should seat faster, improving performance in some applications.

peek and stainless steel check valve cartridge

PEEK and Stainless Steel cartridges are available in standard, low flow rate and higher flow rate versions.
