And they should perform as well or better than the original manufacturers' design.
To meet these exacting standards, Bay Scientific proudly offers the OPTI-MAX cartridge check valve system, from Optimize Technologies.
OPTI-MAX Check Valve
Cartridge and Housing
Use the same OPTI-MAX cartridge in pumps from different OEMs
A single OPTI-MAX cartridge is interchangeable across multiple pump brands, and will function in either the inlet or outlet position. The same OPTI-MAX 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 emergency maintenance needs.
Most OPTI-MAX check valve housings are supplied in a Free-Turn configuration - the thread that tightens the housing into a pump head spins independently from the inner housing body, where the connecting tubing and cartridge join the housing. This allows you to remove a check valve housing without having to first disconnect the connecting tubing. With OPTI-MAX, you can completely replace a check valve cartridge in two minutes!
Remove check valves without removing tubing, with Free-Turn™ Housings
OPTI-MAX Cartridges are available in a choice of materials
OPTI-MAX cartridges are available in two different body materials, and with two different ball/seat options. Cartridge bodies can be made with stainless steel or PEEK, while ball/seat sets are available in all-ceramic, or in ruby/sapphire.
OPTI-MAX cartridge check valves are available for almost all major brand HPLC systems. Locate OPTI-MAX check valves and other replacement components for your system quickly and easily - click on the "Find a Check Valve" link.
