Inline cartridge check valves are designed to limit flow in one direction and deliver a low cracking pressure. Ideal placement for these valves would be on the effluent side of the column to prevent post-column derivatisation agents from flowing back and poisoning the column if the HPLC mobile phase pump were to shut down.

• Low cracking pressures
• Designed to limit flow to one direction
• Pressure rating up to 1000 psi (69 bar)
