PerkinElmer* Check Valves for Series 200 Pump

Check valves allow solvent to flow in only the desired direction. They should be cleaned or replaces periodically in accordance with a preventative maintenance schedule. For all PerkinElmer pumps an intermediate check valve is required. The input check valve, which is identical, should be ordered.
Note: These valves are only for models built after March 1, 1987.
