Check valves, which include a sealing washer, are easy to install using the optional Torque Wrench kit. For all PerkinElmer pumps an intermediate check valve is required. The input check valve, which is identical, should be ordered.
All PerkinElmer pumps contain a high and low pressure piston seal. In addition to the standard high pressure seal, we provide extended performance seals for more specialized requirements.
The MP2 (Micro Peristaltic Pump) provides better stability than standard peristaltic pumps. Roller configuration and precision machining minimizes gaps between rollers, resulting in even pressure points along the pump tubing. Reduced pump pulsation improves signal stability, data quality and detection limits.
MP2 (Micro Peristaltic Pump) for integration into PerkinElmer NexION inductively coupled plasma mass spectrometers (ICP-MS) provide better stability than standard peristaltic pumps.
Biocompatible Inlet/Intermediate Check Valve for PerkinElmer Series200, 410, 250, Biocompatible Integral 4000 and Model 620 Pumps built after March 1, 1987
All PerkinElmer pumps contain a high and low pressure piston seal. Whenever replacing the low pressure seal, the Low Pressure Seal Back-Up Ring should also be replaced.
