Smooth pump pulsations and maintain a constant flow in flow sensitive detectors with Greyhound's range of pulse dampeners.  Greyhound offers a selecion of highly efficient pulse dampeners for use with a wide range of HPLC Pumps, (also known as pulsation dampeners and pump inlet stabilisers).  When liquid pressure falls in the piping system, a pulsation dampener supplies extra pressure to the discharge between the pump strokes by displacing liquid by means of diaphragm movement.
