The Low cost PEEK LO-Pulse Dampener is the same model as used in the Model LP-21 PEEK Lo-Pulse Dampener but without the outside case. It is a space-saving, economical kit which includes hardware for mounting the pulse dampener on a bracket, or for installing feet on it for bench-top use.

The patented wide dynamic range pulse dampener is designed for use with single piston reciprocating HPLC pumps and maintains a constant flow at system pressures from 500 to 6,000 psi (3,447 to 41,369 kPa). It uses 1/16" 10-32 coned fittings.

The LO-Pulse pulse dampener reduces pulsations by compressing a fluid held within the bottom cavity of the unit. This fluid is isolated from the LC mobile phase by a durable but flexible inert diaphragm. As the HPLC system pressure increases, fluid in the bottom chamber is compressed. When the LC pump piston is retracting, the compressed fluid expands maintaining system pressure and, more importantly, keeps the mobile phase flowing at a constant rate. When the system pressure is at its maximum allowable pressure (6,000 PSI), the volume of mobile phase in the LO-Pulse is only 0.9 mL.

The noise level in the detector resulting from pump pulsations can significantly affect precision in qualification and the detection limit of trace components. The LO-Pulse Dampener smooths pump pulsations and maintains constant flow in flow sensitive detectors.
