LO-Pulse®PulseDamper
The LO-Pulse® PulseDamper is a patented, wide-dynamic-range 316 stainless steel device that smooths
pulsations andmaintains constant flowat systempressuresup to6,000psi (41,369kPa).The flowpathvol-
ume is only 0.9mL and the path is efficiently swept, eliminating solvent memory effects when changing
mobilephases.
TheLO-Pulse®pulsedamper also is available in a space-saving, economical kit that includeshardware for
mounting thepulsedamper on abracket, or for installing feet on it for bench-topuse.

BackpressureRegulators
Backpressure regulators can improvedetectorperformancebypreventingbubble formation in thedetec-
tor flow cell. They also are useful in post-column reaction lines and between detectors and fraction
collectors inpreparatorywork. Regulators are superior tomore specific alternative solutions, like small-
bore tubing, inwhichpressure varieswith flow rate.
Our end-of-lineand flow-throughbackpressure regulators areadjustable toassure constant backpressure
over a wide range of mobile-phase viscosities and flow rates. The end-of-line model is available with
1/4-28plastic flange-type fittings or high-pressure

FlatLine™PulseDamper
• Rupture-proof, nodiaphragm—minimal riskof failure or leaks.
• Clean flush-out design—no sample carryover.
• Low internal volume—negligible effect on analyte bandwidth.
TheASIFlatLine™PulseDamper combinesperformanceand reliability ina simple, easy-to-usehousing.
Standard 10-32 inlet andoutlet ports allowquick connection into virtually anyHPLC system. Solid core
technology provides reliable long-term operation without the down time associated with ruptured or
leakingmembrane dampers. 600–700µL internal volume at ambient pressure.
