SSI Valves

Each port in this valve can be connected to pressure, as in stream-splitting, or when connecting an in-line pressure gauge (open valve to read pressure, seal off to prevent contamination). The side vent model can replace the injector bypass valve on Altex, LDC, PerkinElmer, Spectra-Physics, or other chromatographs, and is recommended for all general applications. The bottom vent model replaces the bypass valve on a Varian 5000 chromatograph. For 1/16 in. tubing; 1/4-28 (SSI style) fittings included. Rated to 15,000 psi (1,054 kg/cm2).

SSI LO-Pulse Damper

A pulse damper controls pump pulsations for a more stable baseline. The LO-Pulse damper is a patented unit compatible with single piston reciprocating HPLC pumps (Altex 110A, Eldex pumps, LDC Mini-Pump VS, SSI Models 200 and 300, etc.). At pressures from 500 psi to 6,000 psi (35-420 kg/cm2), it improves precision of quantitative analyses and detection limits for trace sample components. Fittings and instructions included.
