The ASI FlatLine™ Pulse Damper combines performance and reliability in a simple, easy to use housing. Standard 10-32 inlet and outlet ports allow quick connection into virtually any HPLC system. Solid core technology provides reliable long term operation without the down time associated with ruptured or leaking membrane dampers. Custom sizes and additional features like integral prime/purge valve available for the OEM market.

Although similar to the standard ASI FlatLine™ Damper, the HC (High Capacity) features a bimodal damping mechanism which includes solid core and dynamic spring deflection. This combination increases damping efficiency over a wider pressure range. The HC is particularly well suited for damping at low pressures, below 500 PSI.

The ASI in-line check valve incorporates many of the innovations of our self-priming replacement check valves.  It is a rapid closure cartridge valve that features very low resistance to flow, low internal volume, and operates independently of gravity.  It is protected from solvent contamination by a 1/4" diameter 2 micron frit, and features crush-proof construction.  The valve may be used whenever fluid flow needs to be restricted to one direction. Applications include prevention of post column derivitization fluids from back-flowing into the column in the event of mobile phase pump failure.  This valve is also available in a high temperature version that will operate at up to 125º C and 5000 PSI. (Please call for more information).

Universal fittings and unions are compatible with most HPLC fittings such as Parker, Swagelok, Valco, Upchurch, Beckman, and Waters, when initially assembled with new ferrules. All components are manufactured from 316 stainless steel, and are cleaned and passivated. Unions come complete with 1/16" compression fittings.

Solvent Filters

It is essential to use a solvent filter at the pump intake to insure reliable operation of the check valves and other pump system components. We recommend a 10 micron filter for most analytical applications. For flow rates in excess of 10 mL per minute, we recommend a 20 micron filter to avoid pump cavitation. ASI filters are designed to slip inside either 1/16" ID or 1/8" ID tubing, and are made from 316 stainless steel.

1/16 " OD Stainless Steel Capillary

ASI Capillary tubing is made from 316 stainless steel and is available in 25 ft. lengths; other lengths upon request. The tubing ID should be passivated after cutting as follows: 20 % nitric acid for 30 minutes, followed by distilled water rinse.

Teflon (TFE) Tubing

Teflon Tubing provides unmatched solvent resistance for low pressure applications.

PEEK Tubing

PEEK can be substituted for stainless steel tubing when contact with metal is a concern. It is inert to most HPLC solvents, will withstand intermittent operation up to 5,000 PSI, and continuous operation at 4,000 PSI. PEEK tubing should not be used at these pressures with DSMO,THF, or methylene chloride.
