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).

ColumnShield Precolumn Filter

PrimeLine ColumnShield precolumn filter provides economical protection from the harmful effects of sample and mobile phase particulates on modern HPLC columns. The disposable filter was engineered to maintain the efficiency of high performance columns assuring insuring no loss of critical resolution. With its simple design, the filter installs in any analytical column or guard column in seconds and is leak tight to 5,000 PSI. To install simply hand tighten the filter as you would with any fingertight fitting while holding the column stable.

특  징

Economical protection against micro-particles

Extends HPLC column lifetime

Negligible effect on column performance

Universal fit, connects directly to column

Fingertight to 5,000 PSI

High Capacity In-Line Filters

This filter features a clean-swept internal volume and a large 2.2 cm2 filter area that will provide a long service life. Filter cartridges are available in 0.5 micron and 2 micron porosity,and are both interchangeable and replaceable. Total internal volume is 100 μL for 0.5 micron filter, and 120 μL for 2 micron filter.

Low Volume In-Line Filters

Recommended for applications where system volume must be kept to a minimum. Full use of the filter surface is maintained by a 5° entrance cone. The 0.25” diameter replacement filter cartridges are available in 0.5 micron and 2 micron porosity, and have a 0.32 cm2 active area. Total internal volume is 14 μL for the 0.5 micron filter and 18 μL for the 2 micron filter. The 0.062” replacement filter is 0.5 micron with 2 μL internal volume.

In-Line & Direct Connect HPLC/UHPLC Column Filters

PrimeLine direct connect precolumn filters provide economical protection from the harmful effects of sample and mobile phase particulates on modern HPLC and UHPLC columns. The PrimeLine precolumn filter was engineered specifically for use in high throughput and routine HPLC separations where mobile phase and sample contamination cause a decrease in column performance or premature column failure. The low swept volume of the PrimeLine filter maintains the efficiency of high performance columns assuring a negligible loss of critical resolution. With its simple design, the PrimeLine filter installs in any analytical column in seconds and is leak tight to 15,000 PSI. Simply finger tighten initially, then wrench tighten an additional 1/4 - 1/2 turn.

특  징

Cost effective way to extend column lifetime

Replaceable filter element

Negligible effect on column performance

Universal fit, connects directly to column

Leak tight to 15,000 PSI

UltraShield HPLC/UHPLC Precolumn Filter

UltraShield direct connect precolumn filters provide economical protection from the harmful effects of sample and mobile phase particulates on modern UHPLC and other high resolution HPLC columns. UltraShield was engineered specifically for use in fast, high efficiency separations requiring high mobile phase velocities and ultra high pressure. UltraShield maintains the efficiency of these high performance columns assuring no loss of critical resolution. With its simple design, UltraShield installs in any analytical column in seconds and is leak tight to 15,000 PSI. Simply tighten the filter with a wrench until it is snug, followed by an additional 1/4 turn.

Guard Column HPLC/UHPLC Hardware

The PrimeLine direct connect guard column provides economical protection from the harmful effects of sample and mobile phase particulates and soluble contaminants on modern HPLC and UHPLC columns. The low swept volume of the PrimeLine guard column maintains the efficiency of high performance columns assuring a negligible loss of critical resolution. With its simple design, the PrimeLine guard column installs in any analytical column in seconds and is leak tight to 10,000 PSI.
