Buffer salts and metals from the HPLC system become imbedded on the surface of the piston seal and gradually wear the surface of the piston rod. Worn regions on the rod will quickly destroy the pump seals. In turn, the seal material gets trapped on the frit at the head of the column, which leads to increased system pressure and/or irregular or poor peak shape. As the piston continues to wear, a leak may develop at the pump.

• Precut, micropolished tubing and preseated fittings for quick, easy maintenance of your Agilent HPLC systems.
• Meet or exceed manufacturer's performance.

Over time the piston seal in every HPLC system becomes worn and must be replaced. Our piston seals are constructed of Teflon® material with an additive that reduces their tendency to “cold flow” and improves their wear characteristics. Teflon® seals are more resistant to any HPLC solvent than UHMWPE seals, but they are less wear-resistant and rugged. For Agilent 1050 and 1100 HPLC systems.

ASI subjects each valve to a rigorous series of tests, including self-priming capability, which means you typically won’t need a syringe or draw-off valves to prime your pump. A high-pressure test ensures that the valve will not leak, even at pressures up to 12,000psi (82,737kPa). A low-pressure test verifies that the valve closes properly, even without a high backpressure force. The cartridge design allows easy, convenient replacement of worn or damaged valves.
