Oak Harbor, WA, February 24, 2012 — IDEX Health & Science (Booth 2729) offers instrument manufacturers increased pump performance in a new Check Valve for UHPLC systems. Created to maintain pressure in alternating-phase pumps, the lower cracking pressure of the new Check Valve was designed for faster response against competitive models. The patent pending ball cage design facilitates faster response times and improved flow characteristics through the check valve, which allows for less carry over by removing un-swept volume. “All check valves exhibit some leakage,” explained IDEX Health & Science Product Manager Mike Mainvielle; “In the closed position, at these extreme pressures, some leakage in the nanoliter range is expected, and that’s how check valves are rated.” IDEX Health and Science Check Valve materials are processed in-house enabling the control of critical dimensions, features, and surface finishes.

New Reusable One-Piece Fittings from IDEX Health & Science Increase Efficiency and Reliability in UHPLC

Oak Harbor, WA, February 10, 2012 — Breaking through constraints of the past that required a discrete stainless steel fitting mated to each receiving port, the new VHP-320 Fitting for UHPLC from IDEX Health & Science incorporates a one-piece design in which the ferrule cannot separate from the nut, yet allows the fitting system to be reused up to 10 times in multiple ports.

The design of the VHP-320 fitting assures biocompatibility with a proprietary PEEK-blend (PK) tip ferrule in contact with the flow path. Reusable fittings reduce system downtime caused by changeovers associated with columns, sample loops, tubing, and inline filters. An expanded line of new tightening tools for achieving optimal torque with the VHP fittings is also available. Intensive product testing has demonstrated there is no increase in carryover after 2000 injections when using the Reusable fitting.
