We developed our Rotary Shear Valves in tandem with the evolution of HPLC offering solutions to the ever changing fluidics landscape. With the introduction of elevated system pressures, aggressive chemicals, and decreasing fluid volumes the need for highly precise fluid control and delivery is imperative. Today, many other disciplines use Rotary Shear Valves for their versatility, reliability, repeatability, and easy maintenance.

Our Stand Alone Valve Products offer more sophisticated functionality. Versatile, they can be added to your existing instrument or in stand-alone lab configurations. Choose an automated valve if the application requires fast, consistent sample injection or flow-stream switching. Some other advantages of automated valves include control options (PC- or instrument-triggered), higher pressure operation, valve-position feedback, or very small flow paths. Note: For Valves please allow an additional 8 days lead time.

Our valve accessories include a variety of products that work with and are specific to our valve mechanics. From Sample Loops, driver boards, or to mounting brackets we offer a wide array of accessories to meet your system requirements. We also include tools that work specifically with our valve and valve components.

Micro Fittings are specifically designed for use with microferrules. They are manufactured from a proprietary PEEK blend (PK) which allow them to be used at higher temperatures (up to 200° C) and higher pressures ideal for UHPLC applications.

Our reusable VHP Fittings are capable of up to ten repeat assembly cycles with no impact on pressure holding ability or carry-over. They are pressure rated up to 25000psi making them ideal for UHPLC applications. They are designed for the most commonly used ports in UHPLC that being 10-32 threads for 1/16 inches outer diameter tubing and M4 threads for 1/32 inches outer diameter. They are manufactured from stainless steel and proprietary PEEK polymer blend (PK) ensuring strength and chemical compatibility.

These fittings are ideal for UHPLC applications. Our all Stainless-Steel VHP Fittings include a unique ferrule system with two compression points to provide twice the grip of a standard ferrule allowing pressure up to 30000psi. This design also allows the bite on the tubing to be less concentrated and does not restrict the inner diameter. The ferrules for 1/16 inches outer diameter tubing and 10-32 coned ports are two pieces, while the grooved ferrule for 1/32 inches outer diameter tubing and M4 coned ports is a one-piece design for easier handling, but it will act as two pieces with double compression on the tubing as it is tightened down.

Our UHPLC fittings are manufactured from a proprietary PEEK blend (PK) which allow them to be used at higher temperatures (up to 200 °C) and higher pressures. The VHP PK One-Piece fittings are available for 10-32 coned, 6-32 coned, or M4 coned ports, and Two-Piece fittings are available to connect either 1/16 inches or 1/32 inches outer diameter tubing into 10-32 coned ports in multiple styles. VHP MicroFerrules are made from a proprietary high performance PEEK polymer blend, a material which is unique in its ability to enable the use of capillary tubing in UHPLC environments. The new high pressure MicroFerrules are available for use with 1/32 inches or 360 μm outer diameter tubing, and they are incorporated into several of our VHP products for capillary tubing.
