Automated rotary shear valves are designed for applications that require fast, consistent switching between flow streams. Connect valves to your PC or instrument via USB, BCD, serial port, or contact closure.

Use switching valves to switch one or more flow paths to a different destination. Nano scale models 02013-61 and 02016-04 deliver flow rates less than 100 µL/min. Use large bore models when flow rates are greater than 10 mL/min.

This Mass Rate Attenuator 100-000 stainless steel valve is an active splitting device (6-position, 4-port) that delivers a small aliquot of an

HPLC stream into a Mass Spec stream through a stator and rotor seal.
