HPLC
Stream selector

1/16" Valco ZDV fittings, 0.40 mm ports (.016")
Model C5

The Cheminert® Model C5 HPLC stream selector valve selects and isolates one of 4 to 10 streams, with the remainder dead-ended.

The C5 valve is the backbone of the Cheminert HPLC column selector system, which includes two stream selection valves mounted on a single microelectric actuator.

An optional flowpath, Model C5F , the flow-through version, is similar to the C5 but its non-selected streams continue flowing through individual outlets. 3, 4, and 5 positions are available.
