Rheodyne Six-Position Switching Valve, 7060

Rheodyne's Six-Position Switching Valves make complex HPLC analyses easier. Two manually operated six-position valves allow convenient selection among six columns for different analytical methods on the same chromatograph. The advantages of using these valves over manually changing columns are: immediate selection, no wear on fittings from repeated tightening, and having both ends of the off-line columns sealed by the valves (keeping them on stand-by for future use).
