The Xover solenoid valve (photo) is designed to switch quickly and efficiently between samples, reagents, cleaning solutions or calibrants. The Xover valve features a Y-shaped elastomer tube in a three-way configuration, which results in a design that combines the flow path of a pinch valve with the versatility and maintenance-free performance of a chemically inert isolation valve. This means that it is easily flushed and ensures fast, efficient fluidic performance with lower power consumption, according to the manufacturer. The Xover’s features make it suitable for a wide range of applications, including scientific instrumentation, drug discovery, analytical chemistry and any fluidic application where low internal and zero-dead volume and inert materials are critical. — Lee Products Ltd., Buckinghamshire, U.K.
