This inert, internal pinch-tube valve was designed to minimize reagent consumption, improve throughput, and maintain the vitality of cells. Available with ¼-28 flat bottom or 062 MINSTAC® fluidic ports, Xover boasts low internal volumes and a smooth, low shear, easily flushable fluid path on all models. The 3-way features an innovative Y-shaped elastomer tube, which offers ultra low carryover volume when switching between fluids. This tube also allows for single-plane flow through the valve, keeping fluid flow laminar and minimizing mixing. The valve is also offered in a 2-way normally closed or a 2-way normally open configuration. Unlike traditional external pinch valves, Xover is durable across a long life and switches consistently in less than 40 ms. It is ideal for applications in flow cytometry, gene sequencing, spatial biology, microbioreactors and analytical chemistry. Each valve is customizable and 100% tested to guarantee performance.

The Lee Company has developed the Lohm Laws for defining and measuring resistance to fluid flow. The Lohm is defined such that 1 Lohm will flow 100 GPM of water with a pressure drop of 25 psi at a temperature of 80°F.
Always verify flow calculations by experiment.
