This internal pinch-tube valve was designed to minimize reagent consumption, improve throughput, and maintain the vitality of cells. Xover configurations boast low internal volumes and a smooth, low shear, easily flushable fluid path on all models. The 3-way features a Y-shaped elastomer tube, which offers ultra-low carryover volume when switching between fluids. The valve is also offered in a 2-way Normally Closed or a 2-way Normally Open configuration and in a higher flow rate model (1000 Lohm) or lower internal volume model (3800 Lohm). 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, 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.
