Solenoid Valves

Xover® 2- & 3-Way Isolation Solenoid Valve

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.

1Typical cycle life on water; actual cycle life will vary depending on application conditions.
2Valves can pass soft, spherical media, such as cells, within the listed passage size limitations. To protect against hard particulate contamination, filtration of 50 microns or finer is recommended for 1000 Lohm models, or 35 micron or finer for 3800 Lohm models.
3Typical response time based on water flow at 10 psid. Actual response times are dependent upon system conditions and may vary. The response is measured by the presence of flow; armature movement occurs faster than flow. Extended periods of inactivity may impact the valve's initial response time.
4Xover is designed to operate under continuous duty at the rated voltage ± 5%.

Installation & Accessories

MOUNTING

Two through holes 0.098 of an inch in diameter, 0.63 of an inch nominal spacing molded within the valve body, compatible with #2 fasteners. Refer to the image below for a compatible mounting hardware kit.

PORT CONNECTIONS

062 MINSTAC style compatible with 062 MINSTAC system of fittings and components. Select part numbers are listed below. For a full list of compatible tubing assemblies and components, see Section N (MINSTAC).

¼-28 FB ports are compatible with commonly available fitting systems. For 3-way configurations, ensure that nut diameter is 0.31 of an inch (7.9 mm) or less to avoid interference. See pages N10-12 for stock tubing assemblies.
