Xover® is a breakthrough in quick and easy flow selection with its innovative pinch-tube design and low carryover volume. Learn how this component combines the flow path of a pinch valve with the versatile, maintenance-free performance of a chemically inert isolation valve to power critical applications in high-tech medical and scientific instruments.
The Lee Company offers small precision fluid control solenoid valves for a wide variety of diagnostics applications, including sample prep, amplification (PCR), detection, and sequencing. Use our solenoid valves to precisely control buffer fluids, inject reagents directly into a well plate, or pneumatically control flow through a microfluidic cartridge without compromising reliability. Our solenoid valves are engineered solutions designed to overcome key challenges, such as leakage, internal and dead volume, and switching response times – without sacrificing system-level performance requirements. If you want to perform precise and reliable diagnostics, you need fluid control components that deliver on all accounts, without compromise.
Engineered using long-lasting materials, each valve is 100% functionally tested to ensure reliable, consistent, long-term performance. The Lee Company can customize valve performance to meet specific application requirements including actuation voltage, porting conditions, operating pressure, flow rates, seat leakage, response time, seal materials, and more. Please contact your local Lee Technical Sales Engineer with your custom needs.
Control solenoid valves are used to flow air or gas in pneumatic systems where versatility and reliability cannot be compromised for fast response times or low power operation. Available as a 2-way or 3-way design in various mounting styles, these compact valves are easily manifold mounted or soft tube connected, making them the perfect solution for applications where many valves must be designed into the smallest space possible. In addition to conventional solenoid valves, we offer magnetically-latching solenoid valves that consume far less power, which helps conserve energy in battery-powered applications.
As their name suggests, dispensing solenoid valves are designed to dispense small volumes of liquid ranging from nanoliters to milliliters. Available as a 2-way, normally closed, axial flow configuration, our dispense valves feature high-speed operation that delivers drop-on-demand performance to accurately regulate fluid flow. The compact design enables dispensing valves to be easily integrated into the tightest spaces. High pressure and high-temperature capabilities allow viscous fluids to be accurately dispensed, and chemically inert materials increase compatibility for use with aggressive fluids.
Isolation valves are used when aggressive fluids come into play. Available in a diaphragm or pinch tube model, these valves are engineered so that the sensitive internal solenoid components are separated from the flow path. This dramatically extends the lifespan of your instrument without compromising performance and reliability. Lee isolation valves come in 2-way or 3-way designs and in multiple mounting styles, providing engineers with flexibility for integration into the smallest space possible. The low internal volume and fast switching response of these valves make them easy to flush between cycles for efficient fluid control.
