Product Overview
Control Solenoid Valves
Lee Company highly reliable fixed and variable volume dispense pumps are ideal for positive fluid displacement applications in diagnostics, including reagent dispensing, aliquoting, probe washing, and sample preparation. Their ultra-fine resolution enables high precision volumetric aspirating and dispensing with exceptional accuracy. These pumps are maintenance-free and have an extensive life, so you can minimize downtime and position the pump where the system’s fluidics dictate, regardless of accessibility.
LHD Series Solenoid Valves
3-way HDI (High Density Interface) platform and are optimized for applications that demand ultra-low power, low heat, and small size. These valves are ideal for compact, battery powered pneumatic instruments such as portable oxygen delivery systems, environmental gas samplers, and other OEM flow switching devices. The rugged materials used help to ensure consistent long-term performance. The valves typically operate upto 250 million cycles on air, depending on the seal material and applications parameter. There are different versions for variety of applications.

The Vacuum Rated LFV Series MIV is a 2-way, normally closed, chemically inert solenoid valve that is ideal for fluidic circuits that will see both positive and negative pressures, such as pump inlet/outlet valves. The fluidic side of the valve is isolated from the coil and plunger by a chemically inert PFE (FFKM) membrane. Chemically inert, isolation style solenoid valves with zero dead volume used to flow aggressive fluids.
- 2-Way Design
- Low Internal Volume
- Voltage Flexibility: 12 & 24 Vdc
- Flow Capacity: 1000, 1300 and 2000 Lohms
- Multiple Mounting Styles
- Size Approx Dia 0.5” x L1.75” (depending on model)
- Available Seal Elastomers: EPDM, FKM and FFKM
- Operating life: 5 million cycles minimum

Xover Valve
XOVER® is an inert, internal pinch-tube isolation valve. It 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. 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.
