Microfluidic Valves from LabSmith

Small, reliable, programmable—and affordable.

LabSmith’s microfluidic valves make building and automating microfluidic circuits fast and easy. Simple to program, and a fraction of the size and cost of competitive valves, LabSmith microfluidic valves are ideal for research and OEM applications.

Microfluidic Valves - LabSmith uProcess Automated Microfluidic Valves

Each LabSmith microfluidic valve features:

  • simple programming through uProcess scripting software
  • fast, reliable geared switching for long life
  • extremely small swept volumes to minimize waste and enable high throughput
  • twist-in connections for leak-free operation
  • interface for 1/32” OD, 1/16″ OD or 360 micron OD capillary.

LabSmith automated valves are a key part of the uProcess family of automated products. uProcess components simplify construction and control of microfluidic systems. Components include syringe pumps, selector valves, pressure and temperature sensors, temperature controllers and more. uProcess software makes it straightforward to generate automated scripts to control both simple setups or complex lab automation.

All microfluidic valves are compatible with LabSmith’s CapTite™ interconnect products for building and rebuilding micro- and nanofluidic circuits.
