Microfluidic valves

Unique valve geometry designed for ultra-low internal volume and no dead volume

A microfluidic valve, or also called microvalve are basic components used in microfluidic devices to handle liquids through different valve ports.

Minimized reagent consumption and decreased experiment’s cost

ULTRA LOW CARRYOVER VOLUME AND LOW INTERNAL VOLUMES

We provide small channels diameters available down to 0.5 mm which decreases the total volume in the system to save reagent consumption.

Our unique microvalve design can include several port stages which significantly decreases the internal volume (total volume in the system) and allows fast liquid switching thanks to its ultra-low carryover volume down to 1.5µl (volume of liquid that will be mixed with the next liquid) compared to other microfluidic valves on the market.

High cleanability and prevented cross contamination risks and biofilm formation

NO DEAD VOLUMES

Our manufacturing process is Swiss home-made and respects high-quality standards and a high precision degree in the material cut, allowing our microvalves to have no dead volume (which is the part of the liquid out of the flow path and stuck in the system). The zero dead volume feature allows less contamination between liquids and can be suitable for demanding protocols especially in biological applications which require no biofilm formation in the system and high cleanability.

In addition to this ultra-precise manufacturing process, all microfluidic valves are going through a manual final inspection to remove small filaments visible at microscope.

Standard microfluidic connections and easy OEM integration in your device

PLUG AND PLAY

Our microvalves can be easily mounted or changed on the RVM Electric Rotary Valve, and the SPM OEM Microdispenser. There are only two screw to dismantle on the motor system.

Our microfluidic valve ports are designed for high compatibility with standard fluidic connections, allowing them to be easily integrated in your protocol and your custom microfluidic experiment.

High chemical compatibility and strong stability to mechanical movements 

OPTIMIZED MATERIALS

Our microfluidic valves plugs can be available in different materials:

  • PTFE (Polytetrafluoroethylene, also known under the trade name equivalent to the Teflon®). This material is chemically inert and therefore highly compatible with to most used solvents, with its excellent stress resistance.
  • UHMW-PE (Ultra-high-molecular-weight polyethylene). This material has a strong resistance to mechanical movements, and is a very tough material, with the highest impact strength of any thermoplastic presently made.
