Microfluidic Inline Check Valve

Microfluidic Inline Check Valve (One-Way Valve)

The Microfluidic Inline Check Valve provides reliable one-way flow control in microfluidic and organ-on-chip setups.
With barbed connectors on both ends, it integrates seamlessly with soft tubing such as silicone or Tygon, allowing you to place the valve anywhere in your perfusion circuit.

This compact, low-dead-volume valve is ideal for preventing backflow from pumps or reservoirs, protecting delicate cell cultures from pressure spikes and unwanted reverse flow. It is particularly useful in recirculating systems, multi-channel chips, and long-term perfusion experiments. For research use only.
