The technology is a multi-channel valve solution that prevents cross-contamination between fluid flows, using only one actuator to control multiple channels. This valve system is ideal for biological sampling applications where contamination risks are high, and weight, space, and power usage must be minimized.

Description

In fluid handling applications, cross-contamination between samples is a significant issue, particularly in remote or high-precision environments. Traditional valves, pinch or spool valves, either do not allow for multi-channel operation or introduce contamination risks. This provides a flexible tube-based system where only one actuator is needed to open or close multiple channels without interfering with the fluid flow itself. It is especially suited for remote applications where the valve system can handle multiple configurations and reduce the need for numerous actuators, conserving energy and space.

Benefits

  • Prevents cross-contamination: Ensures fluids are handled separately without mixing, preserving sample integrity.
  • Enhanced flow control: Provides precise and controllable flow management for biological or chemical processes.
  • Cost-effective: Reduces the need for additional equipment or labor, such as field personnel, in remote sampling applications

Applications and Industries

  • Environmental DNA sampling (eDNA): Used for stream water analysis to identify species and monitor biodiversity without risking contamination between samples.
  • Wastewater sampling: Helps in monitoring viral presence in water, such as during public health assessments. 
  • Biological and chemical flow control: Suitable for lab-on-a-chip applications where precise, contamination-free fluid handling is required.
