Turning valves embedded on microfluidic chips allow the targeted distribution of liquids and gases in channel networks, by actively opening and closing channels and by metering liquids. In instruments the valves are operated in an automated manner through turning the valve body in previously defined increments. They can be operated either manually with a little valve actuator or mechanically with microfluidic ChipShop’s latest ChipGenie® edition TV.

These chips allow to evaluate the metering on chip and in the valve body with the help of a turning valve and for  directing of liquids on chip.
