These are used to enable diverse techniques in liquid handling. This valve technique uses a disposable stop cock valve and a standard servo motor. Now this works with these cool polypropylene stopcock valves

Steps in putting a valve together:

Steps in putting a valve together:

First start with the smallsyringe_valvesupportmodule_plate() smallsyringe_valvesupportmodule_plate.stl

Many servos like this are available on Amazon, you can also find them at your local dump

Connect the stop cock connector onto the servo horn valveconnectpart.stl

Connect the valvemountplate_screwattach_smallersyringe_vertical_attach() part is used to hold the stop cock in place as the servo horn turns valvemountplate_screwattach_smallersyringe_vertical_attach.stl

Many servos like this are available on Amazon, you can also find them at your local dump

Secure the valve so only the handle moves when the servo horn turns valvemountplate_screwattach_smallersyringe.stl

For an 8 channel system, use 8 valves (1 valve per syringe). Here is an image of a plate that holds 4 valves. With a RaspberryPi (not showing the Pi-Hat servo shield).
