 ====== Servo valves ======
+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

+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).
