Solenoid valves open and close with low voltage relays
We illustrate the use of the solenoid valve and a small reservoir, controlled by the graphical programming language "Scratch" (scratch.mit.edu) and a solenoid valve to make the first part of an automated immunohistochemictry platform.
The first step in making an IHC platform would be to de-paraffin (wash) a glass slide with a xylene substitute.

You can download and run the Scratch control program from the scratch website.
Credit for the "Axe-uator" (linear actuator) is given in the text and is viewable on Youtube.
Step 1: Step 1: Parts List
We've kept the cost of the parts to a minimum. The entire project setup is less than 20$, without the cost of the
Lego WeDo robotics kit (for use with the Scratch programming language).
Step 2: Step 2: Assemble the valve and reservoir
Step 3: Step 3: Attach the Solenoid Valve
Two would have been better (a little more stable).
Step 4: Step 4: Make the "Bath"
Step 5: Step 5: Scratch Programming
Step 6: Step 5: Run a test
Video of the valve in action as well as an "on-screen" view of how to set up the Scratch program can be seen.
