  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.

You can download and run the Scratch control program from the scratch website.
