This really isn't something that requires an instruction manual ― it's a cork. You place it in a test tube if you intend on shaking the contents. How do you use it? Again...not a complicated process. Fit it inside the test tube.
I think you might be talking about Robert Hooke, he first discovered cells by looking at cork from a cork tree under a microscope, he did not actually use the cork as an apparatus. Therefore i think this falls more under biology. However if that is not what your talking about then I honestly don't know.
