Every experimental paper I've ever read has contained an "Experimental" section, where they provide the details on how they did it. Those sections tend to be general enough, albeit concise.

In some fields, aside from specialized knowledge, good experimental work requires what we call "hands." For instance, handling air sensitive compounds, or anything in a condensed or crystalline state. In my thesis experiment, some of the equipment was hand made, by me.

Sometimes specialized facilities are needed. My doctoral thesis project used roughly 1/2 million dollars of gear, and some of the equipment that I used was obsolete and unavailable by the time I finished.
