It depends on the work being done in the lab. I have a lab here at work that I process printing plates in, and we don't have any solvents at all. Biology labs have some solvents--they all have at least one kind of alcohol, and the other solvents depend, once again, on the work the lab does. A fuels lab will have many flammable solvents because the things they develop are solvents in their own right.
Two examples are: acetone and paper.
Methanol & ethanol
Paper and cloth.

That would be carbon. The definition of an organic molecule or compound is one that contains carbon. Exceptions are for carbon dioxide, carbon monoxide, and a few other carbon molecules by historic convention.
