Yes of course! Under experience, you can include anything from lab work to volunteer hours, computer skills to retail. As long as it may be applied to the job that you are working at, it should be put under experience.
For example, if you worked at a clothing boutique, and then applied to a job at as a tutor, that really wouldn't benefit your "experience".
However, in your case, lab work consists of several different responsibilities, all of which can be applied to a specific field of study.
