Ernesto Llamas is a Ph.D. student at the Center for Research in Agricultural Genomics in Barcelona, Spain. He uses a micropipette a lot. He also draws comics about his life in science, which he posts at the Facebook page Sketching Science.
Recurring themes in the comics are of scientists being lonely and …micropipettes. You draw what you know. If you’ve ever worked in a biology lab, or you know someone who does, these will hit home.
