Monique, Pipetman is a brand name. It's really annoying sometimes that things just don't always have a standard name that's used for them.
Rockind, are you talking about the pump that you attach a serological pipet to, or the ones that are used for smaller volumes that you just attach a pipet tip to? We have many names for the pump, depending on our mood, since nobody seems to know it's real name...everything from pipet pump, pipet woman (since the smaller ones get called pipetmen, even though it's a brand name), pipet boy, electric pipettor, and occassionally, the bzzzz bzzzz thing (for the sound it makes when using it...so far that's been the most universally useful term when asking who's seen it last). Probably if you just look it up under the general term pipettor, you'll find it.
