Anyone knows of a cheap(er) source for batteries for Rainin's pipetteman which uses 3.6 V batteries which are of a size of a regular 1.5 V - size D battery? Here in Germany they are selling them for cca. 130 DM (80 US$) EACH. Any ideas how to overcome this problem ? Thanx, Goran e-mail: goran at atax.neur.uni-duesseldorf.de
