Take three giant steps to finer results. Fisher is showing all three at the Pittsburgh Conference — and more. More accurate titrations. Greater automation than ever, too. It's our unique new titration "supercontrol." Shown below in the multi-sample Fisher Titralyzer® II. Its official name is Titrate Demand Module and it automatically varies titrant delivery rate for optimal results. The big news is that it's based entirely on the chemistry of each sample. Totally independent of all other experimental variables, this endpoint-seeking module (patent pending) actually determines your endpoint for you — whatever the sample. Ideal for automating your difficult tests. CIRCLE 241 ON READER SERVICE CARD
