Abstract
Abstract A DISTRIBUTOR FOR LIQUIDS INCLUDES AT LEAST A PAIR OF SMALL NONWETTING TUBES PLACED IN ALIGNED RELATIONSHIP. THE TUBES ARE SPACED APART ONLY A SMALL DISTANCE SO THAT UNDER CERTAIN CONDITIONS THE LIQUID WILL BRIDGE THE GAP BETWEEN EFFECTING A TOTAL TRANSFER OF A LIQUID DROP FROM ONE TO ANOTHER. A FIRST TUBE CAN BE SELECTIVELY ALIGNED WITH ANY OF A SERIES OF SECOND TUBES SO THAT SAMPLES OF LIQUID FROM A SINGLE SOURCE CAN BE ROUTED TO ANY ONE OF A PLURALITY OF ANALYZERS. ALSO THE SAMPLES MAY BE WITHDRAWN FROM PLURALITY OF SOURCES. SEVERAL ARRANGEMENTS FOR MEASURING DOSES ARE ALSO DISCLOSED.
