Abstract
Apparatus and method for the automated synthesis of DNA segments utilizing multiple reaction columns, all of which are open at the inlet end to the atmosphere of a reaction chamber. A movable reagent supply line outlet is positioned adjacent to the column inlet end to apply reagent to each of the columns according to an input sequence of delivery. The delivery sequence is under processor control. Reagents are removed from all columns simultaneously through the application of vacuum at the outlet end of each column. The device enables the parallel synthesis of large numbers of different oligonucleotide sequences of different lengths.
