Abstract
Abstract A plurality of laterally spaced apart syringes are carried on a rotatable rod, their plungers being fixedly secured in a drive bar so that the plungers are simultaneously displaceable in one position to aspirate a predetermined quantity of sample and in another position to deliver a given quantity of the sample. Drive means are provided for simultaneously displacing the drive bar in the sample delivery direction and horizontally displacing the sample delivery station.
