Abstract
Apparatus for use in dispensing fluid into individual containers is disclosed. The apparatus comprises a dispensing head and a transport mechanism comprising an endless conveyor, the dispensing head being attached to the conveyor, which conveyor provides means for moving the dispensing head in a predetermined path above an array of sample containers. A drive arrangement is provided for the transport mechanism, there being a detector incorporated in the drive arrangement for indicating when the drive arrangement has driven the transport mechanism so that the conveyor has moved the dispensing head a predetermined distance along the predetermined path. Furthermore, there is electronic control circuitry for controlling the time during which the head dispenses into an individual container, the circuitry initiating the drive arrangement, to drive the transport mechanism, after repeated time intervals, and being coupled with the detector to stop the drive arrangement in response to an indication from the detector that the drive arrangement has driven the transport mechanism so that the conveyor has moved the dispensing head the said predetermined distance.
