ABSTRACT:
A transfer unit for transferring a sample from a source vessel to a target vessel. The transfer unit includes a transfer device having a pin tip with a central bore terminating at a bottom wall, an actuating element movably disposed in the pin tip bore, an actuator rod for moving the actuating element and a compensating device connected between the actuating element and the actuator rod. The actuator rod moves the actuating element between a first position adjacent the tip bottom wall and a second position away from the bottom wall. Movement of the actuating element causes a sample in proximity to the pin tip to be alternately collected and released from the pin tip. Such movement also defines a stroke length for the actuator rod, wherein the compensating device compensates for any variations in the actuator rod stroke length. The transfer unit further includes a tip ejector for removing the disposable tips from the transfer device and a tip loading station for applying the tips to the transfer device.
