摘要

A sample rack is provided to hold receptacles which includes receptacle-receiving pockets, each with a resilient element and a positioning feature for holding receptacles of varying sizes in a predetermined position within the receptacle receiving pocket, and a cover including features for preventing a receptacle from being pulled out of its receptacle-receiving pocket when the transfer mechanism is withdrawn from the receptacle. A method is provided for reading machine-readable labels disposed on the receptacles and associating data read from the label with a rack-receiving location on an apparatus.
