Abstract: An apparatus for handling sample tubes is presented. The apparatus comprises a sample tube tray, a sample tube individualizer, a first conveyor, a second conveyor, a sample tube buffer, and a sample tube rack inserter. The sample tube tray stores sample tubes in bulk commodity. The sample tube individualizer sequentially unloads single sample tubes from the sample tube tray and sequentially provides the unloaded sample tubes to the first conveyor. The first conveyor conveys the sample tubes to the sample tube buffer. The sample tube buffer buffers the sample tubes provided by the first conveyor and provides buffered sample tubes to the second conveyor with a predeterminable, constant, sample tube rate. The second conveyor conveys the sample tubes to the sample tube rack inserter. The sample tube rack inserter inserts the sample tubes into a sample tube rack.

Abstract: A marker plate embossing system is provided having an improved loading device, and improved chute and hopper systems. The loading device reduces the likelihood of marker plate misfeed. The chute and hopper systems allow the embossing of varying sized embossing plates, while reducing the likelihood of embossed marker plates being delivered in an incorrect stacked-order. A marker plate removal system is also provided for removing embossed marker plates from the hopper system without the marker plates falling out of the stacked-order.
