Vessel dispensing system

A vessel dispensing system for dispensing vessels to an analyzer, the vessel dispensing system comprising:

• a cam disc rotatable about an axis and comprising a guide groove;
• a drum arranged above the cam disc and coupled to the cam disc such as to be rotatable together with the cam disc about the same axis, the drum comprising a plurality of elongated slots arranged along and around the axis, each slot comprising, at one end, an input interface for loading the slot with a plurality of vessels in a stacked manner and, at another end, an output interface for dispensing the vessels from the slot, the output interface comprising a resilient vessel retainer;
• and
• a crank translatable in a linear forwards and backwards direction orthogonal to the cam disc axis between a first, a second and a third position, the crank comprising a drive pin slidable through the guide groove for rotating the cam disc and bringing a slot at a time in a dispensing position upon translation of the crank between the first position and the second position, the crank further comprising an actuator pin translatable with respect to the drive pin for actuating the resilient vessel retainer of the output interface of the slot in the dispensing position upon translation of the crank between the second position and the third position, thereby allowing the vessels to be dispensed from the slot.
