ABSTRACT:
In automatic sampling arrangements for supplying liquid samples to analytical instruments, the samples are placed in open bottles in a circular ring in a turntable. The turntable is driven in rotation by a drive assembly under a sampling mechanism. To increase the storage capacity of the turntable, in accordance with the invention, a second ring of bottles is provided at a different radius to the first ring. The circumference of the turntable is provided with cut-outs with which the driving assembly engages. The driving assembly adopts one of two positions depending on the state of engagement with the cut-outs. The sampling mechanism is coupled to the driving assembly such that it adopts one of two positions in synchronism with the driving assembly positions with the first and second positions of the sampling mechanism lying on one or the other of the circular rings.
