Abstract
A device for counting liquid scintillation samples which can count a single sample or several samples simultaneously. A transport system moves samples from a storage section to a counting section. The samples are placed on sample plate holders to assist the transport system in movement of the sample from the storage section to the counting section.

Apparatus for counting liquid scintillation samples in sample plates of a preselected assortment of different multi-well sample plate types, each type having a two dimensional array of sample wells, said apparatus including a counting station comprising at least one detector, each detector provided with two vertically positioned photomultiplier tubes, mounted in two detector assemblies, where at least an upper assembly is movable in a vertical direction, wherein:
- said apparatus is provided with a transportation system for transporting said different multi-well sample plate types belonging to said preselected assortment,
- said transportation system comprises a plurality of different types of sample plate holders, for carrying said different multi-well sample plate types belonging to said preselected assortment,
- said sample plate holders provided with registration means for distinguishing said different types of sample plate holders,
- said different types of sample plate holders being coupled with said transportation system, and
- said different types of sample plate holders provided with equivalent sample plate identification means having a detachable support plate associated with each of said sample plate holders, at least one bar code label attachable on said support plate.
