Luminometer for automatic analyser

摘要

An instrument for detecting the amount of light emitted from the contents of a receptacle vessel, said instrument comprising:
structure defining a transport path along which a plurality of adjacently-arranged receptacle vessels are moved through the instrument;
a photosensitive device disposed along said transport path and constructed and arranged to detect light emitted from the contents of a receptacle vessel operatively positioned with respect to said photosensitive device; and
a receptacle vessel isolating device positioned adjacent said transport path and constructed and arranged to pivot between: (1) a first position permitting the plurality of adjacently-arranged receptacle vessels to be moved along said transport path; and (2) a second position operatively engaging one of said receptacle vessels disposed on said transport path and operatively positioned with respect to said photosensitive device, said receptacle vessel isolating device being constructed and arranged to substantially prevent light from sources other than said operatively positioned receptacle vessel engaged by said receptacle vessel isolating device from being detected by said photosensitive device, said receptacle vessel isolating device being constructed and arranged to pivotally rotate between said first and second positions and including structure at least partially surrounding a receptacle vessel engaged by said receptacle vessel isolating device when said receptacle vessel isolating device is in said second position.
