Cuvette assembly having chambers for containing samples to be evaluated through optical measurement

摘要

The present invention is a cuvette assembly for use in optically measuring at least one characteristic of particles within a plurality of liquid samples. The cuvette assembly comprises a main body having internal walls and external walls, and a plurality of cuvettes within the main body at least partially being defined by the internal walls. Each of the plurality of cuvettes has a liquid-input chamber for receiving a respective one of the plurality of liquid samples, a filter, and an optical chamber for receiving a respective filtered liquid sample caused by passing the respective one of the plurality of liquid samples through the filter. Each of the optical chambers includes an entry window for allowing transmission of an input light beam through the filtered liquid sample and an exit window for transmitting a forward scatter signal caused by the particles within the filtered liquid sample.

主权项

1. A cuvette assembly for use in optically measuring at least one characteristic of particles within a plurality of liquid samples, comprising:
a main body having a unitary upper structure attached thereto, the unitary upper structure defining a plurality of openings, each opening for receiving a respective one of the plurality of liquid samples, each of the plurality of openings leading to an associated liquid-input chamber that is within the main body below the unitary upper structure and in fluidic communication with an associated optical chamber, each optical chamber has an entry window for allowing transmission of an input light beam through the respective liquid sample and an exit window for transmitting a forward scatter signal caused by the particles within the respective liquid sample; and a plurality of individual closure mechanisms located on the unitary upper structure, each of the plurality of closure mechanisms being associated with a respective one of the plurality of openings, each of the plurality of closure mechanisms being movable from an initial opened position for receiving the respective liquid sample to a closed position that inhibits leakage from the associated liquid-input chamber.
