Cuvette for a water analysis instrument

A magnetically-coupled stirring apparatus is provided. The stirring apparatus includes a rotor including at least one rotor magnet, with the rotor being positioned within a chamber. The stirring apparatus further includes an offset stirrer device positioned outside of the chamber. The offset stirrer device includes a shaft including a first end and a second end, with a stirring device axis being offset from a rotor axis, one or more paddle portions extending from the second end, and at least one stirrer magnet affixed to the first end. The at least one rotor magnet magnetically interacts with the at least one stirrer magnet. Rotation of the rotor induces rotation of the offset stirrer device.

A turbidimeter having an arrangement of internal surfaces, optical surfaces, and optical restrictions to the field of view of both the illumination and the detector means to significantly improve the lower detection limit of the turbidimeter by reducing the detected signal due to stray light.

Low detection limit turbidimeter

An optical gasket system for use in a colorimeter or other instrument which utilizes a light beam and a sample cell or chamber for a liquid to be tested. Each gasket is optically clear and is pliable so as to conform to the surface of the sample cell which is in the path of the light beam. The gaskets prevent moisture from condensing on the surface of the sample cell and interfering with the passage of the light beam through the cell.
