Abstract: The present invention is a pipette-filtration assembly having a main body defining a first channel, a second channel, a first valve, and a second valve. The first valve is associated with the first channel and permits flow in a first direction while substantially hindering flow in a second direction. The second valve is associated with the second channel and permits flow in the second direction while substantially hindering flow in the first direction. At least one filter is used to filter a fluid sample as the fluid sample flows in the first direction and/or the second direction. The pipette-filtration assembly is preferably disposable and includes one or two stages of integral filtration, primarily for use with an air-displacement pipetting or transfer system.

Abstract: An optical measurement instrument is an integrated instrument that includes an optical cavity with a light source, a sample cuvette, and an optical sensor. The light source and sensor are on a bench that is on a translational or rotational mechanical platform such that optical beam can be moved to multiple sample containers. The instrument can be used for taking measurements of organism concentration in multiple samples as a production tool for microbiology. Preferably, the instrument holds multiple, individually-loaded, independent fluid samples and determines bacteria concentration via a forward-scattering signal. The instrument can incorporate onboard incubation to promote bacterial growth in the samples during the test. In another aspect, the instrument can be a part of a network for medical diagnostic testing data where data is stored in a manner that is inherently untainted by patient identifiable information.

Abstract: 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.
