    Abstract: A sample holder (100) for an apparatus (300) configured to perform an assay at a plurality of sample sites (130) is disclosed, wherein each sample site comprises a concatemer. The sample holder comprises a rotatable body (110), a matrix layer (120) and a liquid layer arranged on the matrix layer. The plurality of samples sites are distributed in the matrix layer in both a lateral direction and a thickness direction of the matrix layer, and the rotatable body is configured to be arranged in the apparatus to be rotatable around an axis (A) while the assay is performed at the plurality of sample sites. A corresponding method (200) and apparatus (300) are also disclosed.

    Abstract: An instrument determines a concentration of bacteria in a plurality of fluid samples, and comprises a housing, a rotatable platform, a plurality of fluid containers, a light source, a sensor, and a motor. The rotatable platform is within the housing. The fluid containers are located on the rotatable platform. Each fluid container holds a corresponding one of the plurality of fluid samples, and has an input window and an output window. The light source provides an input beam for transmission into the input windows of the fluid containers and through the corresponding fluid samples. The input beam creates a forward-scatter signal associated with the concentration of bacteria. The motor rotates the rotatable platform so that the input beam sequentially passes through each fluid sample. A sensor within the housing detects the forward-scatter signal exiting from the output window associated with the fluid sample receiving the input beam.

    Abstract: A method for monitoring consumption or release of a gaseous analyte such as oxygen by a liquid sample under investigation includes providing a cuvette (1) having an elongate narrow tube (12) of a material which is substantially gas impermeable and which is at least partly transparent to measurement excitation radiation and emission radiation along some of the length of the tube. The tube (12) has a cross-sectional area of under 1 mm2. The sample (15) is loaded into the cuvette (1), the sample being in contact with a probe in the tube (12), the probe being sensitive to the gaseous analyte, and the liquid having at least one surface and an associated headspace (16). The cuvette, the sample, and the probe are equilibrated at a target measurement temperature. Excitation radiation is directed at a sampling zone of the tube (12) and which is distal from the headspace (16), while maintaining the cuvette at the measurement temperature. The emitted radiation is measured and analysed to determine consumption or release by the sample of the gaseous analyte.
