Abstract: A sample holder for use in a centrifuge, the sample holder being generally planar and comprising: an aperture or recess for releasably retaining a sample storage member including a sample chamber adapted to contain a volume of liquid; a centre point around which the holder will rotate during use; and one or more calibration features, wherein the calibration feature(s) comprise one or more outer edges, which lie on the side of the or each calibration feature which is furthest from the centre point, and the one or more outer edges comprise a series of radially spaced-apart outer edge portions or positions which are spaced at different distances from the centre point as a function of angular position around the centre point.

Abstract: A cuvette comprising: a main body having a sample chamber formed therein, the sample chamber communicating with the exterior of the cuvette by an opening formed in the exterior of the main body, wherein the sample chamber comprises a first sample chamber and a second sample chamber, the first sample chamber being in fluid communication with the opening, and the second sample chamber having a first end which is in fluid communication with the first sample chamber, and a second, closed end, the second sample chamber being in fluid communication with the exterior of the cuvette only through the first chamber, the first chamber having a width which is greater than that of the second chamber, and further wherein the greatest width of the opening is greater than or equal to the greatest width of the first sample chamber, the greatest width of the first sample chamber is greater than or equal to the greatest width of the second sample chamber, and the width of the sample chamber, passing from the opening to the clos

Abstract: A flexible walled bag, tank (1), or flexitank, for shipping fluids, in particular liquids, disposed within an outer container (12) confines, and supportable by a container floor, side walls and end structures, an upper tank surface being constrained, loaded or biassed, by external restraints, such as depending local spaced intrusions or baffles (22) extending from one side towards the other.
