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.

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, and wherein each of the one or more calibration features is an aperture formed through an entire thickness of the holder or is an insert of a transparent or substantially transparent material which is placed into a hole in the holder.
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 defining an axis of rotation 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,
- wherein each of the one or more calibration features is an aperture formed through an entire thickness of the holder or is an insert of a transparent or substantially transparent material which is placed into a hole in the holder, and
- wherein at least one of the one or more outer edges includes a cross-sectional shape taken parallel to the axis of rotation, and wherein at least a portion of the cross-sectional shape is not parallel to the axis of rotation.
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;
- a plurality of calibration features, wherein each calibration feature includes a respective outer edge which lies on the side of the calibration feature which is furthest from the centre point, and wherein each outer edge is spaced at different distances from the centre point, and wherein each of the plurality of calibration features is an aperture formed through an entire thickness of the holder or is an insert of a transparent or substantially transparent material which is placed into a hole in the holder;
- and
- wherein each calibration feature includes an inner edge opposite the outer edge, and wherein the inner edge of each calibration feature is spaced the same radial distance from the centre point.
