A centrifuge device operably configured to simultaneously spin multiple sample tubes at different g-forces during a single centrifugation cycle. The centrifuge device includes a base and a rotatable member disposed within the base and configured as a rotor. The rotatable member includes a plurality of receptacles and a center portion, and wherein each of the receptacles is spaced equally apart from the center portion. The centrifuge also includes a first tube holder selectively inserted within one of the receptacles, wherein the first tube holder includes a first tube therein and a second tube holder selectively inserted within another one of the receptacles, wherein the second tube holder includes a second tube therein. The first tube is operably configured to be spun at a different relative centrifugal force than the second tube.

Provided is a centrifuge. In a centrifuge sample container (40) having a body part (41) and a bottom part (42), the body part (41) has two parallel flat surfaces, and includes an opening (44) having an elliptical shape from above view. The bottom part (42) is formed by a semi-cylindrical part (42a) and quarter spherical parts (42b) connected to the sides of the semi-cylindrical part. A height (H) of the sample container is greater than a length (L.sub.2) in the short axis direction of the opening, and a curvature radius (R.sub.1) of the outer surface of an arc part of the elliptical shape, a curvature radius (R.sub.2) of the outer surface of the semi-cylindrical part, and a curvature radius (R.sub.3) of the outer surface of the quarter spherical parts are equal. A flange part (43) that expands radially outward is formed on the opening (44) of the body part (41).

Provided are methods and apparatuses for controlling a position of a target point on a processing result relative to a focus point of a focusing sensor system for determining properties of the processing result. The method includes the steps of determining an initial focus point of the focusing sensor system, controlling rotation of the cartridge and disc, checking whether the initial focus point of the focusing sensor system corresponds to the target point on the processing result, comparing (x, y) target positions in captured images with the initial focus point of the focusing sensor system, adjusting rotation of the cartridge and disc such that the focus point of the focusing sensor system corresponds to the target point on the processing result, and detecting and examining signals received from the focusing sensor system for determining properties of the processing result.
