Abstract
A method of testing a biological sample, the method comprising: providing a centrifuge sample holder having a camera; arranging a transparent container comprising a fluid test medium in a recess of said centrifuge sample holder, wherein the camera is arranged to image a portion of the container comprising said fluid test medium; arranging said biological sample above and not in contact with said fluid test medium in said container; and with the camera, imaging a mixing of said biological sample with said fluid test medium while centrifuging the sample holder.
Claims16
A method of testing a biological sample, the method comprising:
- providing a centrifuge comprising a rotor comprising one or more arms;
- providing a centrifuge sample holder comprising an axis for hingedly coupling the centrifuge sample holder to an arm of the one or more arms of the rotor, a recess extending in a vertical direction when the centrifuge is not rotating, and a camera directly attached to an external surface of a wall of the centrifuge sample holder surrounding the recess;
- arranging a transparent container comprising a test medium in the recess of said centrifuge sample holder such that the container has a fixed relationship with the camera directly attached to the centrifuge sample holder, wherein the camera is arranged at a location on the external surface of the centrifuge sample holder to image a portion of the container comprising said test medium;
- arranging said biological sample in a location of said container above and not in contact with said test medium in said container in vertical orientation when the centrifuge is not rotating;
- and
- with the camera, imaging a mixing of said biological sample with said test medium while centrifuging the sample holder.
A biological sample centrifugation apparatus, the apparatus comprising:
- a rotor having one or more arms;
- and
- a centrifuge sample holder having a camera directly attached to an external surface of a wall of the centrifuge sample holder surrounding a recess;
- the centrifuge sample holder comprising an axis for hingedly coupling the centrifuge sample holder to an arm of the one or more arms of the rotor, the recess extending in a vertical direction when the centrifuge is not rotating and arranged for receiving a transparent container comprising a test medium, such that the container has a fixed relationship with the camera attached to the centrifuge sample holder, wherein the camera is arranged at a location on the external surface on the centrifuge sample holder to image a portion of the container comprising said test medium when said container is received in said recess;
- the camera being arranged for, while the container is centrifuged, imaging a mixing of said test medium with a biological sample, wherein the biological sample is arranged prior to centrifuging the container, in a location of said container above and not in contact with said test medium in said container.
