Abstract
A cytocentrifuge sample chamber includes a sample receiving well to receive and hold a sample to be centrifuged and a sedimentation chamber adjacent a microscope slide upon which cells and/or other sediment material in the sample is to be deposited. A passage, such as a spillway, connects the sample receiving well and the sedimentation chamber, so that sample flows from the sample well under the influence of centrifugal force as centifugation begins into the sedimentation chamber where the sample is forced by centrifugal force against the microscope slide leaving a vacant space at the inner end of the sedimentation chamber. Sedimentation of the sample takes place against the microscope slide. When centrifugation ends, the liquid components of the sample flow back into the vacant space in the sedimentation chamber and can be removed from the vacant space at the inner end of the sedimentation chamber through a removal chamber. This avoids contamination of equipment and users and allows a secondary centrifugation to take place.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
