  • Patent number: 7758816
    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.

  • Publication number: 20080070820
    Abstract: Cleaning solutions and related methods for cleaning and removing stains and residues from items and surfaces such as laboratory equipment and surfaces uses cleaning solutions containing from about 25 wt % to about 99 wt % of a liquid sulfoxide and from about 1 wt % to about 75 wt % of a base-water solution. A variety of bases can be used in the base-water solution so long as the base-water solution has a pH of at least about 8. The cleaning solutions are particularly fast and effective in cleaning stains caused by biological staining reagents and solutions. A preferred embodiment of the cleaning solution contains between about 80 wt % liquid sulfoxide, such as dimethyl sulfoxide (DMSO), and between about 10 wt % and about 20 wt % base-water solution, such as a 4.5% potassium hydroxide-water solution.
