  • Patent number: 5255585
    Abstract: A vacuum system for removal of debris in the form of shavings, particles, or the like has been developed for use inside of a cryostat to evacuate and collect such material as it is generated during specimen preparation using a microtome, also inside of the cryostat. The system includes a vacuum assembly unit containing a vacuum collection nozzle having a suction duct. The cold assembly unit is moveably positioned adjacent to the microtome knife so that debris is suctioned away and removed concurrent with or immediately after its production during cryotomy, and is captured in a cold primary filter. The frozen debris does not melt, but remains rigid while it freeze-dries and is trapped on the filter as cold air flows over and through it, thereby maintaining the collected waste material in a very porous state.

  • Patent number: 4276253
    Abstract: A method for labelling a histological specimen, wherein such specimen is embedded in a paraffin block along with an integral set of supported elongated elements identifying such specimen for subsequent sectioning on a microtome. The identification elements are sectioned concurrently with the specimen, so as to form an integral part of the section.

  • Patent number: 4269139
    Abstract: A method of transferring a substance adhering to the surface of a substrate to a receiving surface of a backing element which includes locating the substrate surface in juxtaposition with the receiving surface, supplying a transfer medium on the receiving surface in sufficient quantity to encapsulate the substance, joining the transfer medium on the backing element with a substance so as to encapsulate the substance within the transfer medium and removing the substrate to expose the encapsulated substance.

  • Patent number: 4065973
    Abstract: A sampler is provided having a liquid sampling probe. A drive mechanism for the probe includes a screw element and a nut element threaded thereon, one of which elements is axially fixed and driven to axially raise and lower the other element which supports the probe. In one axial position of the element supporting the probe, the last-mentioned element is moved between first and second angular positions thereof.

  • Patent number: 4043678
    Abstract: A multichamber cuvette for maintaining in independent and separate condition at least two reactants, one of which may be a sample, until such time that it is desired to mix them for reaction with each other for photometric analysis in the cuvette. At least one of the chambers has a pair of optical quality windows aligned with one another for analysis of the then liquid contents extending between the windows. The cuvette body is of upright construction, defining at least two such chambers laterally of one another, open at the top for filling separately or simultaneously, and interconnected adjacent their lower extremities by a passageway of inverted U shape. The passageway is of an effective height exceeding the highest filling level of each chamber by a distance at least as great as any capillary rise in the passageway beyond such level of the particular liquid in that chamber.

  • Patent number: 3960020
    Abstract: An aspirating probe which has a travel from a lower position in which it is immersed in a liquid in a receptacle to an upper position in which it clears the receptacle, carrying with it in its movement to the upper position a washing device to wash the interior and exterior thereof when in the last-mentioned position.
