5419870 Antibody testing system May 30, 1995
A device for performance of ligand-receptor assay methods for determining the presence of a liquid. The preferred ligand-receptor pair are antigen-antibody pairs. The device has a membrane having the receptor physically bound to its surface. The membrane is disposed at the top of a b
5334538 Gold sol immunoassay system and device August 2, 1994
A new apparatus and method for immunoassays. A gold sol bead is held in a funnel member. First antibodies are associated with the gold sol bead. When the sample contacts the gold sol it dissolves the bead. A second antibody is impregnated on an immunosorbent surface. When the dissolved
5137691 Antibody testing system with removable air gap August 11, 1992
A device for performance of ligand-receptor assay methods for determining the presence of a ligand. The preferred ligand-receptor pair are antigen-antibody pairs. The device has a membrane having the receptor physically bound to its surface. A closable gap exists between the membrane
5132232 Method and apparatus for preparation of liquids for examination July 21, 1992
Method and apparatus for collecting liquid analytical samples for examination, particularly whole urine and blood samples, and reproducibly separating them into two or more fractions. A sample is disposed within such an apparatus, then staining with dye or reacting with reagent as ne
5084241 Apparatus including a sample petter tube for obtaining reproducible liquid samples of small volu January 28, 1992
The disclosure teaches a pipette or petter tube and a system using the pipette to obtain reproducible liquid samples of known small volume. The pipette has an elongate body with one end adapted to be removably engaged by an aspiration device and the other end which is closed is adapted t
4797260 Antibody testing system January 10, 1989
A compound is bound to a membrane which is reactive to a component in a fluid sample which is being tested. Under the membrane a porous support is added. The fluid sample suspected of containing a specific component is drawn over the membrane and into the porous support by a piston and
4735905 Specimen-gathering apparatus and method April 5, 1988
A specimen gathering method and apparatus having a piston operated ejectable scoop member. Preferably, the specimen gathering device inserts into a container and releasably seals the container. The apparatus is useful for gathering and transporting stool and other biological specimen
4299441 Transparent laboratory slide for examination of liquid specimens November 10, 1981
An improved transparent slide, and method of manufacture, the slide having a plurality of covered chambers defined between generally parallel and uniformly spaced sidewalls integral to the slide and having a channeled configuration for inducing a liquid specimen into the chambers, wherei
4022576 Method and apparatus for preparation of liquids containing suspended material for examination May 10, 1977
Method and apparatus for preparing a sample of liquid containing suspended material. The apparatus includes an elongated container with an open end, the internal cross section of the container being tapered to a smaller area near the closed end, and an elongated tube having, in one prefe
4020006 Fluid containing dispersed particles simulating leukocytes and method for producing same April 26, 1977
Microspores derived from flowering plants are dispersed in fluids to simulate leukocytes. Reconstituted body fluids utilized as standards in clinical examination of fluids such as urine contain a known quantity of microspores to simulate leukocytes when examined under a high power field.
