Abstract
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 necessary without dislodging or disturbing the sample within the apparatus, or the arrangement of the apparatus itself. A sample can be transferred from the apparatus which serves as a preparation zone, to a separate analysis zone. An apparatus is shown of a type utilizing a container and a petter, said petter provided with an upper portion which enables attachment to the container, a lower retainer portion including a peripheral aperture, the non-apertured portion of which enables wedge-fit thereof into the container, and a body portion connecting the upper petter portion and lower retainer portion.
