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.
