ABSTRACT:
A method and apparatus for layering a liquid sample onto a support liquid through a narrow filler passage in a neck protruding from the opening in a substantially closed, flexible centrifuge tube by supporting the tube with its liquid support contents in an upright position, attaching a funnel shaped container to the neck of the tube, applying a squeezing force to the flexible tube to reduce its internal volume thereby forcing the liquid contents into the neck thereof to form a meniscus adjacent the opening of the filler passage, adding a sample liquid into the funnel shaped container above the filler opening and in contact with the meniscus of the support liquid, and releasing the squeezing force from the tube allowing it to return to its normal volume thereby drawing the sample into the tube layered on top of the support liquid.
