Abstract

Apparatus for collecting a sample of liquid, such as blood, having a plurality of phases of differing densities. Disclosed is an apparatus for collecting a sample in an enclosed chamber, wherein said apparatus can be used with a separating means which rotates the chamber about either a longitudinal axis of the chamber, or about an axis perpendicular to the longitudinal axis of the chamber and not passing through the chamber. In addition, said apparatus facilitates automated manipulation of the sample by providing formed features for: decreasing the gas permeability of said apparatus; clot activation of a blood sample contained within said apparatus; interconnection of a multiplicity of said apparatus; automated manipulation of said apparatus; protecting markings upon said apparatus; layering the construction of said apparatus; and, encoding of information upon said apparatus in both a tactile and visual manner. Also disclosed is an apparatus for dispensing fluid from said enclosed chamber.
