An apparatus for the preparation of protein-free filtrates of biological fluids for subsequent amino-acid analysis by paper chromatography is described. The construction allows filtration to be carried out at high pressures, hence increasing the rate of filtration. Contamination by interfering heavy metal ions is avoided by a design in which solutions are exposed only to lucite.
