A rapid and highly efficient ultrafiltration apparatus has been devised from readily available laboratory materials costing less than $5. Employing a fritted glass tube to support an evacuated dialysis bag, it accommodates as little as 1 milliliter and is ideally suited to dialysis of small volumes and concentration of macromolecules for chromatography and electrophoresis.
