A filtration apparatus and method is disclosed, the apparatus including a container tube for holding a sample to be filtered and a filtering vessel inserted therein. The filtering vessel carries a filter over its lower end and includes a chamber portion for receiving the filtrate. The method includes forcibly immersing the filtration vessel into the container tube, limiting the relative axial position therebetween, and subjecting the apparatus to centrifugation. The apparatus and method is useful for filtering dilute, concentrated and particle-laden samples. |
