Title: SEPARATION BODY
Abstract:
The invention relates to a separation body (100) for separating a first phase of a liquid from a second phase in a tubular container. The separation body has a float (110) made of elastic material having a circumferential sealing edge (112) and at least one ballast body (120) fastened to the underside of the float. The density of the ballast body is greater than the density of the float, and the density of the entire separation body lies in a range of values between the density of the first phase and the density of the second phase of the liquid. In order to ensure an easy inflow of the liquid in the initial position even in volume regions of the container lying below the separation body, according to the invention, the float is disk-shaped, and the ballast body is designed in the form of a plurality of fingers (124), which extend away from the underside of the disk-shaped float, distributed at the edge thereof.
