Patent number: 11273440Abstract: A separator separates a first from a second phase of a liquid in a tubular container. The separator has a float made of elastic material having a circumferential sealing edge and at least one ballast fastened to the underside of the float. The density of the ballast is greater than the density of the float and the density of the entire separator lies in a value range between the density of the first phase and the density of the second phase of the liquid. In order to securely prevent penetration of parts of the second phase of the liquid into the region above the separator within the tubular container, when the separator moves into the sealing position and is positioned there, the sealing edge of the float is formed at a predetermined distance greater than zero above the center of gravity of the entire separator.Type: GrantFiled: April 25, 2018Date of Patent: March 15, 2022Assignee: SARSTEDT AKTIENGESELLSCHAFT & CO. KGInventors: Mark Weinstock, Christian Wegener, Ulrich Karrenberg

Patent number: 11241686Abstract: A separator for separating a first from a second phase of a liquid in a tubular container has an elastic float with a circular sealing edge for sealing engagement with the inside of the tubular container in a sealing position. At the underside of the float, a ballast is attached. The density of the ballast is greater than the density of the float and the density of the entire separator is in a range between the density of the first phase and the density of the second phase of the liquid. The float has a local constriction and, in the area of the constriction, a membrane.Type: GrantFiled: April 25, 2018Date of Patent: February 8, 2022Assignee: SARSTEDT AKTIENGESELLSCHAFT & CO.KGInventors: Mark Weinstock, Christian Wegener, Ulrich Karrenberg

The density of the ballast is greater than the density of the float and the density of the entire separator lies in a value range between the density of the first phase and the density of the second phase of the liquid. In order to ensure an unrestricted light inflow of the liquid into volume regions of the container lying below the separator in the initial position, the float is designed disk-shaped; and that the ballast is designed in the form of a plurality of fingers extending away from the underside of the disk-shaped float, distributed at its edge.Type: GrantFiled: April 25, 2018Date of Patent: February 8, 2022Assignee: SARSTEDT AKTIENGESELLSCHAFT & CO.
