Continuous centrifuge with air trap for capturing bubbles

Abstract

In a continuous centrifuge, a core end surface component separated from a core body is arranged inside a rotor, an air trap mechanism which automatically captures bubbles inside a sample is formed, and the bubbles are removed by centrifugal separation before the sample is sent to an outer circumferential portion having a high liquid pressure. In addition, when viewed in the axial direction, the core body and an upper rotor cover abut each other, and the core end surface component and a lower rotor cover abut each other, with appropriate pressure by biasing the core end surface component and the core body with a spring. Because a flow path between the rotor core and the rotor covers is maintained in a perfect state and the bubbles in liquid are also removed, the flow path may not be blocked by the bubbles and the centrifugal separation can be stably performed.
