Abstract: A method for lowering the pressure inside the hood interior of a separator arrangement with a separator with a rotatable drum includes rotating the rotatable drum about a vertical rotation axis. Before processing a product that is to be processed, a liquid is first directed through the drum and the pressure inside the hood interior is lowered, by a device, as a result of rotations of the drum in the manner of a jet pump. After the pressure inside the hood interior has been lowered sufficiently, then the actual processing of the product that is to be processed is performed.

Abstract: Sterilizable separator tubes and methods of utilization of same are presented. Methods include providing a separator tube containing a separator substance that can be polymerized to a desired hardness following sterilization using radical generating radiation. The separator substance is formulated to have a density between that of the average densities of separable fractions derived from a sample fluid such as blood, and to be flowable. Upon centrifugation of a separator tube containing a fluid sample, the separator substance forms a barrier between the fractions. The barrier subsequently hardens to form a solid barrier when triggered by a suitable energy source.
