Abstract: The present invention relates to a device (100,300) for interfacing a sample transfer device (200) to an analytic or sample preparation device comprising a loading chamber (101), wherein the loading chamber comprises a first port (105) for attaching the device to the analytic device or the sample preparation device and a second port (106) for attaching a sample transfer device, wherein the device (100,300) comprises an insertion opening (104) for inserting a sample kept under atmospheric condition into the loading chamber (101) and a closure element (102) removable from the insertion opening, wherein the insertion opening exhibits a quick-locking mechanism (103) with which the insertion opening can be scaled with the closure element, wherein the device comprises a gate valve (108) attached to the first port (105), wherein the gate valve comprises a pumping port (108a) for evacuating the loading chamber (101) and a venting port (108b) for venting the loading chamber (101).

Abstract: A blood filtering device has a filtration section with filter medium separating raw side and clean side. A first communication path connects raw side and a first variable blood reservoir volume; a second communication path connects raw side and a second variable blood reservoir volume coupled to a receptacle. When varying the first variable blood reservoir volume, blood contained therein flows through first communication path to raw side, plasma/serum passes through the filter medium from raw side to clean side, and residual blood flows from raw side through second communication path into the second variable blood reservoir volume. When varying the second variable blood reservoir volume, blood contained therein flows through second communication path to raw side, plasma/serum passes through the filter medium from raw side to clean side, and residual blood flows from raw side through first communication path into first variable blood reservoir volume.
