Dissolution sample transfer device for use in high performance liquid chromatography analysis, comprises needles movable on movement of a delivery head so that their tips are positioned above/in vials

摘要

A dissolution sample transfer device (10) for transferring dissolution samples from dissolution vessels to vials, comprises needles (36) mounted on a movable delivery head (22) and defining a flow passage to a tip, and that are movable on movement of the delivery head so that their tips are positionable immediately above or in vials when vials are received in the receptacles in the rack. A dissolution sample transfer device (10) for transferring dissolution samples from dissolution vessels to vials, comprises needles (36) mounted on a movable delivery head (22) and defining a flow passage to a tip, and that are movable on movement of the delivery head so that their tips are positionable immediately above or in vials when vials are received in the receptacles in the rack. The dissolution sample transfer device also comprises: (i) a transfer module housing (12); (ii) a rack (18) defining several receptacles (20) receivable of vials; and (iii) a conduit unit (e.g. filter members (28) and tubing systems) in connection with the housing for providing several conduits for flow of dissolution samples from dissolution vessels to needles. The movable delivery head is arranged in connection with the housing and movable relative to the rack.
