    Abstract: Dissolution sample transfer device for transferring dissolution samples from dissolution vessels to vials including a transfer module housing, a rack defining receptacles receivable of vials, a delivery head arranged in connection with the housing and movable relative to the rack, needles mounted on the delivery head and defining a flow passage to a tip thereof, and a conduit system arranged in connection with the housing for providing conduits for flow of dissolution samples from dissolution vessels to the needles. The needles are movable upon movement of the delivery head to position the tips of the needles to condition filters and wash sample lines or immediately above or in vials when received in the receptacles in the rack. It is possible to automatically transfer the dissolution samples from dissolution vessels to vials which can be handled by a sample arm of an analysis device, e.g., grasped directly from the rack.
