Claim:
1. A method of conveying samples, comprising the steps of: dispatching individual elongated items holding samples in succession into a path in a tube system at at least one dispatch station by supplying a constant flow of pressurized air to the tube system and to a by-pass duct that extends around the at least one dispatch station from an upstream to a downstream side without disrupting or boosting the flow of pressurized air during the dispatching of an item, conveying the elongated items holding samples along said path from said at least one dispatch station with said constant flow of pressurized air to at least one receiver station in the a flow direction of the pressurized air along the path, and moving elongated items already underway along said path in the tube system in an uninterrupted manner during said dispatching of individual elongated items into said path.
