摘要: The present invention provides methods and apparatus for mixing samples in-line in a microfluidic system, comprising methods of and means for introducing a first fluid sample into a flow-tube at a first end at a first velocity via a first conduit; methods of and means for introducing a second fluid sample into the flow-tube at the first end at a second velocity, the second velocity different from the first velocity, via a second conduit, wherein the first fluid sample and the second fluid sample converge in the flow tube to form an interface; whereby the first fluid sample and the second fluid sample mix at the interface within the flow-tube, wherein fluid flow at the first end of the flow-tube is laminar and fluid flow at a second end of the flow-tube is laminar, and wherein the flow-tube has a constant diameter between the first end and the second end of the flow-tube.
