Claims15
A microfluidic mixer arranged to mix a first fluid and a second fluid, the microfluidic mixer comprising a mixing chamber and fluid delivery conduits each having a respective fluid delivery port into the mixing chamber,
- the fluid delivery conduits comprising at least one first fluid delivery conduit arranged to deliver the first fluid into the mixing chamber and at least one second fluid delivery conduit arranged to deliver the second fluid into the mixing chamber,
- wherein the mixing chamber has a fluid delivery port portion having a cross-section that is at least substantially circular and the fluid delivery conduits are disposed radially outwards of the delivery port portion and such that the fluid delivery ports form a substantially continuous and substantially complete ring around the fluid delivery port portion,
- and where further the at least one first fluid delivery conduit is arranged so that first fluid delivered by each of the at least one first fluid delivery conduits forms a respective first flow in the mixing chamber and the at least one second fluid delivery conduit is arranged so that second fluid delivered by each of the at least one second fluid delivery conduits forms a respective second flow in the mixing chamber,
- and where the fluid delivery conduits are arranged so that the first and second flows are focussed at a substantially common focus point within the mixing chamber.
A method of mixing a first fluid and a second fluid in a microfluidic manner, the method comprising, delivering a first fluid in at least one first flow and a second fluid in at least one second flow from positions which define a substantially continuous and substantially complete ring of a substantially circular shape towards a substantially common focus point.
A method of manufacturing a microfluidic mixer from a substrate block, the method comprising forming the microfluidic mixer inside the substrate block using selective laser etching.
