Coaxial 96-channel washing head

A coaxial 96-channel washing head is characterized in that 96 thin tubes are embedded in 96 thick tubes respectively to form coaxial tubes which are uniformly inlaid on two layers of flat plates, one more layer of flat plate is added on the flat plates, a cavity is reserved between every two flat plates, a first cavity is used for injecting a liquid into the thin tubes, and the a second cavity is used for sucking the liquid. The washing head can be used for injecting and sucking the liquid, so that the coaxial 96-channel washing head has both functions of plate washing and liquid transferring, can inject the liquid into and suck the liquid from a standard 96-well microwell plate or 96-well ELISA (enzyme linked immunosorbent assay) plate for one time, and can transfer liquid from the standard 96-well microwell plate and a deep-well plate.
