Description

Hand-held single-hole bead divider Technical Field The utility model relates to the technical field of bead separators, in particular to a handheld single-hole bead separator. Background Microbeads of different materials are widely used in the biological field, for example, in DNA extraction, steel balls are usually added for grinding in order to achieve efficient breaking of samples. In the prior art, based on the high-throughput experiment requirement, a steel ball separator which is adaptive to a 96-hole reaction plate has been developed, and can realize single operation to accurately distribute one steel ball into 96 holes. However, in practical application scenes, there is a wide demand for adding microbeads by taking centrifuge tubes, micro-reaction tubes and special-shaped vessels as containers, and the containers only have one adding hole, so that the existing 96 Kong Fenzhu devices are obviously not applicable.
