AI Technical Summary
In biopharmaceutical and chemical experiments, researchers often forget the sample addition process, and existing technologies increase workload or interfere with fluorescence reactions, failing to effectively assist in recording sample addition actions.
The sample addition auxiliary device, which adopts the magnetic control principle, includes a ring magnet, an auxiliary well plate, iron beads, and a sealing cap. The magnet controls the movement of the iron beads between the high and low step mechanisms, and the attraction of the ring magnet achieves automatic marking, eliminating the need for additional memory and identification during the sample addition process.
It reduces the workload of laboratory personnel, improves work efficiency, avoids mislabeling, simplifies sample addition, and is suitable for various well plate types.
