Multi channel washing machineIt is a key automated equipment in modern immune analysis, cell culture, drug screening and other experiments, widely used in hospital laboratories, biological laboratories and pharmaceutical companies. Its main function is to complete efficient and uniform washing steps in microplate detection processes such as enzyme-linked immunosorbent assay (ELISA), remove unbound reagents, and improve detection accuracy and repeatability. It is crucial to understand the core components and their performance requirements in order to ensure a stable and reliable washing effect.
1、 Multi channel hair washing system
Multi channel hair washing is the most critical component of a washing machine, usually consisting of 8 or 12 independent cleaning channels, corresponding to the rows or columns of a standard microplate. The nozzle design should ensure even distribution of liquid and avoid blockage or leakage. The high-performance hair washing system has good corrosion resistance, can adapt to various buffers and cleaning solutions, and supports automatic height adjustment to adapt to microporous plates of different thicknesses.
2、 Liquid control system
The liquid control system includes pumps, valves, pipelines, and level sensors, which are responsible for accurately controlling the transportation and recovery of cleaning solution. The system needs to have high-precision flow regulation capability to ensure consistent injection volume in each hole, and have anti bubble design to prevent air from entering and affecting washing quality. At the same time, the pipeline material should be made of chemically resistant materials, such as polytetrafluoroethylene (PTFE), to extend its service life.
3、 Waste liquid collection and discharge module
To avoid cross contamination, the washing machine is equipped with a dedicated waste liquid collection container and a liquid level alarm device to prevent overflow. Some models are also equipped with negative pressure suction systems to achieve rapid emptying and improve washing efficiency. The module should be easy to disassemble and clean, maintaining internal cleanliness and hygiene.

4、 Control System and Operating Interface
modernMulti channel washing machineEmbedded control systems are commonly used, combined with LCD touch screens, to provide an intuitive operating interface. Users can customize parameters such as washing frequency, soaking time, and rinsing speed, and support program storage and retrieval functions. The control system also needs to have the ability of fault self diagnosis to facilitate quick troubleshooting.
5、 Micro porous plate positioning and adaptation structure
The washing machine should have good board compatibility and be suitable for various specifications of microporous plates such as 96 hole and 384 hole. The positioning structure shall be accurate and stable to prevent uneven washing or damage to the Flat noodles caused by the displacement of the washing head. Some devices are also equipped with automatic recognition function, which can automatically adjust working parameters according to the board type, improving operational convenience.
In summary, the performance of a multi-channel washing machine depends on the design and manufacturing level of its core components. Only by achieving high standards in hair washing accuracy, liquid control, waste liquid treatment, operation interface, and board type adaptation can efficient, stable, and safe automated board washing operations be truly realized, providing strong technical support for scientific research and clinical testing.
