Laboratory plastic components—such as test tubes, beakers, and microplate readers—require chemical resistance, precision, and leak-proof seals to ensure accurate experimental results. These components are used in chemical, biological, and medical research, where they come into contact with a wide range of reagents and samples. Traditional welding methods may produce welds that are resistant to chemicals or leak, leading to experimental errors or contamination. DaokeDao plastic laser welding provides stable, leak-proof joints that are resistant to a wide range of chemicals, including acids, bases, and organic solvents. The non-contact process generates no particles or contaminants, ensuring the cleanliness of laboratory components. It achieves high precision, maintaining the dimensional accuracy of components such as microplates and test tubes. The process is compatible with laboratory-grade plastics, including PP, PE, PC, and COC, which are resistant to chemical degradation. Our laser systems support complex designs, adapting to the diverse needs of laboratory equipment. They ensure high yield rates and consistent quality, helping laboratory equipment manufacturers improve product reliability and experimental accuracy.
