Clean Laser Welding for Medical PCR Reaction Tubes

Date：2026-03-20 14:45 Source：daokedao Browse：3

PCR reaction tubes are used in genetic testing and molecular diagnostics, requiring ultra-clean, leak-proof seals to prevent sample contamination and ensure accurate test results. These tubes are made of medical-grade plastics like PP and COC, demanding a particle-free assembly process. Traditional welding methods generate particles that can contaminate PCR samples, leading to false results. DaokeDao plastic laser welding produces no debris or contaminants, ensuring the ultra-clean environment required for PCR testing. The non-contact process forms a hermetic seal (helium leak rate ≤1×10⁻⁹ mbar·L/s), preventing sample leakage and cross-contamination. It maintains the tube’s dimensional accuracy (tolerance ≤±0.02mm), ensuring consistent sample volume. Our systems are cleanroom-compatible (ISO 7), supporting high-volume production (up to 180 units/hour) with consistent quality. By ensuring PCR tube reliability, DaokeDao laser welding helps diagnostic laboratories improve test accuracy and comply with regulatory requirements.
