Quality Requirements For PCR Tubes
PCR tubes are an essential component of molecular biology laboratories, and their quality is critical to obtaining accurate and reliable results. What factors may affect the performance of the
PCR storage vial?
(1) Material purity: PCR tubes should be made of non-polluting, high-quality, pure materials. Impurities present in PCR tubes can interfere with PCR reactions and cause erroneous results. PCR tubes should be made of materials such as virgin polypropylene or polypropylene carbonate that are free of RNase, DNase, and PCR inhibitors.
(2) Manufacturing precision: PCR tubes should be manufactured with high precision to ensure uniformity in size, shape, and thickness. Tubes should have a consistent wall thickness for uniform and efficient heat transfer during PCR cycling. Inconsistent wall thickness can lead to uneven temperature distribution and affect PCR performance.
(3) Tight seal: PCR tubes should be tightly sealed to prevent evaporation, contamination, and loss of PCR samples during PCR cycling. Tubes should have reliable caps or caps that provide a tight seal even at high temperatures during PCR cycling.
(4) Heat resistance: PCR tubes should be able to withstand high temperatures generated during PCR cycling without warping, melting, or deformation. They should be able to withstand repeated heating and cooling cycles without compromising their structural integrity or performance.
(5) RNase- and DNase-free: PCR tubes should be certified RNase- and DNase-free to prevent PCR samples from being contaminated by these enzymes that can degrade nucleic acids and affect PCR results. PCR tubes should be thoroughly tested and certified free of RNase and DNase contamination.
(6) PCR compatibility: PCR tubes should be compatible with various PCR instruments and thermal cyclers commonly used in molecular biology laboratories. They should fit securely in the blocks of the PCR instrument and their dimensions (e.g. height and diameter) should conform to the specifications of the instrument.
(7) Quality control and certification: PCR tubes should undergo strict quality control measures during the manufacturing process and be certified to meet quality standards such as ISO 9001 and ISO 13485. Certified PCR tubes ensure consistent performance and reliability of your PCR reactions.
(8) Packaging and labeling: PCR tubes should be packaged in such a way as to prevent contamination, damage, and moisture. The packaging should clearly indicate the batch number, expiry date, product specifications, and other relevant information to facilitate identification and traceability.
(9) Sterility: PCR tubes should be sterile to prevent contamination of the PCR reaction by unwanted microorganisms. Sterility should be confirmed by appropriate methods, such as gamma irradiation or autoclaving, and stated on the product packaging.
