功能

• Researchers who perform PCR on a daily basis are always on the hunt for the best thermal cyclers, the best master mixes, the best PCR enzymes, and more. Similarly, the choice of PCR consumables between the PCR cycler and the precious sample is an important factor.
• Using different consumables can cause significant differences in the accuracy and reproducibility of results. Variations in tube thickness and temperature, material stability, and various other factors have a direct and significant impact on the experiment itself and the results.
• All Eppendorf consumables are made from high purity virgin polypropylene (PP).
• Dyes used in consumables do not contain organic substances or heavy metals.
• PCR clean products are guaranteed to be free of human DNA, DNase, RNase and PCR inhibitors *1.

• Made of thin wall type polypropylene. Since the wall thickness is constant and the surface irregularity is small, heat is efficiently and uniformly transferred to the sample.
• The hinged lid has a contamination prevention shield.
• The special hinge keeps the lid angle constant.
• The writing space on the tube and lid is frosted.
• Ideal for thermal cyclers that use blocks for all 0.2 mL tubes.
• Prevention of contamination is an important issue in forensic DNA analysis. In order to minimize contamination risk, the forensic field has established strict internal regulations. ISO 18385 sets out requirements for manufacturers of products used in forensic DNA analysis. Eppendorf Forensic DNA grade products are manufactured to meet the high level requirements of this standard.
• High quality manufacturing
• Forensic DNA Grade products are consumables used for DNA purification, sample preparation, PCR setup and sample storage. The following high quality standards for Eppendorf's manufacturing processes are the foundation for meeting the strict requirements of ISO 18385.
• Highly automated manufacturing facilities to minimize direct contact between workers and products
• Strict cleaning procedures and protocols to minimize contamination risk
• Positive pressure facilities to prevent dust intrusion
• Process controls
• The manufacturing area is strictly monitored to ensure clean conditions at all times. Eppendorf operates an effective quality assurance system to meet the standards and guarantees required of manufacturers such as ISO 13485. In addition, additional controls have been added to meet specific requirements for Forensic DNA Grade consumables. For example, each surface of the manufacturing facility is monitored for the presence of human DNA, and multiple spot checks are performed on each batch during the manufacturing cycle to ensure uniform quality and purity.
• Restricted access
• Access to the manufacturing area of Forensic DNA Grade consumables is strictly restricted and controlled. Worker training and compliance with work wear regulations are mandatory.
• Packaging matters
• Eppendorf's comprehensive approach takes into account not only manufacturing and application content, but also product handling in the lab. Of course this includes packages. For products used in forensic science, the packaging is designed to support the features of the product due to handling that is not prone to contamination or misalignment. That is, the packaging of the Eppendorf Forensic DNA Grade product provides special attention to the following points:
• Clearly labeled packaging as well as product boxes prevents misplacement
• The number of consumables per package is adjusted for each product: EppendorfForensic DNA Grade Consumables are packaged individually or as a number of consumables per package according to workflow
• Even if all consumables are not used at once, resealable packaging is used to prevent contamination.
