Sample retention can be a mayor contributor to pipetting inaccuracy, and siliconization of tips has proved unsatisfactory because of autoclaving and contamination problems. AHN Biotechnologie has developed a new polymer, that produces a “super slick surface” on our new Premium-tips, that actually improves with autoclaving and cannot leach from the tip surface. On average, Novelle Polymer and AHN Premium-tips reduces the tip retention by near 85 % and decreases the standard deviation of the retained volume by more than 75 %.
Also liquid handling accuracy and precision are crucial to success in today’s molecular biology laboratories, especially for DNA analysis and protein handling. A significant culprit of pipette inaccuracy is binding of sample. The AHN Premium-tips reduces the binding, thus increasing sample delivery accuracy. Tests demonstrates that AHN Premium-Tips significantly reduces the amount of DNA and protein bound by the tip. Furthermore AHN Premium-Tips offer a marked improvement over the best low retention technologies.
Premium-Line filter tips with very small pore filters are extremely important for applications such as PCR, sequencing, working with infectious and radioactive materials and biological work in which the test results can be affected by contamination. In the filter tips the best available material of polyethylene is included with the smallest pore size. As a result aerosol contamination is reliably prevented. The innovative filters with holds a sample that was accidentally sucked up too far, absolutely safe back. Unlike other filters with self-locking the sample can be easily released again and if necessary disposed.
