AHN ULR-Filter Tips, Ultra Low Retention Filter Tips

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, Novelle-Polypropylene, that produces a “super slick surface” on our new ULR-tips, that actually improves with autoclaving and cannot leach from the tip surface. On average, Novelle Polymer and AHN ULR-tips reduces the tip retention by near 85 % and decreases the standard deviation of the retained volume by more than 75 %.

AHN ULR-Filter Tips Molecular Biology Applications

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 ULR-tips reduces the binding, thus increasing sample delivery accuracy. Tests demonstrates that AHN ULR-Tips significantly reduces the amount of DNA and protein bound by the tip. Furthermore AHN ULR-Filter Tips offer a marked improvement over the best low retention technologies.
