LLG-Low-Retention Pipette tips pipettes, non-sterile
Certified free of DNase, RNase, suitable for microbiology. Guaranteed metal-free.
Sample retention can be a major contributor to pipetting inaccuracy, and siliconization of tips has proved unsatisfactory because of autoclaving and contamination problems. For LLG pipette tips a new polymer, Novelle-Polypropylene has been developed, that produces a "super slick surface" on our new LLG pipette tips, that actually improves with autoclaving and cannot leach from the tip surface. On average, Novelle Polymer and LLG pipette tips reduces the tip retention by near 85% and decreases the standard deviation of the retained volume by more than 75%. 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 LLG pipette tips reduces the binding, thus increasing sample delivery accuracy.
