Finntip filter pipette tips provide protection against contamination for both sample and pipette. The non-sealing filter prevents the transfer of aerosols from tip to pipette and vice versa, ensuring the integrity of any pipetting function. The tips are certified free from DNA, DNase, and RNase and useful in applications such as PCR-based reactions. With extremely low sample retention, the tips are also suitable for pipetting small volumes or valuable compounds. High-molecular weight, virgin polyethylene filters resist aerosol and fluid ingress. The non-sealing nature of the filter allows the safe recovery of a sample after accidental ingress without any loss of integrity. Thermo Electron Corp. 866-984-3766 www.thermo.com/finnpipette
