Greiner Bio-One’s new generation of Sapphire pipette tips offer perfect flexibility for laboratory liquid handling. The tips are made of medical polypropylene and benefit from a universal fit on most standard pipettes. They are available in standard, filter, low-retention and filter low-retention versions. By minimizing the adhesion of sample material on the inside of the tip, the low-retention surface ensures maximum precision, even with detergents and other viscous or complex samples. The filter tips reliably prevent the transfer of biological material and aerosols, without this negatively affecting the accuracy of the volume being pipetted.
