MBP Gel Cutting Tips by Molecular Biology Products fit a standard 1000 µL pipettor and cut clean plugs from agarose gels with one hand. Choose a 1.1 × 4 mm or 1.1 × 6.5 mm cutting end to match the band width. The polypropylene tips are RNase-free, DNase-free and nonpyrogenic, and a fresh tip for every band helps prevent cross-contamination.
