If the tip does not load correctly onto a Thermo Scientific KingFisher magnetic head, we recommend that you try manually flexing the tips both lengthwise and widthwise to level the tip comb. A video of flexing the tip comb can be found here: https://www.thermofisher.com/us/en/home/life-science/dna-rna-purification-analysis/automated-purification-extraction/kingfisher-systems/resources.html. The video is under "KingFisher Flex" and titled "How to install the magnet head and check the tip comb." Flexing of the tip comb is demonstrated at timepoint 1:35. If that does not work, try a different box or lot of tips. This applies to all KingFisher instruments.
