Locking tips securely into place to deliver an airtight seal on every channel, the Thermo Scientific F1-ClipTip will not leak air, loosen or fall off in the middle of their protocols, ruining or contaminating the assay. The interlocking design securely locks tips in place, which increases reproducibility, reduces force required to attach the tips and ensures the best possible accuracy and precision. Available for both single and multichannel pipettes, each tip is clipped securely on the F1-ClipTip pipette using a patented three-interlocking clip design. The pipette and tip form a complete seal to secure the sample volume in each tip for enhanced accuracy and precision.
