Streamline daily pipetting. Thermo Scientific™ F1-ClipTip™ Fixed Volume Single Channel Pipettes feature innovative ClipTip interlocking technology which ensures a complete seal on every channel with minimal tip attachment and ejection force. Achieve newfound confidence knowing that once attached, your tips are locked firmly in place, and will not loosen or fall off regardless of application pressure. The innovative three interlocking clip design ensures the tip is held securely on the F1-ClipTip pipette until — and only until — it is released.
