How a Pipetting System Works

By Thermo Fisher Scientific

Problem: Pipetting is a fundamental activity for a laboratory scientist. Almost every experiment requires small and precise volumes of liquid to be transferred from one container to another. Researchers are often challenged with pipette tips that appear to be seated properly and sealed, but leak air, loosen or fall off in the middle of protocols. This causes inconsistent or unreliable results, and ultimately degrades research results and overall efficiency.

Thermo Scientific F1-ClipTip ^ The Thermo Scientific F1-ClipTip interface is strong enough that users can hang a 2lb weight off the tip and the tips only release when users decide to eject them.Solution: To reduce pipetting variables, a system such as the Thermo Scientific F1-ClipTip pipetting system can help. The Thermo system uses ClipTip interlocking technology to enable researchers to deliver consistent, reproducible pipetting with higher quality results.

With this particular system a light touch ‘clips’ each tip securely on the F1-ClipTip pipette and will only release when ejected regardless of application pressure. The ClipTip technology is based on flexible clips positioned evenly around the upper sealing portion of the tip. During attachment, the pipette tip cone expands the clips, allowing them to pass over a fitting flange and then return to the closed position, and locking the tip into place. The pipette and tip form a complete seal between the tip and the pipette tip cone, securing the sample volume in each tip for enhanced accuracy and precision. Whether lab workers are using a single or multichannel pipette, they will get the exact volume they expect to accelerate discovery.

F1-ClipTip ^When the Thermo Scientific F1-ClipTip pipette tips are on, they are sealed and will not loosen.The F1-ClipTip product offering covers a volume range from 1 μl to 1000 μl and includes variable and fixed volume single channel pipettes as well as multichannel pipettes. Also, a convenient color-coding system makes it easy to identify the correct ClipTip by volume. Each ClipTip tip utilizes low retention technology in the molding process to enable maximum sample recovery and reproducibility. ClipTips are also available with a filter and are certified free of DNA, RNase, DNase, ATP and endotoxin contamination.

A system like the Thermo Scientific F1-ClipTip pipetting system ensures that tips don’t fall off, without requiring excessive force or banging of the tips onto the pipette, and can improve the efficiency of a researcher through improved data integrity.
