If you choose the wrong suction head type, the precision and accuracy of even the best calibrated pipette can be wiped out. Depending on the experiment you're conducting, the wrong type of suction head can also make your pipette a source of contamination, resulting in wasting valuable samples or reagents, or even physically hurting you in the form of repetitive stress injury (RSI).

Select high quality pipette tips for precision and accuracy

When considering which type of suction head to choose, the first considerations that come to mind are precision and accuracy.

If the suction head does not fit your specific pipette, it may affect the accuracy of the pipette. If the seal between the pipette barrel and the suction head is poor, the inhaled air may escape, making it impossible to draw out the correct volume of liquid. Therefore, the final volume assigned is not infallible. Choosing the right suction for your pipette can be a tricky business.
