Electronic Pipetting –Time to Rise to The Challenge

Examples are easy to name: An ELISA with foaming BSA solution, DNA extraction with liquids dripping out of the tip, or the preparation of glycerol stocks with liquid sticking inside the pipette tip. For the accurate transfer of challenging liquids, a clear recommendation exists: Use a positive displacement system like the Multipette®/Repeater® . You do not have one at hand? Then you are probably using an air-cushion system: the pipette. Why not using the electronic one?

Electronic pipettes are more robust than you would think and offer a bunch of advantages in terms of precision (repeatability), ergonomics, or mode variety. So far, so good. But why choose the electronic pipette for challenging liquids? Because it offers convenience. Let’s check this out along with the example of transferring a foaming liquid.

Of course, there exist more challenging liquids than this one. The overview below outlines how to deal with the other ones. For more detailed information, please refer to “Pipetting Challenging Liquids.”
