One of the most common mistakes I see with pipette guns is not using the correct pipette tip for the volume being measured. Using tips that don’t fit or are incompatible can lead to inaccurate measurements and wasted samples. Always double-check that you have chosen the right tips for your pipette model. Another frequent error is failing to pre-rinse the pipette tips. This step ensures better accuracy, especially when dealing with viscous solutions. Just a single drop left inside can throw off your results. I also notice many users apply excessive force when they’re pressing down the plunger, thinking it will create a better seal. In reality, this can damage the pipette and lead to inconsistent results. Use gentle, smooth motions to expel and draw liquid. It’s essential to hold the pipette vertically while aspirating and dispensing. Tilting can result in air bubbles or incorrect volumes. Lastly, ignore the expiration dates on pipette tips at your own peril; they can degrade over time and affect your experiments. Staying vigilant about these points can make a big difference in your pipetting accuracy.

Pipette-aides or pipettors are suction devices that are used to either suck liquids into or expel liquids out of pipettes.
