Micropipette, Variable Volume
Solution preparation relies upon the precise measurement of volumes to obtain the exact concentrations required. Therefore, the choice of micropipette that is used can determine not only the accuracy - but also the reproducibility of your experiments.
At Ossila, we offer a selected range of micropipettes spanning from 0.5 μl all the way up to 10 ml. Each micropipette comes pre-calibrated and tested, to ensure accuracy and reproducibility. Additionally, we have prepared a handy guide on how to properly use your micropipette to get the best results possible.

How to Operate a Micropipette
Correct operation of a micropipette will allow for the most accurate and reproducible measuring and dispensing of solutions. Incorrect operation of a micropipette can cause significant decreases in both the accuracy and reproducibility of the volume of solution being withdrawn or dispensed. Below is a visual guide on how to correctly use a micropipette to get the highest accuracy and longest lifetime out of your equipment:
- When withdrawing solution, do not fully insert the tip. You should aim to have it around 1 cm into the solution to avoid withdrawing close from the surface and taking in air, and avoiding any contact between the micropipette and the solution.
- When withdrawing viscous solutions, the plunger should be released very slowly to ensure that no air bubbles form within the tip (as this will give you a lower volume than indicated).
- Never hold your micropipette with the tip facing upwards while you have solution in the tip. This may cause the solution to run back into the piston mechanism, which will damage and contaminate it.
- When dispensing small volumes, you may need to either dispense directly into the solution by immersing the tip or by dispensing onto the side of the vial. The tip should be replaced after each dispense to avoid cross contamination.
- If a micropipette is set to a volume outside of its stated operational range, the micropipette should be recalibrated to ensure that you are still getting the correct volumes.
- If the micropipette is dropped, this may result in the need to recalibrate it.
For storage of your micropipettes, we recommend using a stand that sets them vertically, allowing you to hold liquid within the tip without it running back into the tip cone. This reduces the chance of contamination, and increases the lifetime and accuracy of your equipment. Ossila offers a carousel stand with 9 individual slots, allowing you to store multiple micropipettes with easy access to each.
