Make sure to always draw up solutions out of a clean beaker, rather than the stock supply. This prevents any possibilities for contamination.
Air bubbles can cause your measurement readings to become less accurate.
First, depress the plunger button to the second full stop position. Next, immerse the tip of the pipette into the desired liquid and release the plunger button in a smooth motion. This will draw up the liquid into the pipette’s receiving vessel.
This will force the liquid out of the pipette while retaining any air bubbles that could impact the measurement.
Typically, these transported volumes are added to other liquids during experiments, production, or medical tests.
Accuracy is crucial in most laboratory settings, so pipettes are a good choice for scientists and researchers to use.
First, depress the pipette plunger and immerse the tip into the desired liquid. Be sure to keep the pipette in a vertical position, then release the plunger.
Following these instructions will give you an exact measurement of the liquid you’re trying to move.
You may also wipe down the exterior of the pipette with rubbing alcohol.
Follow all instructions for disassembly from the pipette manufacturer.
Make sure that you allow the pipette to fully air dry before you begin using it again.

Using alcohol to cleanse protein particles will set the proteins and make them impossible to remove later. This could also end up affecting your measuring accuracy and contaminating future liquids.
It may take several hours for a pipette to air dry completely.
