Pipetting recommendations
•
Aspirate liquid into the pipette only when the tips are attached. Hold the pipette
vertically when aspirating and dip the tips only 2-3mm into the liquid.
•
Pre-rinse the tips five times before aspiration by filling and emptying the tips.
•
Always control the push button movements with the thumb for consistency.
Allow the liquid, tips and pipette to equilibrate to the ambient temperature before use.
•
When not in use, place the pipette on a bench to avoid transferring body heat
resulting in incorrect dispensing volume
•
Use the correct pipette tips designed for the use with the particular pipette.
•
Select the correct pipetting technique (e.g. reverse, forward pipetting) depending on
the nature of the liquid.
•
Don‘t lay down the pipette with the filled tip, otherwise the liquid can flow into the
pipette and contaminate it.
