Why Is Pipetting Accuracy Important?
In clinical and research laboratories, accuracy in measuring liquid volumes is the foundation of every reliable test result. A pipetting error of just 1-2 microliters can cause:
- Inaccurate test results, leading to incorrect diagnoses
- Repeat testing that wastes reagents and time
- Inappropriate patient care, potentially endangering health
- Method validation failures and QC non-conformance
Therefore, choosing quality micropipettes and using proper pipetting techniques are two things that cannot be overlooked.
Understanding Micropipettes
A micropipette is a precision instrument used to aspirate and transfer liquids in micro volumes (1-1000 µL). It operates on the air displacement principle and uses disposable tips for each sample to prevent cross-contamination.

Proper Pipetting Technique (SOP)
Forward Pipetting Steps:
- Attach the tip properly — Press the pipette into the tip with a vertical motion and slight twist. Ensure the tip fits snugly without air gaps
- Pre-wet the tip — Aspirate and dispense the target liquid 2-3 times before actual measurement. This saturates the inner wall of the tip and improves accuracy
- Set the position — Hold the pipette vertically (90° angle) when aspirating
- Immerse correctly — Insert the tip 2-3 mm into the liquid (not too deep)
- Aspirate slowly — Press the plunger to the first stop, immerse the tip, then release the plunger slowly and consistently
- Dispensing — Touch the tip to the wall of the receiving vessel at a 10-45° angle, press the plunger to the first stop, then to the second stop (blow-out)
- Eject the tip — Use the ejector to release the used tip into a waste container
