How to Choose the Best Liquid Handling Tools for Cell Culture and PCR

– Precision Pipetting Shapes the Quality of Your Research –

In life science research, precision in liquid handling can make or break your experiment.
Especially in delicate protocols like cell culture or PCR, even the slightest pipetting error can drastically affect your results.

This blog will walk you through how to select the right liquid handling tools for such experiments, and how WATSON’s products can support your lab’s workflow.


🧪 Choose Your Pipette Based on the Experiment Type

The purpose of your liquid transfer determines your best tool:

  • Cell Culture: You need a user-friendly pipette that minimizes wrist fatigue and prevents contamination. A smooth eject mechanism and comfortable grip are also important for long hours of work.

  • PCR: Accuracy is everything. A pipette with high dispensing precision is crucial for microliter or even sub-microliter volumes.

For PCR especially, ±1 μL variation can be the difference between success and failure.


🛡️ Filter Tips: A Must for Contamination Control

When you're handling PCR, RNA, or any experiment where aerosol contamination is a concern, filter tips are essential.

Look for:

  • RNase / DNase-free, human DNA-free certification

  • Hydrophobic filter to prevent sample backflow

  • Pre-sterilized and disposable for convenience and safety

🔺 Note: Filter tips are not autoclavable due to the delicate nature of the built-in filter.

Using sterile filter tips ensures both protection of your sample and your pipette from cross-contamination—an essential practice in PCR workflows.


🔀 Single vs Multichannel: Which Should You Choose?

  • Single-channel pipette: Ideal for precise work with small batches.

  • Multichannel pipette: Perfect for 96-well plates or repetitive tasks.

In both PCR and cell culture workflows, multichannel pipettes can drastically cut down on time and pipetting fatigue—especially when processing large numbers of samples or replicates.
