Pipette Tips 101 : A Complete Guide to Types, Uses, and How to Choose the Right Tip

Pipette Tips 101: A Complete Guide to Types, Uses, and How to Choose the Right Tip

Pipette tips are one of the most essential consumables used in molecular biology, cell biology, chemistry, and countless laboratory workflows.
Despite being small and inexpensive, they have a major impact on accuracy, reproducibility, and contamination control.

This guide provides a clear overview of tip types, how to choose the right one, and common errors researchers should avoid.

1. What Are Pipette Tips?

Pipette tips are disposable polypropylene attachments used with micropipettes to aspirate and dispense liquids accurately.
Their geometry, elasticity, manufacturing precision, and surface quality all influence pipetting performance.

A pipette is only as accurate as the tip attached to it.

2. Main Types of Pipette Tips

① Standard Tips

General-purpose tips suitable for PCR setup, reagent preparation, serial dilution, and routine workflows.

② Filter Tips

Contain a hydrophobic barrier to prevent aerosol contamination and sample carryover.
Essential for PCR, DNA/RNA handling, viral work, and NGS sample prep.

③ Low-Binding Tips (**Prepare from Japan)

Designed to minimize sample adhesion. Ideal for:

  • DNA / RNA

  • Proteins

  • EVs and nanoparticles

  • Other low-concentration samples

④ Long Tips

Useful for reaching deep-well plates or tall tubes safely.

⑤ Wide-Bore Tips

Prevent shear stress when handling sensitive samples such as cells, viscous solutions, or long DNA fragments.

3. Choosing Tips Based on Volume Range

Pipette Range Tip Size
0.1–10 µL 10 µL
2–20 µL 20 µL
20–200 µL 200 µL
100–1000 µL 1000 µL

Using the wrong size reduces accuracy and increases residual liquid.

4. Why Tip Geometry and Fit Matter

Poor fit leads to:

  • Inconsistent aspiration

  • Leaks

  • Excessive force during mounting

  • Carryover and residual liquid

High-precision molding (like WATSON’s proprietary molds and automated production lines) ensures consistent fit and minimal variability.

5. Recommended Tips by Application

🔬 PCR / DNA / RNA workflows

→ Filter Tips

🧬 Protein analysis / Low-concentration samples

→ Low-Binding Tips

🧫 Cell suspensions

→ Wide-Bore Tips

🧪 General liquid handling

→ Standard Tips

6. Common Pipetting Errors and How to Avoid Them

❌ Poor tip mounting

→ Leads to leaks and inaccurate volume

❌ High residual liquid

→ Caused by surface tension or poor molding

❌ Tips falling off

→ Due to tolerance mismatch

High-quality tips prevent these issues and ensure reliable results.

7. Conclusion: Quality Tips Improve Data Quality

Accurate pipetting begins with choosing the right tip.
A high-quality tip improves:

  • Accuracy

  • Reproducibility

  • Contamination control

  • Workflow efficiency

Investing in better tips is a direct investment in better science.
