How to Choose Pipette Tips for Your Lab: Filtered vs. Non-Filtered, Low Retention vs. Standard

Pipette tips are the most frequently used consumable in any laboratory. Choosing the right tip not only ensures accurate and reproducible results but also protects your pipette and samples from contamination.

With so many options available—filtered, non-filtered, low retention, standard, conductive, automation-compatible—how do you know which one is right for your application?

This guide will help you understand the differences and make an informed decision.

🔬 1. Filtered vs. Non-Filtered Tips

✅ Filtered Tips

Filtered tips contain a built-in aerosol barrier (usually made of polyethylene or polypropylene) that prevents aerosols, liquids, and contaminants from entering the pipette shaft.

When to use filtered tips:

• PCR / qPCR / Molecular Biology – Prevents cross-contamination of nucleic acids
• Radioactive or toxic samples – Protects the user and the pipette
• Infectious or pathogenic samples – Adds an extra layer of safety
• Precious or limited samples – Avoids sample loss due to contamination

Advantages:

• Prevents carryover contamination
• Protects the pipette from corrosion and damage
• Ideal for sensitive applications

✅ Non-Filtered Tips

Non-filtered tips are the standard choice for everyday liquid handling where contamination risk is minimal.

When to use non-filtered tips:

• Routine buffer or reagent dispensing
• General laboratory work
• Applications where cost is a primary concern

Advantages:

• More economical
• Suitable for most general-purpose tasks

🧪 2. Low Retention vs. Standard Tips

✅ Low Retention Tips

Low retention tips are treated with a hydrophobic surface coating that minimizes liquid adhesion to the tip wall. This is especially important when working with viscous samples or expensive reagents.

When to use low retention tips:

• Viscous samples – Glycerol, oils, detergents
• Precious reagents – Enzymes, antibodies, DNA/RNA
• Small volume pipetting (<10μL) – Improves accuracy
• Proteomics / Genomics – Maximizes sample recovery

Advantages:

• Reduces sample residue
• Improves accuracy and precision
• Ideal for high-value samples

✅ Standard Tips

Standard tips have no surface treatment and are suitable for most aqueous solutions.

When to use standard tips:

• Water, buffers, salts
• High-volume dispensing
• General lab use

Advantages:

• Most economical
• Suitable for >90% of lab applications

⚙️ 3. Universal vs. Automation Tips

✅ Universal Tips

Universal tips are designed to fit most manual pipettes from major brands (Gilson, Eppendorf, etc.). They offer a secure seal and consistent performance across a wide range of pipettes. For Rainin pipettors, please note that LTS (LiteTouch) tips are a separate type and not interchangeable with universal tips.

✅ Automation Tips

Automation tips are specially designed for automated liquid handling systems (Tecan, Hamilton, Beckman, Agilent, etc.). They feature tighter dimensional tolerances, conductive options for liquid level detection, and are often available in filtered versions.

📊 Quick Selection Guide

Application	Tip Type	Recommendation
PCR / qPCR	Filtered	Prevents cross-contamination
Toxic / radioactive samples	Filtered	Protects user and pipette
Viscous samples	Low Retention	Minimizes residue
Precious reagents (<10μL)	Low Retention	Maximizes recovery
Routine buffer dispensing	Standard / Non-Filtered	Most economical
High-throughput automation	Automation Tips	Designed for robotic systems
Manual pipetting (mixed brands)	Universal Tips	Fits most pipettes (except Rainin LTS)

❌ Common Mistakes When Choosing Pipette Tips

• Using non-filtered tips for PCR – Risk of cross-contamination and false results.
• Mixing different tip styles between pipettes – Can cause inconsistent sealing and inaccurate volumes.
• Reusing tips for viscous samples – Residue buildup affects accuracy and may contaminate subsequent samples.
• Using non-conductive tips on automation systems – May interfere with liquid level detection and cause crashes.
• Assuming all universal tips fit Rainin LTS – Rainin LTS requires dedicated LTS tips; universal tips are not compatible.

❓ Frequently Asked Questions

Q: Can I use filtered tips for all applications?
A: Yes, but it's more economical to use non-filtered tips for routine work where contamination is not a concern.

Q: What is the difference between low retention and standard tips?
A: Low retention tips have a hydrophobic coating that reduces sample residue, ideal for viscous or precious samples. Standard tips are suitable for most aqueous solutions.

Q: How do I know if my pipette is compatible with universal tips?
A: Most universal tips are designed to fit Gilson-style and Eppendorf-style pipettes. For specific compatibility, contact us with your pipette model.

Q: Do you offer sterile tips?
A: Yes, sterile options (gamma irradiated) are available upon request.

Q: What is the minimum order quantity?
A: 1 rack is available for testing. Volume discounts available for bulk orders.
