Low Retention Pipette Tips
Description
Product Overview
Hawach low retention pipette tips (also called low adsorption or low binding tips) are specially treated to minimize sample adhesion to the tip surface. This maximizes recovery of valuable biomolecules such as proteins, enzymes, antibodies, nucleic acids, and detergents. Available in both filter (with aerosol barrier) and ordinary (non-filter) versions, all tips are sterile, gamma irradiated, and certified DNase-free, RNase-free, and endotoxin-free. Volume range from 10μL to 1250μL, with extended length options for deep tube access. Ideal for proteomics, immunoassays, molecular biology, and any application where sample conservation is critical.
Why use low retention tips? Standard tips can bind up to 1-5% of protein or nucleic acid samples. Low retention tips reduce surface binding, recovering up to 99% of precious samples – essential for low concentration or high-value reagents.

Choose aerosol barrier (filter) for contamination-sensitive workflows or ordinary for routine low retention needs.
Sterile & Nuclease Free
Gamma sterilized, DNase/RNase free – safe for RNA/DNA applications.
Endotoxin Free
≤0.25 EU/mL – suitable for cell culture and immunoassays.
Extended Length Option
10μL extended tips reach the bottom of deep tubes without contamination.
Universal Fit
Compatible with most single and multichannel pipettes.
Selection Guide – Which Low Retention Tip to Choose?
| Application | Tip Type | Recommended Cat. No. | Why |
|---|---|---|---|
| Proteomics / protein assays / enzymes | Low retention, sterile | 21081503 (200μL filter) or 21081605 (200μL ordinary) | Minimizes protein binding, improves assay sensitivity |
| qPCR / RT-PCR (RNA sensitive) | Low retention filter, sterile | 21081501 (10μL) or 21081506 (20μL) | Aerosol barrier prevents cross-contamination, low binding for RNA |
| Antibody / ELISA workflows | Low retention ordinary | 21081604 (100μL) or 21081605 (200μL) | Reduces antibody loss, consistent results |
| Precious nucleic acid samples (e.g., CRISPR, NGS) | Low retention filter (sterile) | 21081501 (10μL) or 21081503 (200μL) | Maximizes DNA/RNA recovery, nuclease free |
| Deep tube sample aspiration | Low retention, extended length | 21081502 (10μL filter) or 21081602 (10μL ordinary) | Reaches bottom, low binding |

Frequently Asked Questions – Low Retention Pipette Tips
What is the difference between low retention (low adsorption) and standard tips?
Low retention tips have a specially treated surface that reduces sample adhesion, recovering up to 99% of precious samples. Standard tips can retain 1-5% of protein or nucleic acid samples, leading to significant loss.
Do I need filter or ordinary low retention tips?
Use filter tips for PCR, RNA work, and infectious samples – the aerosol barrier prevents cross-contamination. Use ordinary tips for general low retention needs where aerosol protection is not required.
Are these tips sterile and nuclease free?
Yes – all Hawach low retention tips are gamma sterilized and certified DNase/RNase free, safe for sensitive molecular biology applications.
Can I request a free sample?
Yes, we provide sample racks for evaluation. Contact us to request.
Are these tips compatible with multichannel pipettes?
Yes, the rack spacing is standard for 8- and 12-channel pipettes.
