| Automation Level | manual |
Universal-fit 100µL filtered pipette tips designed for molecular biology applications requiring sterile, contamination-free liquid handling. These tips feature a hydrophobic aerosol barrier filter that prevents sample carryover and protects pipettes from contamination while maintaining accuracy and precision in microvolume transfers.
Manufactured from medical-grade polypropylene and certified DNase/RNase-free, these tips are suitable for sensitive molecular biology procedures including PCR setup, nucleic acid quantification, and enzyme assays. The universal fit design ensures compatibility with most standard micropipettes from major manufacturers.
How It Works
The hydrophobic aerosol barrier filter utilizes a porous membrane positioned within the tip shaft to create a physical barrier between the sample and pipette interior. This membrane allows air passage while blocking liquid aerosols and vapor from entering the pipette shaft, preventing contamination of internal components and subsequent samples.
The medical-grade polypropylene construction provides chemical resistance and low protein binding characteristics, while the sterile manufacturing process eliminates potential nuclease contamination. The universal fit design incorporates standardized taper dimensions that create a secure seal with most micropipette shaft configurations.

Comparison Guide
| Feature | This Product | Typical Alternative | Advantage |
|---|---|---|---|
| Aerosol Barrier Protection | Hydrophobic aerosol barrier filter | Standard tips lack filtration or use basic foam barriers | Prevents pipette contamination and sample carryover in sensitive molecular biology applications |
| Material Quality | Medical-grade polypropylene | Standard laboratory-grade plastics may have higher impurity levels | Ensures chemical compatibility and reduces interference in analytical measurements |
| Nuclease Contamination | DNase/RNase-free certified | Many standard tips lack nuclease-free certification | Critical for PCR and molecular biology applications where nucleic acid integrity must be maintained |
| Pipette Compatibility | Universal fit design | Brand-specific tips require matching pipette systems | Reduces inventory complexity and allows use across different pipette brands in multi-instrument labs |
These filtered tips combine hydrophobic aerosol barrier protection with medical-grade construction and nuclease-free certification, providing comprehensive contamination prevention for sensitive molecular biology and analytical applications.
Practical Tips
Pre-wet tips with sample when working with viscous solutions or proteins to improve accuracy and reduce sample retention.
Why: Reduces surface tension effects that can cause volume inaccuracies with challenging sample matrices.
Inspect filter barrier for damage or clogging before each use, especially when working with particulate samples.
Why: Damaged filters can compromise contamination prevention and affect pipetting performance.
Verify volume accuracy with distilled water before processing samples, as filtered tips may have different characteristics than standard tips.
Why: Ensures measurement accuracy and identifies any compatibility issues with your specific pipette model.
Use appropriate personal protective equipment when handling biological or chemical samples, as the filter does not provide protection from external exposure.
Why: The aerosol barrier protects the pipette, not the operator from hazardous sample exposure.
If pipetting becomes difficult or volume accuracy decreases, check for filter saturation or blockage from sample components.
Why: Filter saturation can impede air flow and affect pipetting performance, requiring tip replacement.
Allow adequate equilibration time between aspiration and dispensing to account for the additional air volume in filtered tips.
Why: The filter chamber creates additional dead space that may require adjusted timing for optimal accuracy.

Background reading relevant to this product:
What is the filtration efficiency of the hydrophobic barrier?
Consult product datasheet for specific filtration efficiency specifications. The hydrophobic barrier is designed to prevent aerosol and vapor passage while maintaining proper pipetting performance.
Are these tips compatible with electronic pipettes?
The universal fit design is compatible with most standard micropipettes. Test fit with your specific electronic pipette model to verify proper sealing and ejection function.
What is the maximum centrifugation speed for these tips?
Consult product datasheet for maximum centrifugal force specifications. Medical-grade polypropylene construction provides good mechanical strength for typical laboratory centrifugation.
How should unused tips be stored to maintain sterility?
Keep tips in original sterile packaging until use. Store in a clean, dry environment at room temperature away from direct sunlight and chemical vapors.
Can these tips be autoclaved for additional sterilization?
Consult product datasheet for autoclave compatibility. The filter membrane may be sensitive to high temperature steam sterilization processes.
What is the dead volume retention in these filtered tips?
Consult product datasheet for specific dead volume specifications. Filtered tips typically retain slightly more sample than standard tips due to the barrier filter.
