Premium filtered pipette tips engineered for precision liquid handling in molecular biology and cell culture applications. These 200μL capacity tips feature integrated 0.2μm hydrophobic filters that prevent aerosol contamination and sample cross-contamination during pipetting operations. The low-retention polypropylene surface minimizes sample loss, particularly important when working with viscous solutions or precious samples.
Each tip undergoes sterilization and testing to ensure DNase/RNase-free status, making them suitable for PCR, qPCR, and other nucleic acid-based assays. The universal design fits major pipette brands including Gilson, Eppendorf, Thermo Fisher, and others. Supplied in convenient 96+4 tip racks that integrate with automated liquid handling systems and support efficient manual pipetting workflows.
How It Works
The integrated hydrophobic filter creates a physical barrier between the pipette shaft and the liquid sample, preventing aerosol formation during aspiration and dispensing. The 0.2μm pore size blocks bacteria, fungi, and most viral particles while allowing air passage for proper pipette function. During aspiration, the filter prevents sample from entering the pipette air displacement system, eliminating carry-over contamination between samples.
The low-retention surface treatment reduces van der Waals forces and electrostatic interactions between the tip material and sample liquids. This minimizes sample adherence to the tip walls, improving dispensing accuracy and reducing sample loss. The polypropylene construction provides chemical resistance to most laboratory solvents and biological samples while maintaining dimensional stability across temperature variations.

| Feature | This Product | Typical Alternative | Advantage |
|---|---|---|---|
| Filter Pore Size | 0.2μm hydrophobic filter integrated into each tip | Entry-level filtered tips may use larger pore sizes or less effective filtration materials | Smaller pore size provides more complete protection against bacterial and viral contamination |
| Volume Range | 20-200μL capacity range | Some alternatives offer narrower volume ranges requiring multiple tip types | Single tip type covers most common molecular biology and analytical volumes |
| Surface Treatment | Low-retention polypropylene surface | Standard tips may lack surface treatment leading to sample retention | Improved accuracy and reduced sample waste, particularly important for expensive reagents |
| Sterility Assurance | Gamma sterilized, DNase/RNase-free certified | Some alternatives may only provide basic sterility without enzyme-free certification | Comprehensive contamination protection for sensitive molecular biology applications |
| Packaging Format | Bulk pack of 20,000 tips (20 boxes) | Smaller quantity packages common in the market | Reduces per-tip cost and ordering frequency for high-volume laboratories |
| Rack Configuration | 96+4 tip racks with universal pipette compatibility | Some alternatives use proprietary rack designs limiting equipment compatibility | Flexible use across different pipette brands and automated systems |
These filtered tips combine comprehensive contamination protection through 0.2μm filtration with practical bulk packaging and universal compatibility. The low-retention surface treatment and DNase/RNase-free certification address critical requirements for molecular biology and cell culture applications.
Practical Tips
Pre-wet tips with sample solution 2-3 times before final measurement when working with viscous samples or when maximum accuracy is required.
Why: Equilibrates the tip surface and minimizes volume variations due to surface tension effects.
Replace tips immediately if any liquid enters the pipette shaft or if the filter appears wet or discolored.
Why: Compromised filters can lead to cross-contamination and inaccurate volume delivery.
Use consistent pipetting speed and maintain vertical tip orientation during aspiration and dispensing.
Why: Uniform technique minimizes air bubble formation and ensures reliable filter performance.
Never reuse filtered tips between different samples or reagents, even within the same experiment.
Why: Single-use design is critical for maintaining sterility and preventing cross-contamination.
If experiencing poor liquid pickup, check that the tip is fully seated on the pipette shaft without over-tightening.
Why: Proper tip attachment ensures optimal seal and prevents air leaks that affect volume accuracy.
Store opened tip racks in low humidity environments to prevent moisture absorption that could affect filter performance.
Why: Dry conditions maintain filter hydrophobicity and prevent premature degradation.
Allow a brief pause at the bottom of the aspiration stroke when working with high surface tension liquids.
Why: Ensures complete liquid transfer and prevents volume shortfalls due to incomplete aspiration.

Compliance
What is the filtering efficiency and pore size of the integrated filters?
The hydrophobic filters feature 0.2μm pore size, effectively blocking bacteria, fungi, and most viral particles while allowing air passage for proper pipette function.
Are these tips compatible with automated liquid handling systems?
Yes, the 96+4 tip rack format is designed for compatibility with standard automated pipetting systems and follows industry-standard dimensions.
How should I handle tips when working with volatile organic solvents?
While polypropylene construction provides broad chemical compatibility, consult the product datasheet for specific solvent compatibility data and consider pre-testing with your specific reagents.
What is the shelf life and storage requirements for these filtered tips?
Store in original packaging at room temperature in low humidity conditions. Shelf life typically extends 3-5 years when stored properly, but verify lot-specific dating.
Can these tips be autoclaved for additional sterilization?
Tips are pre-sterilized by gamma irradiation. Additional autoclaving may compromise filter integrity and low-retention surface properties.
How do I know if the filter has been compromised during pipetting?
Replace tips immediately if liquid enters the pipette shaft or if you observe moisture in the filter area, indicating filter breach.
What is the accuracy specification for volume delivery with these tips?
Accuracy depends on pipette calibration and technique. Tips are manufactured to tight dimensional tolerances - consult pipette manufacturer specifications for volume accuracy data.
