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.

Comparison Guide

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.
