Pipettor Filter Element - Hydrophobic Solutions from China Suppliers and Factory for Contamination Control
Special Function Tip
■ Double Layer Pipette Tips
The filter element for double-layer tips is suitable for pipetting work with special requirements for pollution protection in molecular biology and cell biology, especially for infectious and dangerous sample operations such as pathogenic microorganisms and viruses.
■ Active Carbon Pipette Tips
Activated carbon tip filter element has a better effect of adsorbing active substances than ordinary tip filter element. On the surface of the UHWM-PE material particles of the ordinary filter element, the porous activated carbon with high activity is staggered. The activated carbon filter element can not only break the aerosol, but also better break the active molecule. The filter element is conductive, and the liquid level can be easily designed control.
■ Self-Sealing Tip Filters
Advanced self-sealing barrier technology to prevent liquid bypass and protect pipettes from contamination.
Triple Guarantee
Reduce the spread of harmful samples and protect the health of operators.
Prevent cross-contamination between samples and contamination of impurities inside the pipette, ensure that the samples meet the requirements of subsequent experiments (no DNase/RNase, no PCR inhibitors, etc.), and minimize sample loss.
Avoid liquid overshoot into the pipette cavity, maintain the precision and accuracy of pipetting, and prolong the service life of the pipette.

Pipettor Filter Advantages
Hydrophobic cartridges (e.g. polyethylene/PTFE) block 99.5% of aerosols, droplets and microorganisms, significantly reducing the risk of cross-contamination.
E-beam sterilization ensures the absence of RNase/DNase, pyrogens, and PCR inhibitors to meet PCR cleanliness standards.
Special process (e.g. “pearl effect” technology) reduces the residue of precious samples (proteins, nucleic acids) and improves the recovery rate by more than 20%, which is suitable for highly sensitive experiments such as PCR and sequencing.
Precision molding, smooth inner wall, suitable for mainstream pipettes (e.g. Eppendorf, Thermo), avoiding leakage errors.
Pipette protection: Filter cartridges block corrosive/volatile liquids from entering the interior of the device, prolonging its service life.
Chemical resistance: Resistant to organic solvents and autoclaving (-80°C~121°C).
Clean Manufacturing: Fully automated manufacturing in a 100,000 class clean room, in accordance with ISO 9001 standards.
Third-party verification: Each batch is independently tested (e.g. Fraunhofer Institute) to ensure reliable performance.
Frequently Asked Questions
What applications are double layer pipette tips best suited for?
Double-layer tips are highly suitable for pipetting tasks requiring strict pollution protection in molecular and cell biology. They are especially recommended for handling infectious and dangerous samples like pathogenic microorganisms and viruses.
How do active carbon pipette tips compare to ordinary filter tips?
Active carbon tips offer superior adsorption of active substances. High-activity porous activated carbon is integrated with UHWM-PE particles to block aerosols, break active molecules, provide electrical conductivity, and facilitate easy liquid level control.
How does the triple guarantee benefit laboratory workflows?
The guarantee covers three areas: Personnel safety (reducing harmful sample spread), Sample safety (preventing cross-contamination and DNase/RNase contamination), and Equipment safety (preventing liquid overshoot to preserve pipette accuracy and lifespan).
What sizes and models are available for the pipette filters?
We offer a wide range of models (from Model 01 to 38) with diameters ranging from 1.4 mm to 14.2 mm and thicknesses from 1.6 mm to 12.5 mm, supporting volume capacities from 10μL up to 10mL.
What makes these pipette filters ultra-hydrophobic?
Our filters feature a specialized "pearl effect" surface technology. This ultra-hydrophobic treatment reduces sample retention for proteins and nucleic acids, boosting sample recovery rates by over 20%.
Are the pipette filters certified sterile?
Yes, all filters undergo E-beam sterilization, certifying them free from RNase, DNase, pyrogens, and PCR inhibitors to comply with strict lab standards.
