China Suppliers Factory of Hydrophobic Pipette Filter Elements for Contamination-Free Sampling
Special Function Tip
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.
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.
High-performance self-sealing filters designed 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 PCRinhibitors, 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.
Filter cartridges block corrosive/volatile liquids from entering the interior of the device, prolonging its service life. Highly resistant to organic solvents and autoclaving (-80°C~121°C).
Fully automated manufacturing in a 100,000 class clean room, in accordance with ISO 9001 standards. Each batch is independently tested by third parties (e.g. Fraunhofer Institute) to ensure reliable performance.
Frequently Asked Questions
Double-layer tips are suitable for molecular and cell biology tasks requiring strict pollution protection, especially when handling infectious and dangerous samples like viruses and pathogenic microorganisms.
Active carbon tips have highly active porous carbon layered on UHWM-PE particles, offering superior adsorption of active substances. They block aerosols, break down active molecules, and feature electrical conductivity for easy liquid level control.
It provides a three-fold safety net: protecting personnel from harmful sample exposure, preventing sample cross-contamination (ensuring DNase/RNase/PCR inhibitor-free conditions), and shielding pipetting equipment from liquid overshoot.
The hydrophobic cartridges (polyethylene/PTFE) act as a highly effective barrier, blocking up to 99.5% of aerosols, droplets, and microorganisms.
The filters are manufactured in a class 100,000 clean room adhering to ISO 9001 standards. They undergo E-beam sterilization to guarantee they are RNase/DNase, pyrogen, and PCR inhibitor-free, with batches verified by third-party institutes like Fraunhofer.
