Sample Filters

Manufactured from 100% pure PTFE, these membranes represent a cutting-edge solution for ventilation, filtration, and protection in industrial and scientific environments. Thanks to an engineered production process, they are available in expanded or sintered PTFE configurations, ensuring high performance and reliability.

Designed to meet the most critical challenges in the medical, environmental, and industrial sectors, these filtration membranes can retain particles as small as 0.1 micron, maintaining their efficiency even in environments with temperatures up to 500°F (260°C).

Thanks to its exceptional chemical resistance, thermal stability, and long-term durability, microporous PTFE is an essential component for applications requiring maximum efficiency in separation and protection against contaminants.

Applications

Clarification of acids, bases, and solvents – Ideal for purifying chemical solutions without the risk of contamination.

Air quality monitoring – Essential for the collection of particulates and gases in air quality analytical instruments.

Gas filtration and venting – Ensures efficient removal of impurities, protecting devices from contaminants.

UV spectroscopy – Used in advanced optical analysis, providing optical transparency and chemical stability for high-precision measurements.

Thanks to its exceptional chemical resistance, thermal stability, and long-term durability, microporous PTFE is an essential component for applications requiring maximum efficiency in separation and protection against contaminants.
