Polycarbonate Filter

Track-etched polycarbonate (PC) membranes are manufactured from high-quality polycarbonate film. PC membranes have a smooth flat surface and exhibit very low levels of extractable. They have sharply defined pore sizes, high flow rates, and excellent chemical and thermal resistance. They are suitable for the detection of particles in many corrosive fluids because of this broad chemical compatibility.

Precision Particle Capture with Polycarbonate Membrane Filters

Achieve unmatched accuracy in particle analysis, microbiology, and environmental monitoring with our Polycarbonate (PC) Filter—track-etched membrane filters featuring perfectly cylindrical pores, smooth surfaces, and exceptional clarity. Engineered for applications requiring precise particle retention, imaging, and enumeration, these filters are ideal for air and liquid sampling, fluorescence microscopy, SEM/TEM analysis, and regulatory compliance testing.

Engineered for Exactness and Imaging Clarity

Unlike cast membranes, Polycarbonate Filters are manufactured using ion-track etching technology, resulting in straight-through, uniform pores with sharp size cutoffs—ensuring high capture efficiency and minimal particle migration. Their optically clear, thin (typically 6–30 µm) structure provides a near-invisible background, making them perfect for microscopic examination, particle counting, and post-filtration analysis.

True Pore Size Accuracy – Available from 0.015 µm to 12.0 µm with tight tolerances for reliable retention.
Smooth, Mirror-Like Surface – Enhances particle visibility and simplifies staining, fluorescence, or electron microscopy.
Low Autofluorescence – Ideal for fluorescent labeling and bioimaging applications.
Biologically Inert & Low Extractables – Suitable for cell culture, cytology, and sensitive analytical workflows.
Hydrophilic by Default – Can be treated for hydrophobic use in air or gas sampling.
ISO-Certified Production – Manufactured under cleanroom conditions for low endotoxin and consistent quality.

Trusted in Advanced Research and Compliance Testing

Widely used in NIOSH air sampling, waterborne pathogen detection, nanoparticle research, and pharmaceutical cleanroom monitoring, polycarbonate filters meet ASTM F795, ISO 14644, and EPA method requirements. Their mechanical strength allows handling without support rings in many applications, while their transparency enables direct on-filter analysis—reducing sample transfer errors.

Whether you’re capturing airborne microbes, analyzing microplastics, or preparing samples for high-resolution imaging, our Polycarbonate Filters deliver the precision and clarity your science demands.
