Polycarbonate Track-Etched (PCTE) Membrane Filters - 10418701
Engineered for high retention efficiency and superior chemical stability, the Whatman 10418701 achieves reliable separation results across a broad range of analytical and preparative applications. Quality-controlled manufacturing ensures the filtration medium delivers the retention efficiency and throughput that demanding laboratory protocols require. Controlled production conditions produce membranes with documented pore size distribution and thickness tolerances, supporting method reproducibility across multiple filter lots.
Material Specifications
- Low protein binding and biologically inert surface properties make track-etched Polycarbonate compatible with cell biology and cytology workflows.
- Track-etched Polycarbonate membranes feature perfectly cylindrical pores for absolute fractionation.
- Offer a smooth, flat glass-like surface specifically designed for microscopy analysis.
- Optically clear construction enables direct on-membrane visualization of captured particles without transfer or additional preparation.
- Packaged without sterilization for applications where downstream sterility is achieved by other means or is not a process requirement.
Reporting filtration parameters alongside your analytical results demands documented pore size, material chemistry, and lot traceability — the membrane specifications above provide the specificity that reviewers and auditors expect. With this in mind, polycarbonate's optical clarity when wet allows direct on-membrane visualization without clearing or staining steps, streamlining your microscopy workflow and reducing the sample preparation time between filtration and analysis. Make the decision for consistency and reliability, ensuring that your laboratory maintains its reputation for high-quality, error-free output.

- Exosome Isolation - Separates extracellular vesicles from larger cell debris using defined pore sizes, preventing contamination in RNA analysis.
- Liposome Sizing - Used in extrusion devices to force lipid suspensions through exact pores, creating uniform unilamellar vesicles for drug delivery.
- Parasite Detection - Concentrates blood samples to detect microfilariae on a transparent surface, simplifying identification without staining.
- Oceanographic Sampling - Fractionates plankton populations by size in seawater, ensuring precise separation for biomass and diversity studies.
- Legionella Recovery - Captures bacteria from hot water samples on a flat plane for direct fluorescent antibody staining and microscope counting.
- Chemotaxis Migration - Acts as a precise barrier in Boyden chambers to measure cell migration towards chemoattractants without passive diffusion.
