Product Description
When precision matters in your lab, the Whatman CYL PC BL Membrane Filter (7063-2502) delivers reliable performance for critical filtration tasks. Designed for researchers, students, and educators, these polycarbonate membrane filters provide consistent pore sizes and high retention rates, making them a trusted choice for sterile filtration, particle analysis, and microbiological applications.
Available in 25mm and 47mm diameters with 0.2µm and 0.4µm pore sizes, these filters are engineered to meet the demands of modern laboratories. The black grid pattern on the filter surface allows for easy particle counting under a microscope, while the smooth, non-hygroscopic polycarbonate material ensures minimal sample absorption and maximum recovery.
Whether you’re filtering cell cultures, testing water samples, or conducting environmental monitoring, the Whatman CYL PC BL Membrane Filter ensures accuracy and reproducibility. Each pack contains 100 filters, providing ample supply for routine lab work or large-scale experiments.

Why This Filter Stands Out
Unlike traditional cellulose filters, polycarbonate membrane filters offer superior chemical resistance and thermal stability. This makes them ideal for applications involving aggressive solvents or high-temperature sterilization. The uniform pore distribution ensures consistent filtration results, reducing variability in your experiments.
For educators, these filters serve as excellent teaching tools, allowing students to visualize and count particles with ease. Researchers appreciate the filter’s compatibility with a wide range of samples, from aqueous solutions to viscous liquids, without compromising flow rates or retention efficiency.
Applications in Real-World Labs
From academic institutions to industrial research facilities, the Whatman CYL PC BL Membrane Filter finds use in diverse scenarios:
In microbiology labs, the 0.2µm variant is commonly used for sterilizing media and buffers, while the 0.4µm version is preferred for general particulate removal. Environmental scientists rely on these filters for air and water quality testing, where precise particle capture is essential for accurate data collection.
Pharmaceutical and food safety labs also benefit from the filter’s ability to trap bacteria and other contaminants, ensuring compliance with stringent quality control standards. The black grid pattern simplifies colony counting, saving time during microbial enumeration procedures.
Choosing the Right Size and Pore Size
Selecting the appropriate filter depends on your specific application. The 25mm diameter is perfect for small-volume samples or when using filtration manifolds with limited space. For larger samples or higher throughput, the 47mm diameter offers greater surface area and faster flow rates.
When it comes to pore size, 0.2µm filters are the gold standard for sterilization, effectively removing bacteria and other microorganisms. The 0.4µm option is suitable for general clarification and pre-filtration, where absolute sterility isn’t required but particulate removal is still critical.
Maintenance and Storage Tips
To maximize the lifespan of your Whatman CYL PC BL Membrane Filters, store them in a cool, dry place away from direct sunlight. Avoid touching the filter surface with bare hands to prevent contamination. For best results, use tweezers or gloves when handling.
Before use, inspect each filter for damage or defects. If using for sterile applications, autoclave the filters at 121°C for 15 minutes. After filtration, dispose of used filters according to your lab’s biohazard waste protocols.
FAQs
What is the difference between 0.2µm and 0.4µm Whatman PC membrane filters?
The 0.2µm filter removes bacteria and most microorganisms, making it ideal for sterilization. The 0.4µm filter is used for general particulate removal where absolute sterility isn’t required.
Can these filters be autoclaved?
Yes, Whatman CYL PC BL Membrane Filters can be autoclaved at 121°C for 15 minutes without affecting their performance.
Are these filters compatible with organic solvents?
Absolutely. Polycarbonate membrane filters exhibit excellent chemical resistance, making them suitable for use with most organic solvents.
How do I count particles using the black grid pattern?
Place the filter on a microscope slide and view under low magnification. The grid lines help in systematically counting particles across the entire filter surface.
