Product Overview

The Whatman AE99 Membrane Filter is engineered for high-performance filtration in demanding laboratory environments. Constructed from pure cellulose acetate, this membrane ensures consistent particle retention with an 8.0?M pore size, making it ideal for applications requiring precision and reliability. Its uniform structure minimizes clogging, extending filter life and maintaining flow rates during critical processes. The hydrophobic nature of cellulose acetate provides excellent chemical resistance, allowing compatibility with a wide range of solvents and aqueous solutions. Each disc undergoes strict quality control to guarantee low extractables and minimal background interference, ensuring accurate analytical results. The filter?s smooth surface and high dirt-holding capacity make it suitable for both qualitative and quantitative analyses. Available in standard diameters (25MM, 47MM, 50MM), the AE99 is designed for seamless integration into existing filtration setups, including syringe filters, vacuum manifolds, and in-line systems. Its sterilization compatibility via autoclaving or gamma irradiation further enhances its versatility for aseptic applications. Whether used for air monitoring, sterile filtration, or sample preparation, the Whatman AE99 delivers reproducible performance, reducing variability in experimental outcomes. The pack of 100 ensures cost-effective bulk availability for high-throughput labs, while the individual packaging preserves integrity until use. Trusted by researchers worldwide, this filter combines durability with precision, making it a staple in laboratories prioritizing accuracy and efficiency.
