Product Overview
The Whatman ME25/91 STL Membrane Filter is a high-performance filtration solution designed for laboratory applications requiring precision and reliability. Constructed from mixed cellulose esters (MCE), this filter offers a 0.45µm pore size, making it ideal for sterile filtration, particle retention, and clarification processes. The 50mm diameter ensures compatibility with standard filtration setups, while the pack of 400 provides ample supply for continuous lab work. Known for its consistent flow rates and low extractables, this membrane filter maintains sample integrity and ensures accurate results. The hydrophobic nature of the MCE material enhances its suitability for aqueous and mild organic solutions, while its robust structure prevents tearing or deformation during use. Whether used in routine lab procedures or specialized research, the Whatman ME25/91 STL delivers uniform performance, reducing the risk of contamination and ensuring reproducibility. Its compatibility with autoclaving further extends its utility in sterile environments, making it a versatile choice for demanding filtration tasks.
