Product Overview
The Whatman ME25 Membrane Filter is engineered for high-efficiency particle retention and general filtration in laboratory settings. Constructed from mixed cellulose esters (MCE), these filters provide a 0.45?m pore size, ensuring reliable separation of microorganisms, particulates, and contaminants. The uniform pore structure guarantees consistent flow rates and high loading capacity, making them suitable for demanding applications. Each filter undergoes stringent quality control to ensure sterility and compatibility with aqueous and mild organic solutions. The white, grid-marked surface allows for easy particle visualization under a microscope, while the hydrophobic nature of MCE ensures minimal extractables. Available in multiple diameters (25mm to 142mm), these filters are designed for seamless integration into standard filtration systems. Their high mechanical strength prevents tearing during handling, while the non-toxic composition ensures no interference with sensitive assays. Whether used for routine sample preparation or critical research, the Whatman ME25 delivers precision and reproducibility, backed by Whatman?s legacy of filtration excellence.
FAQs
1. What is the pore size of the Whatman ME25 membrane filter?
The Whatman ME25 membrane filter has a uniform pore size of 0.45 micrometers, optimized for retaining bacteria and fine particulates.
2. Can these filters be autoclaved for sterilization?
Yes, these filters are autoclavable at 121?C for 15 minutes, ensuring sterility without compromising structural integrity.
3. Are these filters compatible with organic solvents?
They are compatible with mild organic solvents like ethanol and acetone but may degrade with strong solvents such as DMSO or chloroform.
4. How should these filters be stored to maintain performance?
