Product Overview
The Whatman ME28 Membrane Filter is engineered for high-performance filtration in laboratory settings, featuring a 1.2?m pore size that ensures efficient retention of fine particulates, bacteria, and other contaminants. Constructed from mixed cellulose esters (MCE), this hydrophilic membrane delivers consistent flow rates and superior particle capture, making it a reliable choice for critical filtration tasks. Its uniform pore structure minimizes clogging while maintaining high throughput, ideal for applications requiring precision and reproducibility. The membrane?s compatibility with a wide range of solvents and aqueous solutions further enhances its versatility, allowing seamless integration into diverse workflows. Available in multiple diameters (25MM, 47MM, 50MM, and 100MM), the ME28 filter accommodates various filtration setups, from small-scale sample processing to larger-volume applications. The pack sizes are optimized for cost efficiency, providing 100 filters for smaller diameters and 50 for the 100MM variant, ensuring you have an adequate supply for extended use. Designed for durability, the ME28 membrane resists tearing and deformation under standard operating pressures, reducing the risk of sample loss or cross-contamination. Its smooth surface facilitates easy handling and minimizes particle adhesion, simplifying post-filtration analysis. Whether used in gravity-driven or vacuum-assisted systems, this filter maintains integrity and performance, delivering reproducible results across repeated experiments. The Whatman ME28 stands out for its balance of affordability, reliability, and technical precision, making it a staple in labs where filtration quality directly impacts outcomes.
FAQs
1. What is the pore size of the Whatman ME28 Membrane Filter?
The Whatman ME28 Membrane Filter has a pore size of 1.2 micrometers, designed for efficient particulate retention.
2. Is this membrane filter compatible with organic solvents?
Yes, the mixed cellulose esters material is compatible with a range of aqueous solutions and some organic solvents, though compatibility should be verified for specific applications.
3. Can this filter be used for air monitoring applications?
