Product Overview
The Whatman MEMBRACLEAR membrane filter is engineered for high-efficiency filtration in laboratory settings, featuring a 0.45?m pore size that ensures reliable particle retention and sterile processing. Constructed from mixed cellulose esters (MCE), this filter combines mechanical strength with chemical compatibility, making it suitable for aqueous and mild organic solutions. Its uniform pore structure guarantees consistent flow rates, while the hydrophilic nature of the membrane enhances wetting and sample throughput. The filter?s low extractables profile minimizes interference with downstream applications, ensuring accurate results in analytical procedures. Available in 25mm and 47mm diameters, each pack contains 100 discs, providing ample supply for routine lab workflows. The membrane?s white, grid-marked surface aids in visual inspection of particulates, while its compatibility with autoclaving and gamma irradiation supports sterile applications. Whether used for clarifying solutions, microbial analysis, or sample preparation, the Whatman MEMBRACLEAR delivers precision and reproducibility, backed by Whatman?s legacy of filtration excellence.
FAQs
1. What is the pore size of the Whatman MEMBRACLEAR membrane filter?
