Description
For the ultimate in quality assurance, ErtelAlsop MicroMedia LXL Series Filter Sheets are formulated with both high purity cellulose and a high quality diatomaceous earth.
The 9 grades of MicroMedia LXL Series Filter Sheets offer the combined advantages of the XL series ultra pure Diatomaceous Earth with the L series Beta glucan poor cellulose fibers to produce this superior depth filter media and making it the leading choice for Bio-pharmaceutical applications.
A particular source of extractables is 1,3 ß D-glucan contamination in the cellulose. Cellulose is a major component of depth filter products. The level of reactivity depends upon the amount of 1,3 ß D-glucans released during manufacturing of the filter media and the amount of Factor G present in the LAL reagent, which varies by manufacturer.
