Cellulose Nitrate Membranes 0.8 μm White, Black Grid Typical Applications Microbiological examination of hard-to-filter products and applications where a higher flow rate is required. Microbiological testing of airborne bacteria. Special Features – Excellent culture medium Technical Advantages – Grid does not inhibit microbial growth. – The high flow rate allows fast filtration and is better for hard-to-filter products. – Larger pore size promotes growth of microorganisms linke Alicyclobacillus and some yeasts and molds. – Can be used for airborne microbes at places with high air humidity. White, 0.65 μm | 0.8 μm Applications and Features Typical Applications Cell retention, sample pretreatment, particle retention, clarifying filtration etc. Special Features – Higher flow rate – High non-specific adsorption Technical Advantages – Good retention rate for larger particles due to the high non-specific adsoption – High flow rate Typical Performance Adsorption, Non-specific The non-specific adsorption decreases with increasing pore size, see example for γ-globulin 0.45um gridded Typical Applications Microbiological testing of water, pharmaceutical, foods, beverages and many other products for E. coli and coliforms bacteria. Special Features – Excellent growth medium – Promotes perfect development of the typical colony morphology of bacteria on all culture media Technical Advantages – Does not inhibit growth at grid – The modified pore structure gives a higher recovery rate for E. coli and coliforms than traditional membrane types 11406 and 13906 0.45um white Typical Applications Residue analysis, hybridity testing, liquid scintillation, ultracleaning of aqueous solutions. Special Features – Fine, uniform pore structure and high, non-specific adsorption. Technical Advantages – Effective removal of small particles on filter surfaces. – Excellent for the filtration of water and other samples for clearing and reduction of the bioburden when sterile filtrati
