Print PageThese non-sterile mixed cellulose ester (MCE) membrane filters from are suitable for culturing, enumeration of bacteria and other cell counting methods. This range have a 0.6 micron pore size.
Composed of cellulose acetate and cellulose nitrate, giving the membrane a more uniform surface than pure nitrocellulose filters.
MCE filters support microbiology applications such as E.coli culturing. The porous membrane structure enables uptake of growth media to the bacterial colonies without chemically inhibiting their growth.
- Supports visual enumeration of bacteria
- Appropriate for bacterial culturing, including E.coli
- Biologically inert with good thermal stability
- Uniform microporous structure results in high flow rates when used for filtering
Guide to…Membrane Filter Properties
Identifying the filter material most suitable for your application based upon the nature of the liquid or gas you are filtering will ensure the best performance of your filter. Each membrane filter material has differing chemical and physical properties such as hydrophobicity, flow rate, extractables and protein retention making them suited to differing applications. Once you have selected the most compatible filter material, you will need to consider what pore size is most appropriate.
