These 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 0.2 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
For microbiological quality control the membrane filter method is the optimal analytical method.
suitable for aqueous solutions
can be used up to 125°C
autoclavable up to 121°C
These membranes are characterized by a smoother and more uniform surface than pure nitrocellulose filters. Also, the color contrast provided by the filter surface facilitates particle detection and minimizes eye fatigue. The ME range has a lower cellulose acetate content compared to the WME range of membranes.
