Mixed Cellulose Ester Membranes-Plain ME 24, Gridded
10 in stock
Whatman gridded filters have clearly defined grid lines spaced at 3.1 or 5 mm intervals.
The special ink used is nontoxic and completely
free from bacterial growth inhibitors.
Whatman black mixed cellulose esters are available plain for automatic colony
counting applications, as well as gridded to assist in manual counting procedures.
Black membranes provide contrast between residue or cell colors and the filter
without having to counter-stain the membrane.

Whatman mixed cellulose ester membranes are composed of cellulose acetate and cellulose nitrate.
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.
Features and benefits
• Sterile options available for critical applications
• Excellent contrast for easier particle detection
• Grids are nontoxic and do not inhibit bacterial growth, ensuring sample integrity
• Black plain and black gridded membranes have a mix of cellulose nitrate and cellulose acetate
• The membrane offers a high degree of internal surface area for greater adsorption of product
• Higher dirt loading capacity
• Biologically inert with good thermal stability
• No surfactants to contaminate samples
• Uniform microporous structure of membrane gives high flow rates
• Thermally stable
Applications
The membrane is particularly effective in applications requiring higher flow rates and larger volume filtration,
including clarification or sterilization# of aqueous solutions, particulate analysis and removal, air monitoring
and microbial analysis. Other applications include:
• Cytology
• HPLC samples (aqueous)
• Biological assays
• Food microbiology, including enumeration of E. coli in foods
• Bacteriological studies
• Particle counting from liquids and aerosols
• Yeasts and molds
