Description

Mixed Cellulose Ester Circle ME Range
ME 27- 0.8 UM pore size
ME 28- 1.2 UM pore size
ME 29- 3.0 UM pore size
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
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
Eased counting process:
In microbiological colony counting procedures, the color contrast between the surface and the colonies facilitates the counting process
Plain or gridded:
Many microbiological techniques include colony counting after incubation as the standard method of quantitation
Whatman gridded filters have clearly defined grid lines spaced at 3.1 mm 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
Sterile filters:
For those laboratories preferring to use membranes sterilized by autoclaving for microbiological work, Whatman provides black gridded membranes in packs with pads ready for laboratory autoclaving
