General description
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.
Features and Benefits
- Biologically inert with good thermal stability.
- Black plain and black gridded membranes have a mix of cellulose nitrate and cellulose acetate.
- Excellent contrast for easier particle detection., Grids are nontoxic and do not inhibit bacterial growth, ensuring sample integrity.
- Higher dirt loading capacity., No surfactants to contaminate samples.
- Sterile options available for critical applications., The membrane offers a high degree of internal surface area for greater adsorption of product.
- Uniform microporous structure of membrane gives high flow rates.
