Recommended for clarification and sterilisation of aqueous solutions, microbiological analysis and particle counts

• Membranes with grid lines are ideal for microbiological analysis (bacterial counts) of water, pharmaceuticals, beverages, cosmetics, etc. for the measurement of coliform bacteria and other germs
• Gridded membranes (black grid on white membrane) for counts of colonies as a standard method of quantification, black grid, clearly defined sections (3.1 x 3.1 mm grid)
• Special ink, non-toxic and totally free from bacterial growth inhibitors, is used for imprinting
• Sterilised membranes (packaged in individual blisters)
