Membrane filter dispenser for microbiological control

Membrane filters for microbiological checks must be handled carefully to ensure that they remain sterile and that quantitative results are being obtained.

Membrane filters for microbiological quality control testing must be handled aseptically to ensure they remain sterile and provide accurate test results. Membrane dispensers provide one disc at a time by pealing open a continuous web of individually sealed discs. The Membrane Filter (MF) Technique is a reliable way to test water and wastewater, food and beverages, environmental samples and purified water systems for coliforms, E. coli, Legionella, yeast & mold, Pseudomonas, total bacteria, and other microbial contamination.
