Disposable filter funnels with grid membrane for the microbiological analysis of aqueous liquids in pharmaceutical production, water management as well as the food and beverage industry. Graduations with markings on the outside of the funnel make it easy to read the sample volume. Squeeze separation of the cylinder from the base provides easy access to the membrane for culturing.
Vented lid reduces the risk of contamination and closes liquid-tight to prevent leakage.
