In October 2021, the Ministry of the Environment announced the revision of environmental standards related to water quality pollution. As a result of this revision, the standards concerning E. coli have been revised from total coliform counts to E. coli counts. The method for measuring E. coli counts is indicated as the so-called membrane filter (MF) method, which uses a membrane filter with a diameter of 47 mm and a pore size of 0.45 µm. In particular, when measuring E. coli counts, it is necessary to "store the sample in a dark place at 0-5°C (not frozen) if testing cannot be performed immediately after sampling, and it is desirable to test within 9 hours, and within 12 hours at the latest." Therefore, a micro funnel that can be used immediately after opening the bag without the need for prior sterilization is recommended. Cytiva's MicroFunnel integrates a funnel and filter, equipped with a membrane filter of diameter 47 mm and pore size 0.45 µm required for the MF method. The MicroFunnel can be easily detached by simply pinching the cylindrical part, making membrane recovery easy. It can also be connected to standard laboratory manifolds. Each unit is provided in individually packaged, gamma-sterilized form.

Cytiva's individually packaged, sterilized membrane filters and filter funnels ensure microbial analysis in accordance with the membrane filter method (MF method). The GN-6 Metricel membrane, made of cellulose mixed esters, has established global standards for strict microbial control. Supor and Metricel black membranes further offer the advantages of low adsorption of drugs and proteins, as well as vibrant background color contrast that facilitates colony counting. These membranes provide customers with uniform and stable microbial culture. The MF method is efficiently executed with micro funnels that integrate the funnel and membrane. Equipped with membranes of 47 mm diameter and pore sizes of 0.45 µm or 0.2 µm, the funnel can be easily detached from the base by simply pinching it, allowing for easy handling of the membrane. It can be directly connected to standard laboratory manifolds and features graduated markings for easy measurement of sample volume. Each unit is provided in gamma-sterilized individual packaging, accompanied by a label for lot tracking for warranty purposes.

Legionella bacteria are gram-negative bacteria widely found in soil, rivers, and lakes. When these Legionella bacteria contaminate public bath facilities, hot water systems, or filtration devices, they can infect the human body and potentially cause severe infections such as Legionnaires' disease. Therefore, testing for Legionella bacteria is conducted by various analytical companies worldwide for the purpose of environmental purification management. In May 2017, ISO 11731, which describes methods for counting Legionella in environmental water, was revised, and it proposed a "filtration concentration method using a membrane filter" for the concentration of water samples. Additionally, a direct attachment method for capturing Legionella has also been proposed. Pall handles membrane filters that meet the conditions specified in this ISO 11731.
