Membrane disc filter for testing Legionella bacteria
Ideal for water concentration in Legionella testing at public bath facilities!
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.
basic information
〇 Filtration Concentration Method ISO 11731 Specification: Membrane filter made of polycarbonate or polyethersulfone (PES) with a pore size of 0.2 µm and a diameter ranging from 47 mm to 147 mm. Applicable Product: Supor 200 membrane disc membrane, 0.2 µm, 47 mm - 142 mm. This is a membrane disc filter made of Supor (PES). It is useful for testing Legionella species as specified by ISO 11731. 〇 Direct Adhesion Method ISO 11731 Specification: Membrane filter made of nitrocellulose or cellulose mixed esters with a pore size of 0.2 or 0.45 µm and a diameter ranging from 47 mm to 50 mm. Applicable Product: GN-6 Metricel membrane, 0.45 µm, 47 mm, white, without grid, gamma-ray sterilized. This is a disc filter with a GN-6 Metricel membrane made of cellulose mixed esters.
