Product number: NCM0039

Membrane Lauryl Sulphate Broth is used for the enumeration of coliforms in water and is not intended for use in the diagnosis of disease or other conditions in humans.

This medium superseded Membrane Enriched Teepol Broth when Shell Chemicals withdrew Teepol 610 from sale. Sodium lauryl sulphate was found to be an adequate reproducible substitute and this medium is recommended for the enumeration of coliform and organisms in water and sewage.
