Germall 115, reduced sodium

Application
Use Germall 115, reduced sodium as preservative in combination with other
biocides to obtain the best possible antimicrobial effect in tests that require a
low concentration of sodium.
Benefits
■ Take advantage of the strongly reduced concentration of sodium.
■ Combine Germall 115, reduced sodium with non-ionic, ionic detergents
or proteins.
■ Use Germall 115, reduced sodium in your preferred combination in liquid
reagents to obtain the most stable system.
CAS: 39236-46-9
Properties
Formula: C11H16N8O8 x H2O
Molecular weight: 406.31 D
Antimicrobial effect: Only moderate effect against fungi and yeast; should be
used in combination.
Possible combination: Can be combined with all biozides which do not seperate
formaldehyde, especially 5-bromo-5-nitro-1,3-dioxane (BND), 2-hydroxypyridine-
N-oxide (HPO) or N-methylisothiazolone (MIT).
Effect: Belongs to the ''formaldehyde-depot-substances''. Inactivating effect
due to reactions with -COOH, -NH2, -OH and -SH of all proteins.
Toxicity: Harmless at recommended concentrations; not carcinogenic or mutagenic
(Ames-test negative).
Recommended working concentration: 2.6 mg/ml
pH optimum: 4.5-8.5
Stability: At pH 6 and heating up to >+60°C this product decomposes with
separation of formaldehyde.
