Merck
Description
CAS Number: 67-56-1
Chemical Formula: CH₃OH
Molecular Weight: 32.04 g/mol
Synonyms: MeOH, Hydroxymethane, Methyl alcohol, Carbinol
Quality Level: MQ200
With their high degree of UV transmittance, low particle count, low acidity and alkalinity and low evaporation residue level, LiChrosolv® solvents are ideal for reproducible separations. Since separations are normally carried out under gradient conditions in analytical HPLC, we offer solvents in “gradient grade” as well as “isocratic grade”. This enables to minimize the gradient effect of the solvent involved.

Minerals Modified Glutamate Medium, Oxoid Preparation:
Double Strength:
Dissolve 5g of ammonium chloride in 1 litre of distilled water. To this add 22.7g of Minerals Modified Medium Base, and 12.7g of Sodium glutamate LP0124. Mix to dissolve completely. Sterilise by autoclaving for 10 minutes at 116°C; alternatively heat to 100°C for 30 minutes on three successive days.
Single strength:
Dissolve 2.5g of ammonium chloride in 1 litre of distilled water. To this add 11.4g of Minerals Modified Medium Base, and 6.4g of Sodium glutamate LP0124. Mix to dissolve completely. Sterilise by autoclaving for 10 minutes at 116°C; alternatively heat to 100°C for 30 minutes on three successive days.
Note
To improve the stability of the dehydrated medium on storage the sodium glutamate LP0124 is supplied separately and must be added to the basal medium CM0607.
The pH of the final medium is critical for optimum performance and the sterilised broth should be checked to confirm that it is at pH 6.7 before use.
Differences in heating procedures cause differences in final pH value. If necessary the heating procedure should be adjusted so that the final pH, after sterilisation is 6.7
Storage conditions and Shelf life
Store the dehydrated medium at 10-30°C and use before the expiry date on the label.
Store the prepared medium at 2-8°C.
Precautions
Presumptive positive tubes must be sub-cultured to Lauryl Tryptose Mannitol Broth CM0831 and incubated at 44°C to detect indole formation at this temperature before the identification of Escherichia coli can be made.
