Violet Red Bile Glucose (VRBG) Agar (ISO) (Dehydrated), Oxoid Preparation:
Suspend 38.5g of VRBGA (ISO) dehydrated medium in 1 litre of distilled water. Bring to the boil while mixing. Continue to boil for up to 2 minutes or for the minimum time necessary to dissolve completely. DO NOT AUTOCLAVE. Cool to 44-47°C and use within 4 hours. Mix well before pouring.
Storage conditions and Shelf life
VRBGA (ISO) should be stored in the tightly capped original container at 10-30°C. When stored as directed, the un-opened product will remain stable until the expiry date printed on the packaging.
Locally prepared VRBGA (ISO) plates can be stored for up to 2 weeks when made from CM1082 according to the manufacturer’s instructions and stored at 2-8°C, out of direct sunlight. A longer shelf life may be attainable, but should be validated under the relevant, local manufacturing and storage conditions.
Precautions
VRBGA (ISO) should be prepared, cooled to 44-47°C and used within 4 hours.
VRBGA (ISO) is for laboratory use only. Do not use the dehydrated medium beyond the stated expiry date or if the product shows any sign of deterioration.

Suspend 38.5g in 1 litre of distilled water. Bring to the boil. Continue to boil for 2 minutes or for the minimum time necessary to dissolve completely and ensure that there are no remaining flecks of unmelted agar. No further sterilisation is necessary or desirable. Mix well before pouring.
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 and use as freshly as possible.
Precautions
This medium is not completely specific for Enterobacteriaceae, other organisms e.g. Aeromonas and Yersinia species may give similar reactions.
The selectivity of the medium diminishes after 24 hours incubation and organisms previously suppressed may exhibit growth.

Description
CAS number: 7732-18-5
Chemical Formula: H₂O
Molar Mass: 18.02 g/mol
Synonyms: Deionized water
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.
