Agar Bacteriological (Agar No.1) 500g, Oxoid

RM399.00
Brand:

Thermo ScientificTM OxoidTM

Agar Bacteriological (Agar No. 1, Oxoid) is a clear purified high gel strength bacteriological agar compatible with all culture media. This agar has low calcium (Ca) and magnesium (Mg) levels and has very high working gel strength (1.5% w/v).

Agar Bacteriological, Oxoid is compatible with all culture media. It can be formulated to either broth or agar of the same medium with very similar metal values. This characteristic is especially valuable in antimicrobial MIC studies where differences in mineral/metal content can profoundly influence the results. Due to the low mineral/metal content in Agar Bacteriological, Oxoid, it allows free diffusion of antimicrobial substances. As a result, it is a highly satisfactory agar for antimicrobial diffusion studies (disc diffusion susceptibility tests).

Basic Fuchsin – Technical Dye (10G)

RM143.00
Brand:

Thermo ScientificTM OxoidTM

Oxoid Basic Fuchsin Indicator is a dye for use with Endo Agar Base, Part No. CM0479B and m Endo (LES) Agar Base, Part No. MM0551B.

Basic Fuchsin Preparation:

BR0050 should be dissolved to create a 10% w/v solution using 95% ethyl alcohol.

For each litre of culture medium use the amount described in the product reconstitution details.  This should be in a 10% w/v solution of the dye dissolved in 50:50 ethanol/distilled water.  E.g. For CM0479 add 6ml of a 10% w/v Basic Fuchsin solution per litre of medium.

The magenta dyes are closely related to known carcinogenic substances; therefore basic fuchsin should be handled with care, avoiding inhaling the powder or staining the skin with dye.

Thermo ScientificTM OxoidTM

Isolate and presumptively identify enterococci / Group D streptococci with Thermo Scientific™ Oxoid™ Bile Aesculin Agar (Dehydrated). Bile Aesculin Agar is designed to differentiate between Group D streptococci and non-Group D streptococci.

Group D streptococci hydrolyse aesculin to form aesculetin and dextrose. Aesculin hydrolysis is indicative of a positive result. Bile salts in the medium inhibit Gram-positive bacteria other than enterococci/ Group D streptococci.
