Brain Heart Infusion Broth – granulated format for dust-free weighing
The granulated Brain Heart Infusion Broth is used for the cultivation of streptococci, staphylococci and other demanding bacteria and for the subculture of colonies before confirmation tests. Granules produce less dust and dissolve evenly.
- Granulated – less dust, better flow
- Rich infusion broth
- Subculture before confirmation tests
How Brain Heart Infusion Broth works
Brain and heart infusions, peptone and glucose support the growth of fastidious bacteria, and phosphate buffer keeps the pH stable. Good growth of S. aureus is checked on every lot.

Applications and practical notes
General-purpose media are the basic tools of every microbiology laboratory. They grow a wide range of non-fastidious bacteria and are used for revival of cultures, purity checks and the maintenance of reference strains, whose performance is verified according to ISO 11133. Typical applications include:
- Cultivation of non-fastidious bacteria
- Revival and maintenance of reference strains
- Purity checks and subculture
- Teaching and routine laboratory work
Working with Brain Heart Infusion Broth: Weigh the granules without grinding them and keep the bottle closed between uses.
Good practice with dehydrated media: keep the bottle tightly closed in a cool, dry place, weigh the powder quickly to avoid moisture uptake, and use fresh distilled or deionised water. Check the pH of each new batch after preparation and before use, and label prepared media with the date. Performance of each lot can be verified with reference strains according to ISO 11133, the standard for the preparation, production, storage and performance testing of culture media.
About general-purpose media: general-purpose media are not tied to one reference method. They are used in every laboratory for cultivation, revival of reference strains, purity checks and as bases for enriched and test media. Their performance is verified with reference strains according to ISO 11133, and media for susceptibility testing follow the requirements of EUCAST and CLSI. COLO.Science offers general media, enriched bases, supplements and QC strains from one source.
