AnaSelect for Broth is used to enrich anaerobes in broth culture. It can replace Thio broth used as back up culture for isolating anaerobes from specimens, but with improved results. AnaSelect for Broth can be used with virtually any broth medium. We recommend BHI-HK, which is formulated for anaerobes. AnaSelect Oxyrase for Broth is available in convenient dropper bottles in a six pack. It is also available in combination with BHI-HK tubes.
