Formats available: 250 g and 500 g packs for agar/media and 5 mL×10 vials for Tellurite Yolk enrichment solution.

Key media and targets

• TAT Broth — ideal for detecting total bacterial load
• Rose Bengal Medium — isolation and enumeration of yeasts and molds
• Baird-Parker Agar & Tellurite Yolk Enrichment Solution — selective recovery and enrichment for Staphylococcus aureus
• PAP Agar & Cetrimide Agar — detection and differentiation of Pseudomonas aeruginosa (including pyocyanin determination)
• Letheen Broth and Letheen Agar — for testing products containing quaternary ammonium compounds or cationic surfactants
• HC Agar Base — platform for mold enumeration
