Compact Dry X-SA | Staphylococcus aureus

Compact Dry X-SA plates let quality teams verify Staphylococcus aureus levels—a critical check of personnel hygiene and sanitation. Each pre-sterilized dish contains selective agents and a chromogenic substrate. Target colonies develop as light-blue to blue circles, while background flora are suppressed for clear, accurate counts. Compact Dry X-SA streamlines S. aureus monitoring, delivering clear, next-day results that keep hygiene programs on track and products safe. Key Benefits AOAC Performance Tested Method – validated for regulatory confidence. True “open → inoculate → incubate” workflow – no agar prep, spreading, or autoclaving. Distinct chromogenic read-out – blue colonies stand out against a pale background, making enumeration fast and photo-documentation effortless. Hygiene sentinel – ideal for detecting post-process contamination in dairy, meat, confectionery, ready-to-eat meals, and environmental swabs. Ambient-stable & stackable – store at 1 – 30 °C; slim plates fit densely in incubators to maximise capacity. Supports HACCP & personnel monitoring – high counts flag inadequate hand-washing, glove changes, or cleaning procedures. Incubation parameters Temperature Time 37 ± 1 °C 24 ± 2 h pH tip: Adjust the product (or 1 : 10 dilution) to pH 6 – 7 with 0.1 – 1 N NaOH (acidic samples) or HCl (alkaline samples) to ensure optimal colony development. Performance Countable range: 1 – 300 CFU per plate (1 mL inoculum).
