Compact Dry PA | Pseudomonas aeruginosa

Compact Dry PA plates offer a straightforward way to monitor Pseudomonas spp.—especially the spoilage-prone Pseudomonas aeruginosa—in foods, beverages, cosmetics, and pharmaceutical products. Each pre-sterilized dish contains selective agents and chromogens. Target colonies develop as red centers with a green-to-yellow pigment halo, while background flora are suppressed, giving you a clear, countable result. Compact Dry PA streamlines Pseudomonas testing—delivering clear, reliable results that help protect product quality and extend shelf life. Key Benefits True “open → inoculate → incubate” workflow – no agar prep, spreading, or autoclaving. Distinct chromogenic read-out – pigmented colonies stand out for fast interpretation and photo records. Psychrotroph detection – ideal for verifying refrigerated foods where Pseudomonas drives shelf-life loss. Ambient-stable & stackable – store at 1 – 30 °C; slim profile maximizes incubator capacity. Versatile industry coverage – supports QC programs in meat, seafood, dairy, cosmetics, and pharma plants. Incubation parameters Temperature Time 35 ± 1 °C 48 ± 3 h pH tip: Adjust the product (or 1 : 10 dilution) to pH 6 – 7 with 0.1 – 1 N NaOH (acidic) or HCl (alkaline) to ensure optimal colony development. Performance Countable range: 1 – 300 CFU per plate (1 mL inoculum).
