Petrifilm™ Aqua Counting Plates are ready-to-use culture media for microbiological analysis of water, compatible with both direct inoculation and membrane filtration systems. Water-soluble gelling agents, culture media, and indicators are uniformly distributed in a desiccated, balanced state on each plate. The film-backed gel matrix with culture medium is a specially engineered design by 3M™ Petrifilm™, enabling rapid, reliable analytical results while reducing analysis costs and labor requirements. Color-changing indicator colonies provide clear, quantifiable results for precise microbial enumeration.

Frequently Asked Questions

What are the four types of Petrifilm Aqua plates available?

The four plate types are: (1) Heterotrophic (Total Count) Counting Plate, (2) Coliform Counting Plate, (3) Enterobacteriaceae Counting Plate, and (4) Mold & Yeast Counting Plate, each designed for specific microbial enumeration needs in water testing.

What is the typical analysis timeframe for Petrifilm Aqua plates?

Results are typically obtained within 48-72 hours. Using membrane filtration at 35°C requires 48 hours, while direct inoculation requires either 68 hours at 22°C or 44 hours at 36°C, depending on your laboratory protocol.

Which incubation method should I use?

Petrifilm Aqua plates are compatible with both direct inoculation and membrane filtration systems. Select the method based on your laboratory's capabilities and standard protocols for water microbiological analysis.

How does the indicator system work?

Color-changing indicator colonies provide visual differentiation and clear quantification of microbial growth, enabling precise enumeration without subjective interpretation and reducing analysis time compared to traditional agar methods.
