Compact Dry AQ | Heterotrophic Bacteria
Box of 100 plates
Compact Dry AQ plates provide a rapid, reliable heterotrophic plate count (HPC) for assessing the overall microbial load in water. Each pre-sterilized, dehydrated plate re-hydrates on contact with 1 mL of sample, eliminating media preparation and autoclaving. Colonies develop as easily distinguishable red or pink spots, making enumeration and downstream sub-culturing straightforward.
Ensure treated drinking water and/or ultra-pure water meets local regulatory requirements by confirming that heterotrophic counts fall within acceptable limits.
Key Benefits
- Regulatory alignment – validated for WHO drinking-water guidelines, ISO 6222:1999, and SMEWW 9215 methods.
- True “ready-to-use” format – open, inoculate, incubate; no mixing or pouring agar.
- Space-saving design – low-profile, rigid, stackable plates maximize incubator capacity.
- Ambient storage – stable for the full shelf life at 1 – 30 °C; no refrigeration needed.
- Clear colony isolation – well-defined colonies can be picked directly for confirmation tests.
Incubation Parameters
| Method (standard) | Temperature | Time |
| Filter / SMEWW 9215 | 36 ± 2 °C | 44 ± 4 h |
| ISO 6222:1999 | 22 ± 2 °C | 68 ± 4 h |
Performance
Countable range: 1 – 300 CFU per plate (based on 1 mL inoculum)
