Designed for water microbiology
- The low-nutrient formulation supports the recovery of slow-growing, stressed aquatic bacteria, giving more representative heterotrophic counts.
- Suitable for total viable count / heterotrophic plate count testing of water and related samples.
Ready-to-use & reliable
- Supplied as 90 mm prepared plates, 20–25 mL agar per plate.
- Pre-sterilized during production; triple-layer vacuum packaging helps protect the medium and reduce contamination, condensation and dehydration.
- Supports good growth of common test organisms including E. coli, P. aeruginosa, B. subtilis, S. aureus, C. albicans and A. niger.
- Consistent gel strength (500–650 g/cm²) and controlled pH (7.2 ± 0.2).
Typical composition (per litre)
- Yeast extract 0.5 g; Peptone 0.5 g; Casein hydrolysate 0.5 g; Glucose 0.5 g; Soluble starch 0.5 g; Dipotassium hydrogen phosphate 0.3 g; Anhydrous magnesium sulfate 0.024 g; Sodium pyruvate 0.3 g; Agar 15.0 g; Distilled water 1000 mL; final pH 7.2 ± 0.2 (25 °C).
Storage & shelf life
- Store at 2–25 °C, protected from light.
- Shelf life: 180 days from production.
How to use
- Remove the plate from storage and allow it to equilibrate to room temperature.
- Transport the whole pack to the test site.
- Inoculate and incubate inverted at the specified temperature and time.
- Observe and count colonies.
Quality indicators
- Appearance: light yellow, smooth, no cracks, no visible impurities or bubbles.
- pH qualified; gel strength 500–650 g/cm².
- Sterility: no growth after 3 days at 20–25 °C or 2 days at 30–35 °C; no obvious dehydration.
- Growth: E. coli, P. aeruginosa, B. subtilis, S. aureus, C. albicans and A. niger – typical colony size and characteristics.
Note
- For laboratory/professional microbiological use only. Single-use product; autoclave before disposal.
- Do not use plates that are cracked, dry or contaminated.
- Re-seal any unused plates and return to appropriate storage promptly.
Packaging
- 90 mm × 10 plates per pack, triple-layer vacuum packaging
