Standardized for susceptibility testing
- The balanced formulation supports clear, well-defined zones of inhibition around antimicrobial disks.
- Consistent agar depth and gel strength (500–650 g/cm²) help produce reproducible zone measurements.
Ready-to-use & reliable
- Supplied as 90 mm prepared plates, 20–25 mL agar per plate.
- Pre-sterilized, triple-layer sterile packaging helps protect the medium and reduce contamination, condensation and dehydration.
- Supports good growth of common quality-control organisms including Escherichia coli, Staphylococcus aureus and Pseudomonas aeruginosa.
- Controlled pH (7.0–7.4) and sterility-tested.
Typical composition (per litre)
- Animal tissue enzymatic digest 6.0 g; Casein enzymatic digest 17.5 g; Soluble starch 1.5 g; Agar 13.0 g; Purified water 1000 mL; final pH 7.2 ± 0.2 (25 °C).
Storage & shelf life
- Store upright at 2–8 °C, protected from light.
- Avoid temperature swings over 10 °C, which can cause condensation.
- Shelf life: 3 months (90 days) from production.
How to use
- Remove the plate from cold storage and allow it to equilibrate to room temperature (place upright 4–6 hours before use to reduce surface moisture).
- Transport the whole pack to the test site.
- Inoculate and incubate inverted at the specified temperature and time.
- Observe and measure zones of inhibition.
Quality indicators
- Appearance: light yellow, smooth, no cracks, no visible impurities or bubbles.
- pH 7.0–7.4; gel strength 500–650 g/cm².
- Sterility: no growth after incubation for 2 days.
- Growth: E. coli, S. aureus and P. aeruginosa – good growth.
Note
- For laboratory/professional microbiological use only. Single-use product; autoclave before disposal.
- Do not use plates that are cracked, dry or contaminated.
- Minor moisture inside the pack does not affect normal use; excess moisture can be removed under sterile conditions.
Packaging
- 90 mm × 10 plates per pack, triple-layer sterile packaging
