E.coli & Thermostable Coliform Count Plate

1. Product Overview

FSTest E. coli & Thermostable Coliform Count Plate is a ready-to-use, single-use dehydrated culture medium system engineered for the rapid, precise, and cost-effective detection and enumeration of Escherichia coli (E. coli) and Thermostable in food, beverage, and environmental samples.

Utilizing dual chromogenic substrates (X-Gluc/Salmon-Gal), the count plate targets specific β-glucuronidase and β-galactosidase activities at 44.5℃. This reliably detects thermotolerant coliforms—a key indicator of enteric pathogen contamination—with E. coli forming distinct blue colonies and other thermotolerant coliforms showing purple-red or blue, ensuring clear, accurate visual interpretation.

2. Key Benefits

• Fast Time-to-Result: Delivers definitive colony counts in just 15–24 hours, saving up to 24–48 hours compared to traditional culture and MPN methods.

• Ready-to-Use & Zero Media Prep: No glass Petri dishes, autoclaving, or agar preparation required—simply inoculate, incubate, and read.

• High Sensitivity & Accuracy: Detection limit as low as 1–10 CFU/mL (g), ensuring compliance with strict international food hygiene standards.

• Unambiguous Visual Reading: Highly specific chromogenic reaction produces vivid purple-red or blue colonies, drastically reducing manual counting errors and false results.

• Space & Cost Efficiency: Ultra-thin paper-film format takes up minimal storage and incubator space, while significantly reducing biohazard disposal waste and shipping costs.

• Flexible Transport & Long Shelf Life: Stable at ambient temperatures (up to 15 days of room temperature shipping without cold chain reliance) with a 18-month shelf life under standard refrigeration.

5. Test Procedure

6. Performance & Validation

• Based on chromogenic enzyme-substrate technology, this count plate enables rapid differentiation and enumeration of target bacteria in water samples after incubation at 44.5℃ for 15–24 hours, with E. coli forming blue colonies and total thermotolerant coliforms appearing as blue or purple-red colonies.
