FSTest Coliform Count Plate (Gel-Type) – Fast and Precise Microbial Detection

Product Overview

The FSTest Coliform Count Plate (Gel-Type) is a ready-to-use, disposable culture medium system designed for the rapid enumeration of coliform bacteria in food, raw materials, and water samples. Featuring advanced integrated gel technology, this plate simplifies complex laboratory procedures into a streamlined, high-performance workflow.

Key Advantages & Performance

Compared to traditional paper-based or non-gel alternatives, the FSTest Gel-Type system provides superior structural and functional benefits:

Ø Integrated Gel Technology: The all-in-one gel molding ensures uniform medium distribution and prevents "colonies growing under the paper," a common issue in multi-layered dry film products.

Ø High-Load Capacity: While traditional plates often face counting difficulties with concentrated samples, FSTest maintains clear visibility and readability even with high-load samples up to 500 CFU.

Ø Superior Diffusion Control: Our advanced gel formulation ensures zero diffusion of colonies, preventing overlapping and ensuring distinct, isolated red spots for precise counting.

Ø Enhanced Readability & Consistency: Coliforms are easily identified as red colonies associated with trapped gas bubbles. This high contrast reduces operator error and improves consistency between different users.

Ø Automation Friendly: The uniform colony distribution and clear backgrounds make these plates better suited for automated colony counters compared to paper-based alternatives.

Core Technical Specifications

Operating Procedures

Step 1: Dilution- Homogenize 25 g/mL of sample with 225 mL diluent (1: 10), then perform serial dilutions (e.g., 1: 100) as needed.Purpose: Adjust sample concentration to ensure colony counts fall within the optimal range.

Step 2: Inoculation- Lift the top film, add 1 mL of sample to the center, and replace the film carefully to avoid air bubbles.Note: Air bubbles may interfere with colony growth and counting.

Step 3: Spread & Set- Use a spreader to distribute the sample evenly, then let the plate sit for 10 seconds to allow the gel to solidify.Function: Ensures uniform sample distribution and stable gel structure.

Step 4: Incubation-Stack plates horizontally (up to 20 high) and incubate at 36 ± 1°C for 18–24 hours (or 30 ± 1°C for dairy samples).Condition Adjustment: Temperature and time vary by sample type to optimize coliform growth.

Step 5: Counting- Count red colonies with gas bubbles (optimal range: 15–150 CFU), then multiply by the dilution factor to get the final concentration.Standard: 15–150 CFU ensures accurate and reliable counting results.
