IDEXX Colilert-18 Test

The IDEXX Colilert-18 Test is a rapid and reliable method for detecting total coliforms and Escherichia coli (E. coli) in water samples or fecal coliforms in wastewater. Providing results in 18 hours or less, this test simplifies your laboratory workflow by offering rapid results, no confirmations needed, and easy-to-read outcomes. With the Colilert-18 Test, you can monitor water quality efficiently for various applications, such as drinking water testing, wastewater analysis, and environmental monitoring.

The test uses Defined Substrate Technology (DST) with ONPG and MUG, which makes it specific for detecting coliforms and E. coli. This eliminates false positives typically found in traditional media, providing a higher level of accuracy and precision.

Key Features & Benefits:

1. Fast Results:
   • The Colilert-18 Test delivers results in 18 hours or less, allowing you to monitor microbial contamination quickly and efficiently without the need for lengthy incubation or confirmation steps.
2. Simultaneous Detection of Coliforms and E. coli:
   • The test detects both total coliforms and E. coli in one procedure, providing a comprehensive analysis of water quality in a single test.
3. No Confirmations Needed:
   • Unlike traditional testing methods, Colilert-18 requires no additional confirmatory tests, making it faster and more efficient for routine water quality monitoring.
4. Easy to Use:
   • The test is designed for simple usage with unit-dosed packaging that eliminates the need for media preparation, reducing setup time and the chance of errors.
   • Color change results are easy to read:
     • Colorless = negative
     • Yellow = total coliforms present
     • Yellow/fluorescent = E. coli present
5. Accurate and Reliable:
   • The Colilert-18 Test suppresses up to 2 million heterotrophs per 100 mL, eliminating interference from non-coliforms, and ensuring that only the relevant bacteria are detected. This provides more accurate results than traditional methods, which may give false positives due to non-target organisms.
6. Quantification and Presence/Absence Testing:
   • The test can be used for Presence/Absence (P/A) testing or quantification using the Quanti-Tray or Quanti-Tray/2000 systems, allowing for flexible testing options depending on the needs of the laboratory.
   • The Quanti-Tray system counts from 1–200 wells, while the Quanti-Tray/2000 system counts from 1–2,419 wells, making the test scalable for different levels of analysis.
7. Economical and Time-Efficient:
   • Minimizes evening and weekend work, as results are available in 18 hours, making it easier to schedule and plan for testing without needing extra time or resources.
8. Long Shelf Life:
   • The Colilert-18 Test has an up to 15-month shelf life when stored at room temperature, making it convenient for long-term use without concern for product degradation.

Applications:

• Drinking Water Testing: Ideal for detecting total coliforms and E. coli in drinking water, ensuring safety and compliance with water quality standards.
• Wastewater Analysis: Perfect for monitoring fecal coliforms and E. coli in wastewater to assess the effectiveness of water treatment processes.
• Environmental Monitoring: Useful for monitoring environmental water sources such as rivers, lakes, and reservoirs for microbial contamination.
• Microbial Water Testing: Widely used in water testing labs for routine microbial analysis of water samples to meet regulatory standards.
