The quantitative disk, combined with a programmable quantitative sealing machine, provides a simple, fast, and accurate experimental plan for quantitative detection of total coliforms, fecal (heat-resistant) coliforms, and Escherichia coli.

1. The quantitative tray is packaged sterile to avoid cross contamination during use

2. The 51 well quantitative plate can detect total coliforms and Escherichia coli or fecal coliforms of ≤ 200MPN/100mL without dilution. It is generally suitable for water quality testing with strict detection limits for coliforms in drinking water, food water, bottled water, secondary water supply, pipeline water, medical water, livestock water, etc

3. The 97 well quantitative plate can detect total coliforms and Escherichia coli or fecal coliforms up to 2419MPN/100mL without dilution. It is generally suitable for water quality testing of surface water, groundwater, seawater, wastewater, and other water with high detection levels of coliforms

4. Control reduces manual operation time, greatly improving experimental efficiency

5. The quantitative disk provides a relatively high detection range with a 95% confidence interval

6. The quantitative disk has passed the sealing test, with no leakage or hole breakage. The sealed hole grid can withstand a pressure of not less than 8kg and will not cause the series connection or damage between holes due to the superposition of forces on the quantitative disk

By utilizing the simple and rapid detection characteristics of enzyme substrate method, combined with electromechanical and optical detection technology, and using programmable quantitative sealing technology and specific MPN algorithm processing, a simple, fast, and accurate experimental scheme for quantitative detection of total coliforms, fecal (heat-resistant) coliforms, and Escherichia coli is provided. Meet the detection of microbial contamination indicators in multiple scenarios such as drinking water, environmental water, etc.
