New from Cole-Parmer: GreenLight Environmental Bacterial Count Systems

Share Article

Calculate live aerobic bacteria loads in as little as 45 minutes.

For a low-cost method of measuring disinfection efficiency and contamination levels, Cole-Parmer presents the new GreenLight® Environmental Bacterial Count Systems. The systems are ideal for monitoring wastewater discharge for disinfection limits in NPDES permits, drinking water plant disinfection, and bacteria in water at beaches.

The systems measure oxygen consumption to determine the level of live aerobic bacteria. A single-use fluorescence sensor vial within a system assesses the rate of bacterial respiration. With a built-in incubator, each system is able to provide results in just 45 minutes. These results meet 40 CFR part 160 EPA requirements. They are calculated following Standard Methods (method 2710 B), providing total viable counts/aerobic plate count (TVC/APC) data.

Select from Model 910, a single-sample system for 15-mL vials, or Model 930, which is automated for high throughput with a 24-position carousel system for 15-mL vials or 48-position carousel system for 2-mL vials.
