Colifast Field Kit is a portable tool for field detection of coliform bacteria in water. The main method of the kit is a rapid method that provides an answer as early as 15 minutes, 2 hours at the latest. In addition, the kit includes methods for a quantitative MPN (Most Probable Number) method and presence/absence results. The procedure is very easy to perform, and requires no laboratory skills. Colifast Field Kit is delivered in a robust and portable metal case, and all equipment required for the water analysis is included. The Colifast Micro Detector (CMD) is used in combination with a growth medium for specific detection of target bacteria. Combined, they provide a simple instrumental analysis and rapid results that quantify the amount of coliform and thermotolerant bacteria in water. The method is based upon the patented technology of Colifast AS. The system detects down to 1 target bacterium per sample volume. Method The Colifast technology is based on a chemical reaction between a substrate in the growth medium and enzymes produced by the coliform bacteria. The bacterial enzyme β-D-galactosidase hydrolyses the substrate 4-methylumbelliferyl-β-D-galactoside, which results in the release of the fluorescent product 4-methylumbelliferone (MU). In addition to substrate, activators and growth factors, the medium comprises inhibitors that prevent the growth of non-coliform bacteria. The results are measured in fluorescent units. An increase in the number of bacteria corresponds to an increased amount of β-D-galactosidase (enzyme). The subsequent increase in the amount of MU (fluorescent product) results in a higher value on the instrument (Colifast Micro Detector). The incubation temperature selects for thermotolerant coliforms at 44 °C and total coliforms at 37 °C. -
Rapid, Automated and Remote Microbial Testing for Water and Food Safety Colifast ALARM™ is an electronic instrument for detecting indicator bacteria in drinking water using patented Colifast technology. 100 ml water samples are automatically collected at programmed intervals and analyzed for total coliforms, thermotolerant coliform bacteria or E. coli. In addition to performing rapid, online microbial water analysis, Colifast ALARM measures water turbidity. The system can automatically send results to control rooms / operators via LAN, digital signals or via mobile networks (SMS). The system can detect down to 1 cfu / 100 mL, and results are achieved within 6-14 / 15 hours. Technology The main components of Colifast ALARM are the incubator chamber, an injection pump system for fluid handling, and a detector system that includes wavelength-specific emitters combined with a spectrometer. Detection of down to 1 viable target bacteria is based on bacterial growth, group-specific enzyme activity and measured concentrations of a fluorescent product (ppb MU). An increase in the number of target bacteria means an increase in the amount of β-D-glucuronidase (E. coli-specific enzyme). The enzyme hydrolyses the growth medium substrate to MU (the fluorescent product) and β-D-glucuronic acid. Increased MU release gives increased fluorescence signal on the Colifast ALARM. Colifast growth medium contains inhibitors to prevent growth of non-coliforms. Colifast ALARM is verified by EPA's ETV program. -
Whole-cell or whole-organism external controls Empower your results and challenge your methods with SeraCare’s ACCURUN® molecular controls and reference materials. ACCURUN molecular controls and reference materials are whole-cell or whole-organism external controls that help you monitor all aspects of your molecular testing methods and provide additional confidence in your laboratory test results. A well-designed QC program can help you avoid costly false-negative or false-positive results. ACCURUN molecular controls effectively detect low-positives closer to assay-specific cutoffs, enabling better detection of assay variability. Powerful ACCURUN controls and reference materials help to ensure complete control over assay performance monitoring. Monitors the Entire Testing Process. In order to execute the highest level of quality control, QC methods should be able to monitor the entire testing process, not just a portion. ACCURUN molecular controls are whole-cell or whole-organism controls that can appropriately challenge your assay from extraction through detection. -

Empower your results and challenge your methods with SeraCare’s ACCURUN® serology controls and reference materials. SeraCare's ACCURUN controls and reference materials are designed to be weakly reactive to help monitor your serology assays and provide additional confidence in your laboratory test results. Monitoring your assay performance can help you avoid costly repeats and, more importantly, avoid false-negative and false-positive results. With ACCURUN controls, you can troubleshoot your test methods and isolate system errors in your laboratory. Powerful ACCURUN controls and reference materials help to ensure complete control over assay performance monitoring. Challenges Your Assay More Effectively A low-positive control challenges your assay more than a medium-to-high control since it is closer to the assay cut-off; therefore, any variability in the assay will be easier to detect. Assay monitoring with ACCURUN single and multi-analyte controls improves confidence in your serology test results.
