Whatman™ 10498406 Swabchek™ Specimen Collection Swab Kit, ColiCheck with MUG Coliform (Pack of 25)

Swabchek™ ColiCheck coliform swabs with MUG. Escherichia coli and coliforms are used traditionally as indicator organisms for fecal contamination in water and other environmental samples. Detection of these organisms usually points to poor hygiene at some stage in the production process or pollution of water at source. The presence of coliforms is indicated by a color change from red to yellow. The more rapid the color change the higher the level of coliform bacteria. These swabs are used as an indication of hygiene on contact surfaces. A Swabchek™ swab changes color from purple to yellow. The color change is based on acid reaction with the indicator. The more rapid the color change, the higher the level of bacteria in the sample. If no color change has been observed after the maximum incubation period has elapsed, then the corresponding microorganism is not present. Swabchek™ specimen collection swabs are useful in determining the sanitation levels of preparation surfaces, filling ports, and processing areas in beverage and food processing plants, dairies, restaurants, and healthcare facilities. Ideal for qualitative and semi-qualitative hygiene control with rapid results and a 12-month shelf life. 25/Pack. Quality Control & Recommended Incubation Conditions: Positive Control: Escherichia coli (E. coli) (ATCC 25922) - Incubated at 35°C for 48 hours.
