Use the SwabCheck sterile cellulose swabs to quickly and easily check for the presence of bacteria on a surface. Simply wipe a surface with a swab, insert the swab into a tube containing a special medium with an indicator dye for a specific microorganism, then incubate. The super-sensitive SwabCheck medium changes color even when only a single bacterium is present. The quicker the color change happens, the higher the number of bacteria that are present. No color change after the maximum incubation period indicates the absence of the corresponding microorganism.

The hygiene SwabCheck swabs help monitor the levels of contamination at work areas and production lines to ensure they meet the requirements for cleanliness. This rapid, same-day hygiene test changes color from red to yellow when gross bacterial and fungal contamination is detected; faster the change, higher the concentration. Use the hygiene SwabCheck swabs in conjunction with known specification levels for a more accurate assessment. Store swabs and gel media in temperatures between 5 and 25°C (41 and 77°F).
