CleanTrace™ ALLTEC60 Surface Protein Swabs are a fast and easy way to visually check whether cleaning has been carried out to a satisfactory standard by means of protein detection. By comparing the color of the swab and solution against the label, the user can easily interpret the results for the presence of allergens. Clean-Trace® ALTEC60 Surface Protein (Allergen) Test Swab is validated for a range of allergenic proteins, including egg, milk, gluten, soy, peanut, almond and buckwheat. Refrigeration is not required -swabs can be stored at room temperature (25°C or 77°F). This easy-to-use device requires minimal training. The results are semi-quantitative with four possible color interpretations. The faster the test turns purple and the stronger the color change the higher the level of contamination on a surface Quick detection and confirmation allows immediate corrective action to take place. A visual reading of a color change indicates the level of cleanliness by detecting as little as 3µg of allergen on surfaces and in solution. No instrumentation is required to interpret the sample results. This product is easily integrated into company HACCP programs to monitor for cleaning effectiveness. Its ease of use, reliable detection and fast, visible results can help in teaching staff the importance of cleaning.
