bioavid Lateral Flow Walnut
Art. No.: BL607-10 / BL607-25
The Lateral Flow Walnut assay is used for the qualitative detection of walnut residues in environmental / surface samples (e.g. in food production lines). The assay is also applicable for food samples. The assay is applied for the detection of small amounts of walnut contaminations.
Walnut contaminations in food possibly elicit hypersensitivity in sensitive persons. Food production lines have to be free of residues to prevent these allergic reactions. The effectiveness of cleaning can be verified by using the Lateral Flow Walnut Swabbing method.
Dip sticks are an easy to use method and provide a fast and reliable analysis. The application of our bioavid dip sticks is very simple and can be handled by untrained personell. All bioavid test kits can be stored at room temperature and therefore they are an ideal tool for direct testing in production facilities. The bioavid test kits contain the complete equipment for the analysis.
Highly colored or acidic / alkaline solutions have to be extracted with the Absorbent buffer (BS810-25). The buffer decolors or neutralizes solutions to avoid false positive results (e.g. highly colored juices).
For the analysis of non-validated samples, the document “SOP Verification Solid Sample Test” (standard operation procedure) and a detailed instruction for use can be used.
