A visual inspection for foreign material analysis involves carefully examining cannabis products with the naked eye or using magnification tools such as microscopes or magnifying glasses. During this inspection, trained analysts look for any visible signs of physical contaminants, such as plant matter, insects, hairs, fibers, or other foreign objects. The process typically includes sorting through the sample, section by section, to ensure thorough coverage.

Analysts pay close attention to the color, shape, size, and texture of any potential contaminants, comparing them against known standards or reference materials. Any anomalies or suspicious findings are documented and may undergo further analysis or testing to confirm their identity and potential impact on product safety.

Visual inspection is an essential first step in foreign material analysis, providing initial insights into the cleanliness and integrity of cannabis products. While it may not detect microscopic contaminants, it serves as an important screening tool to identify visible impurities and ensure product quality and compliance with regulatory standards.

At Cannabis ChemLab, we conduct foreign material analysis to ensure the purity and safety of cannabis products. Using advanced training and expertise, our analysts meticulously inspect samples for any physical impurities or contaminants that may compromise product quality. Through visual examination and sophisticated analytical techniques, we identify and characterize foreign materials, such as plant matter, insects, hairs, fibers, or other unwanted substances. Our rigorous approach ensures that cannabis products meet stringent quality standards and regulatory requirements, providing peace of mind to consumers and industry stakeholders alike.


A dissection microscope magnifies objects for detailed observation. It has two eyepieces and adjustable magnification settings. Light from below illuminates the specimen, allowing for examination of surface and internal structures. It's commonly used in research and education for studying small objects or biological samples.
