DH-2019 portable rapid hair grinder adopts a special "8" shaped three-dimensional oscillation mode. By the high-frequency reciprocating vibration, impact, and shearing of the grinding beads (zirconia, steel, glass, ceramics), it is suitable not only for fine crushing and grinding of hard, medium-hard, and brittle samples, but also for soft, elastic, fibrous materials, etc. The rapid achievement of ideal grinding effects makes the sample more fully and uniformly ground, with better sample repeatability and no cross-contamination between samples. After grinding, in combination with colloidal gold detection technology, it can be used for rapid on-site detection of common drugs in hair (such as heroin, methamphetamine, ketamine, ecstasy, marijuana, etc.). The detection limits for various drugs have reached the requirements of the "Technical Specification for Hair Sample Detection of Drug-Related Personnel" issued by the Ministry of Public Security. Since its launch, the product has been widely recognized in the industry. The hair on-site detection device has the advantages of simple sample processing, convenient carrying, efficient detection, accurate results, and high sensitivity, making it an ideal equipment for law enforcement personnel in public security and anti-drug work to perform on-site hair drug testing. |
