MS-NF7801 is a Flocked Sampling Swab used for cell & virus specimen collection, it has been designed for flu testing and nasopharyngeal clinical diagnostics. It utilizes state of the art spray on technology that the flocking process by means of an electro-static charge perpendicularly attaches millions of nylon microfibers on the medical grade handle tip. It has been well recognized and adopted by the diagnostic test kit manufacturers who produce reagents in molecular genetics, forensics and clinical laboratories sectors. The perpendicular nylon fibers act like a soft brush, allowing the improved collection and release of both cellular and liquid samples. The difference between MS-NF7801 and MS-NF7802 is just the stick, we use mixed PP for MS-NF7801 so the stick is soft and flexible.
