A disposable swab for oral and nasopharyngeal sampling
Date:2019-03-06    Source:
Nasopharyngeal sampling swab is composed of nylon staple fiber villus and medical grade ABS plastic rod. Nylon staple fibers act like a soft brush, which can effectively improve the collection of cell materials; the capillary movement between the fibers forms a strong hydraulic pressure to absorb liquid samples; at the same time, the samples are close to the surface of the swab and easy to elute.
