A porous molded plastic swab construction for microbiological or other use including a swab element attached to an elongated carrier member. The swab is constructed from molded porous plastic materials such as high density polyethylene, ultra-high molecular weight polyethylene, polypropylene, polyvinyledene fluoride, ethylene-vinyl acetate, styrene-acrylonitrile, polytetrafluoroethylene and silicone rubber having a pore size of from about 10 to about 2,000 microns with a density of about 35% to about 60% void volume. The swabs are designed for incorporation into specimen collection instruments, or for individual use as collectors or applicators. |
