Sterile Neutralizing Buffer Swab System (Copan)
A useful portable swab system for the microbiological sampling of equipment and containers. Individually wrapped screw-cap plastic tubes come pre-filled with 10 mL of a sterile neutralizing buffer solution and a sterile 6” non-toxic rayon swab. Buffered rinse solution contains neutralizers to inhibit false-negative results of most sanitizing chemical residues, see specifications below.
