Sanicult™ Sterile Neutralizing Buffer Swab System (Starplex Scientific)
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 neutralizing buffer solution. Swab is non-toxic rayon attached to a 3 1/2” plastic stem, which is secured to the tube cap. Buffered peptone water contains two neutralizers to inhibit false-negative results of several sanitizing chemical residues: lecithin and polysorbate 80 (Tween® 80).
