Loops and needles are smooth and flexible to facilitate uniform streaking without damaging the gel surface. Needles are straight and suitable for removal of specimens of single colonies. Packed sterile in safe, tamperproof, zip-lock resealable bags. Disposable inoculating loops and needles do not require flaming and thus eliminate the risk of infection due to aerosol formation of pathogenic substances. Cross contamination due to improper sterilization is eliminated. They can be used under hoods without danger, and are color-coded for ease of size identification. Certificate of conformity available upon request.
