McKesson Tube Closure Flanged Plug Cap Natural Polyethylene 177-118127C 1000 per Bag

Avoid spills and protect collected biomedical samples and specimens in the lab with McKesson flanged plug caps. They fit securely over most 12 millimeter test tubes as well as round cuvettes and centrifuge tubes. With a clear natural color, these tube closures work alongside other available colors for color-coding different types of samples. Attachment and detachment are quick and easy with an pair of flexible flanges that press against the tube's inner wall. When in place, these test tube caps form secure seals against leaks and exposure to pathogens and microorganisms. They also can help avoid sample contamination that could impact test results. Precision-molded, low-density polyethylene material makes the plugs easy to handle.
