Corning^® Conical Bottom Centrifuge Tubes feature easy-to-read, high-contrast black graduations and a large white marking spot. Available in 15 mL size in either clear polypropylene (PP) or polyethylene terephthalate (PET). Polypropylene tubes provide excellent chemical resistance and mechanical strength. They are strong, moderately rigid, and well-suited for most disposable centrifuge applications. Polyethylene terephthalate tubes offer excellent optical clarity for ease of measurement, observation and test recording. They are recommended for use in moderately demanding environments.

These tubes are available with two styles of polyethylene screw-top caps: the advanced CentriStar™ Cap and the original Plug Seal Cap. The CentriStar Cap has an easy-on/easy-off flat top and offers advanced ergonomics with its wider knurls and roll-over edge design for easier gripping. This leak-resistant design comes with a revolutionary plug feature that prevents seepage when used under recommended conditions. The plug seal cap is an original Corning design featuring a contoured plug for a tight, secure seal.

Non-pyrogenic and sterile, bulk packed in zip lock bags or foam rack packs.

Due to an inventory disruption the foam rack will be suspended temporarily until the manufacturing operation resumes. Some of the products will be bulk packaged instead of being held in the standard foam rack to accommodate this temporary suspension. Bubble wrap is being added to provide adequate protection to the product during transit.
