Premium 15 mL and 50 mL conical tubes manufactured from high-clarity polypropylene. Features dark imprinted graduations and a large white writing area for sample identification. Flat polyethylene cap also provides another opportunity for labeling. Available in sterile bulk and racked versions (50 mL self standing bulk only); the racks are made out of reusable cardboard, making them more environmentally friendly. The inner packaging is individually labeled for lot-to-lot traceability with ‘easy-tear’ opening. Fine production tolerances enable high RCF ratings. Sturdy cardboard outer boxes provide additional transport protection. All styles in cases of 500 tubes.
