15 ml Polypropylene Centrifuge Tubes Key benefits Leak reduction and secure storage: Longthread screw cap with an integrated sealing ring creates a tight closure to minimize sample leakage during handling and shortterm transport. Easy labeling and tracking: A dedicated white area on each tube provides a clear surface for handwriting or labels, making sample identification fast and reliable. Improved sample recovery: Smooth, flat inner surfaces prevent liquid from clinging to corners or seams, helping to recover nearly all of the sample and reducing waste. Chemicalresistant and durable: Made from quality polypropylene for routine laboratory use and reliable performance over multiple handling steps. What this product solves Prevents spills and crosscontamination with a secure screw cap and sealing ring. Simplifies sample management with an easytomark white labeling area. Reduces sample loss during transfers and centrifugation because fluids do not adhere to the tube interior. Important attributes Capacity: 15 ml nominal volume. Material: quality polypropylene. Closure: Longlength screw cap with sealing ring for improved leak resistance. Labeling: Builtin white marking area for fast identification. Interior: Smooth, flat inner surface to minimize residual volume. Typical applications Centrifugation and separation of biological samples in biochemistry and molecular biology workflows. Preparation and shortterm storage of reagents, isolated nucleic acids, or protein samples prior to downstream analysis. Routine spindowns, sample transfers, and temporary transport between workstations where secure closure and easy identification are required. Performance notes Designed for routine laboratory use where leakresistant closure, clear labeling, and efficient sample recovery are priorities. Handle and store according to your laboratory's protocols for temperature and chemical compatibility.
