United Scientific® 15mL Sterile Centrifuge Tubes, Conical Bottom, PP/HDPE with Screw Caps, Pack of 500

{ "44261952946312": { "extra_description": "Designed for accuracy and reliability in laboratory workflows, United Scientific® 15mL Sterile Centrifuge Tubes are made of durable polypropylene with leak-proof blue HDPE screw caps. Each conical-bottom tube features smooth hydrophobic walls to reduce sample adhesion, silk-screen graduations for precise measurements, and a frosted writing surface for easy labeling. Autoclavable at 121°C, DNase-, RNase-, and pyrogen-free, these tubes ensure contamination-free use. Sterilized by gamma radiation, they are suitable for high-speed centrifugation up to 18,000 RCF. Ideal for academic, research, and clinical laboratories." }, "44261952979080": { "extra_description": "United Scientific® 50mL Sterile Centrifuge Tubes provide dependable performance for sample preparation and storage. Manufactured from high-quality polypropylene, each tube includes a blue HDPE screw cap with a vacuum-type leak-proof closure. Featuring hydrophobic interiors that prevent sample loss, clear silk-screen graduations, and a frosted writing area, these conical-bottom tubes ensure precision and convenience. With a maximum RCF of 20,000, they are built for high-speed centrifugation. Autoclavable, gamma-sterilized, DNase-, RNase-, and pyrogen-free, these tubes meet the demands of research, clinical, and educational labs." }, "44261953011848": { "extra_description": "United Scientific® 15mL Amber Sterile Centrifuge Tubes are specifically designed for light-sensitive samples. The amber polypropylene construction effectively blocks light to protect sensitive compounds, making them ideal for molecular biology, microbiology, and biochemistry applications. Each tube features a leak-proof HDPE screw cap, smooth hydrophobic interior for minimal sample retention, silk-screen graduations for accuracy, and a frosted writing surface.
