Centrifuge Tube KJ307-2, Snap Cap (1.5 ml) (CAT#: STEM-BC-1616-ZJF)

The KJ307-2 centrifuge tube is a disposable laboratory consumable designed for sample preparation, separation, and storage by centrifugation. It is manufactured from virgin polypropylene (PP) or polystyrene (PS) using precision injection molding to produce a clear, smooth-walled tube with reliable dimensional accuracy. The tube features graduated volumetric markings that are either molded directly into the wall or printed onto the surface for accurate liquid level reading. A large flat writing area on the tube body provides space for sample labeling, and the design accommodates adhesive label application where required. The conical base geometry facilitates maximum pellet recovery after centrifugation, while the bottom also carries fine-scale molded graduation marks for small-volume measurement. The cap-available in screw, snap, or safety-lock configurations-provides a secure, leak-proof closure under centrifugal force. The tube is compatible with standard centrifuge buckets and adapters used in microcentrifuges and high-speed floor centrifuges. PP-grade tubes exhibit broad chemical compatibility with polar organic solvents, dilute acids, and dilute bases, making them suitable for a range of biological and biochemical applications. The product is manufactured in a controlled cleanroom environment using high-purity raw materials free from heavy metals and biological contaminants. Multiple packaging formats are available, including individual bags, bulk bags, rack-loaded configurations, and foam tray formats, to accommodate various workflow preferences.
