15 mL Conical Centrifuge Tube, Polypropylene, Graduated, No Cap

Reliable tube geometry for everyday laboratory centrifugation and sample handling. The 15 mL Conical Centrifuge Tube is a standard-format polypropylene conical tube designed for use across cell biology, microbiology, chemistry, and clinical research workflows. Available in a 1,000-piece set (2 boxes of 500 pcs each), these tubes are suited for labs, research facilities, educational institutions, and diagnostic centers that require consistent performance and bulk availability.

Graduated for Visual Volume Reference

Each tube features printed graduation marks from 1 to 14 mL in 1 mL increments along the cylindrical body, providing a quick, at-a-glance volume reference during sample loading and preparation without requiring a separate graduated cylinder or pipette for basic estimation.

Polypropylene Construction,  Clear & Chemically Compatible

Fabricated from polypropylene (PP), each tube offers good resistance to a broad range of aqueous buffers, biological media, saline solutions, and standard laboratory reagents. The clear transparent wall enables direct visual inspection of sample volume, color, clarity, and pellet formation during and after centrifugation without opening the tube.

Conical Bottom, Efficient Pellet Recovery

The conical bottom taper is designed to concentrate pelleted material into a compact focal point during spin cycles, facilitating clean decanting and complete sample recovery. Sold without cap, tubes are compatible with standard 17 mm screw caps (sold separately), allowing users to select the cap type appropriate for their sealing and storage requirements.
