Our 50ml polypropylene conical centrifuge tubes are perfect for everyday lab work and manufactured from medical-grade virgin polypropylene conforming to USP Class VI for chemical resistance. Every centrifuge tube comes with a leak-proof cap and a large white writing surface for easy to read labeling. Dark blue graduations are calibrated and printed every 0.5 and 1.0ml.
Our new polypropylene rack is green initiative compliant, reusable, recyclable and has a lower environmental impact compared to Styrofoam.
