CELLTREAT® Metal Free Centrifuge Tubes, 50 mL, Graduated, Polypropylene, Sterile, 500/Case

Durable centrifuge tubes are validated to contain less than 1 part per billion (ppb) of more than 30 trace metal elements, ensuring that samples are free of contaminants. Each tube features clearly printed graduations at every 2.5 mL increment for easy visibility, with an accuracy of ±2%. A large white marking area provides excellent contrast for easy identification. Additionally, the tubes have graduations molded into the conical bottom, which are ideal for observing pellets and quantifying small volumes.

Each tube comes with easy-to-write-on polyethylene (HDPE) caps that feature an integrated leak-proof seal. These centrifuge tubes are rated for a maximum relative centrifugal force (RCF) of 16,000 g. Tubes are packaged in a convenient zip-closure bag, offering a practical alternative to folding and taping open bags. 25 tubes/bag; 20 bags/case.
