Micro Centrifuge tubes are manufactured using high purity virgin Polypropylene (PP) conforming to US FDA 21 CFR standard of being free of rubber and heavy metals. Along with the integral snap cap, these boil-proof tubes can be used at -80°C and are inert with various organic solvents. These tubes can withstand up to 20000 RCF (Relative Centrifugal Force) or G-Force.
- Frosting on the surface of the tubes allows for ease of labeling/writing
- Large molded in graduations make identification easy
