Celltreat's new Sure Cap centrifuge tubes feature caps with compressible liners to create a stable seal. They are constructed of medical grade virgin polypropylene and have smooth, flat-surface HDPE caps. Graduations are printed in bold, easy-to-read black ink and are accurate to ±2%. The large white marking area provides excellent contrast for identification.
Tubes have a temperature range of -80°C to 120°C and are provided sterile (gamma irradiated) in zip-closure bags.
