Designed with a new kind of premium polymer material with superior frost/aging resistance, which is specially developed by NEST, is applied and saves from foreign contamination. Its can withstand temperatures ranging from -196℃ to 121℃, and is autoclavable. No cracking nor leakage occur amid the repeated freeze-thaw cycles of -196℃, -80℃ and 100℃ .
ScrewCap is Compatible with Automatic Decapper
The special injection molded pattern on the cap can perfectly match the majority of the automatic decappers, hence saves many manual operation processes and eliminates the contamination risk, making cryo-preservation process easier, safer and faster.
