Cryo vials are normally used for storage of biological material, human & animal cells. These sterilized tubes are provided with white, prominent graduations and a long marking area for sample identification. The cap of these vials is provided with a seal ring inside to make it completely leak proof. The longitudinal grooves in the base give a non twisting feature to these vials when placed in a cryo rack.
