Thermo Scientific* Nalgene Cryogenic Tubes are externally threaded storage tubes ideally suited for research and general laboratory storage of high value and genomic materials down to vapor phase liquid nitrogen temperatures.

• Large writing areas accommodate more written sample information and graduations for easy visual volume assessment
• Non-cytotoxic raw materials for added sample security and tubes certified free of Dnase and RNase for genomic applications
• External threading enhances aseptic technique
• Certified SAL of 10-6 for the highest sterility assurance available
• Suitable for storage from general cold storage refrigeration （+4°C） down to the vapor phase of liquid nitrogen
• System 100 Tubes offer a more dense storage option （10x10） to save precious storage space
• Self standing tubes for ease of use on the benchtop
• Blank, non-sterile and uncapped tubes available in bulk for less demanding applications
• Certifications: CE Marked for storage of diagnostic samples in the EU
