FAQ

Q1: What is the difference between internal and external cap cryo tubes?
A: Internal cap tubes offer a tighter seal and reduced risk of contamination, while external cap tubes are easier to open and close, especially when wearing gloves.

Q2: Can these cryo tubes be used in liquid nitrogen?
A: Yes, they are designed for cryogenic storage and withstand temperatures as low as -196℃ in the vapor phase of liquid nitrogen.

Q3: Are the tubes sterile and DNase/RNase-free?
A: Yes, all cryo tubes are EO sterilized, and free from DNase, RNase, and pyrogens, ensuring safe use in molecular biology and clinical applications.
