What Are CBS High Security Sperm Straws?

CHICHESTER, U.K. - Aug. 1, 2025 - PRLog -- CBS High Security sperm straws are advanced cryopreservation containers designed for the safe, long-term storage of sperm and embryos in liquid nitrogen. Used in assisted reproductive technology (ART) labs around the world, these straws are trusted for their durability, sterility, and leak-proof performance.

Unlike standard cryo straws, CBS High Security straws are built to eliminate the risk of cross-contamination during storage. Each straw is hermetically sealed, meaning no exchange of liquid or vapor can occur between the sample and its external environment—critical for protecting sample integrity over time.
