What Are CBS High Security Sperm Straws?



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.

CBS Embryo and Sperm Straws: 0.15ml, 0.3ml, 0.25ml, and 0.5ml Options for Cryopreservation

Cryopreservation is only as reliable as the containers used to store the biological material. CBS straws specifically designed for embryos, oocytes, and sperm offer a consistent, high-quality solution for long-term storage in liquid nitrogen.

CBS Embryo Straws – 0.15ml and 0.3ml

CBS embryo straws are thin-walled, medical-grade plastic tubes engineered for safely freezing and storing embryos, oocytes, or sperm. Available in 0.15ml and 0.3ml capacities, they give embryologists and lab technicians options for handling different sample volumes without compromising traceability or safety.

  • Material: Medical-grade plastic
  • Sizes: 0.15ml and 0.3ml
  • Use: Embryos, oocytes, or sperm
  • Storage: Ultra-low temperatures in liquid nitrogen
  • Features: Precise volume control, compatibility with standard cryo storage systems

These straws are widely used in IVF clinics, fertility labs, and research institutions where reliability and sterility are non-negotiable.

PETG Sperm Straws – 0.25ml and 0.5ml

For sperm cryopreservation, classical PETG (polyethylene terephthalate glycol) straws provide another dependable option. These are clear, sterile straws designed for use in long-term sperm storage, with sizes suited for different sample requirements.

  • Material: PETG – strong, clear, and biologically inert
  • Sizes: 0.25ml and 0.5ml
  • Use: Sperm cryopreservation
  • Sterility: Supplied sterile
  • Durability: Designed to withstand ultra-cold storage in liquid nitrogen without cracking or compromising the sample

These PETG straws offer both visibility for inspection and strength for safety. Their clarity makes loading and identification easier, while their durability ensures confidence in storage and transport.

Why Clinics Trust Them

The combination of high-quality materials and airtight sealing makes CBS High Security straws especially valuable for fertility clinics, sperm banks, and research labs where sample security isn’t optional. They meet international standards for biostorage and have been validated across thousands of procedures worldwide. Visit www.cryolab.co.uk for more information.
