Guide and selection support
Cryo storage is used to keep biological samples viable over long periods at temperatures far below freezing. Liquid nitrogen is primarily employed to preserve cell structures and tissues almost indefinitely. Suitable applications are found in molecular biology, cell culture, and medical research. When selecting cryo storage solutions, critical factors include temperature range, storage capacity, and compatibility with biological materials. Safe handling and options for documenting storage conditions are also important. Consumables for cryopreservation complete the range of system options. LabFinder supports users in this specialized product category with a clear overview of relevant solutions and specific search terms, helping them to quickly find suitable cryo storage systems and accessories without distraction from unrelated products.
Applications and Benefits
Cryo storage is used to store biological samples at temperatures below -140 °C in liquid nitrogen. This method enables the cryopreservation of cells, tissues, and other biological materials with the aim of maintaining their viability and functionality over long periods. Cryo storage is applied in fields such as cell culture, molecular biology, medical research, and biobanking. Typical samples include blood cells, sperm, oocytes, embryos, and plant cells.
Selection Criteria
The choice of the appropriate cryo storage system depends on several factors: The storage temperature should consistently remain below -140 °C to minimize cell damage during freezing and thawing. Storage capacity must match sample quantities, as must compatibility with the containers used. Practical requirements such as easy sample retrieval, safe handling of cryo containers, and clear storage organization are also important. Consumables for cryopreservation are often selected separately.
Variants and Technical Aspects
Cryo storage systems are primarily based on the storage of samples in liquid nitrogen, either in open or closed containers (cryotanks). Variants differ in terms of capacity, insulation materials, and supporting equipment, such as sample racks or tracking systems. The systems enable stable ultra-low temperature storage, which conventional freezers cannot achieve. In addition, consumables such as cryovials are tailored to these storage conditions.
Calibration and Maintenance
Maintenance includes regular monitoring of liquid nitrogen levels to ensure storage temperatures. Monitoring and documentation of temperature and storage conditions are important and usually require separate measurement technology. Cleaning of cryotanks and safe handling of hazardous materials such as liquid nitrogen must follow standard safety regulations. Classic calibration routines are not typical for storage vessels, but temperature monitoring systems should be regularly checked.
Limitations of Use
Cryo storage is not suitable for all sample types; certain materials may suffer structural damage from freezing. Handling also requires experience and suitable protective measures when working with extremely low temperatures. Storage is cost-intensive and requires appropriate infrastructure. The storage duration must also be limited by the stability of the samples at the intended temperature.

Frequently asked questions
How does cryo storage of biological samples work?
Cryo storage preserves biological samples by freezing them at temperatures below -140 °C and storing them in liquid nitrogen. This prevents cell damage and maintains viability over long periods.
What types of samples can be stored using cryo storage?
Typical samples include animal and plant cells, tissues, blood, sperm, oocytes, and embryos. Cryo storage is suitable for biological materials whose structure should be preserved by deep freezing.
What should I consider when selecting a cryo storage system?
Essential criteria include the temperature range (below -140 °C), capacity, compatibility with sample containers, user-friendly handling of cryo vessels, as well as options for temperature monitoring and documentation.
What maintenance measures are needed for cryo storage systems?
Regular checks and refilling of liquid nitrogen, cleaning of storage containers, and monitoring of storage temperatures are essential. The storage systems themselves do not require calibration, but temperature measurement equipment should be inspected.
What are the limitations of cryo storage in practice?
Not all samples are suitable for freezing, as some materials may incur damage. Handling liquid nitrogen requires appropriate safety measures and infrastructure. Storage costs and experience in handling are additional factors.
