Cryotechnology is the foundation of modern biological research. Without the ability to preserve living cells, tissues, and genetic material at ultra-low temperatures, biobanks, stem cell research, IVF, and cellular therapies would not exist. Liquid nitrogen at –196°C is the only medium that reliably maintains biological viability over decades.
This pillar post provides a complete overview of cryotechnology in life science — from physical principles through equipment types to planning a turnkey biobank.
Cryotechnology refers to all methods and technologies for preserving biological materials through deep cooling. The term derives from the Greek kryos (cold, frost).
In life science, cryotechnology encompasses:
The boiling point of liquid nitrogen at atmospheric pressure is –196°C. At this temperature, all biochemical and biological processes stop completely. Enzymatic reactions, lipid oxidation, DNA damage from free radicals — all cease.
This makes –196°C the only temperature at which true long-term biological preservation is possible. Electric deep freezers at –80°C (ULT freezers) slow biochemical processes without stopping them. For applications requiring more than five years of storage, –80°C is insufficient.
Oocytes, sperm, and embryos are cryopreserved to allow multiple transfer attempts from a single stimulation cycle. Cryotechnology is the foundation of modern reproductive medicine.
Adult stem cells, iPSCs (induced pluripotent stem cells), and hematopoietic stem cells from cord blood require long-term storage for research and clinical applications. GMP-compliant cryosystems are mandatory in this domain.
Active pharmaceutical ingredient intermediates, microbial production strains, cell line cultures — all require cryogenic storage for quality assurance and operational continuity.
Biobanks store samples — blood, tissue, DNA, RNA, serum — for long-term studies. Qualified cryotechnology under ISO 20387 is a prerequisite for the scientific usability of samples.
Cord blood contains hematopoietic stem cells. Public and private cord blood banks store it long-term for potential transplantation use.
The first and most critical step in cryopreservation is the freezing process itself. An uncontrolled freeze produces dramatically lower survival rates than a programmed, controlled-rate protocol.
The BIOFREEZE® from Consarctic® is the standard for professional cryopreservation. Its TC-Aktiv function detects crystallization heat and automatically triggers a compensatory cooling impulse — reproducible protocols, maximized survival rates, complete GMP documentation.
Cryogenic tanks maintain samples at –196°C. The choice between aluminum (ABV+ Series) and stainless steel (ABS+, BSD+, BSF+) depends on capacity, intended use, and application area.
The BSD+ Series from Consarctic® holds up to 100,000 cryovials, optimized for biobanks and pharmaceutical long-term storage. The BSF+ Series accommodates up to 1,700 bags of 500 ml — the solution for cellular therapies and hematopoietic stem cell banks.
The ASR+ Series from Consarctic® enables cryogenic sample transport without free liquid nitrogen — IATA-compliant, with integrated data loggers for continuous temperature documentation during transit.
The Consarctic® Monitoring-System tracks LN₂ levels and temperatures for all tanks continuously. Remote alarm, app notification, continuous data logging. For GMP-regulated facilities, monitoring is an integral component of qualification documentation.
Building a biobank is an infrastructure project, not just equipment procurement. Room planning, LN₂ supply, ventilation (LN₂ evaporates to gaseous N₂ — oxygen displacement must be addressed), fire suppression systems, access control, IT integration for sample management.
Consarctic® supports this process from initial planning through fully IQ/OQ-validated commissioning. Reference customers include:
Pharmaceutical and clinical facilities operate under strict GMP requirements. For cryogenic systems, this means:
Consarctic® delivers all components with necessary documentation and performs IQ/OQ qualification through certified technicians.
Cryotechnology refers to all technologies and methods for preserving biological materials through deep cooling. In life science, this includes cryopreservation (the freezing process), cryogenic storage (long-term preservation), cryogenic transport, and the complete supporting infrastructure.
Cryopreservation is the active freezing process — samples are brought to –196°C under controlled conditions. Cryogenic storage refers to the subsequent long-term preservation at –196°C. Both require different equipment: controlled rate freezers (e.g., BIOFREEZE®) for preservation; cryogenic tanks for storage.
Theoretically indefinitely. Studies show no significant biological quality decline over decades of correct cryogenic storage. The limiting factors are practical — sample accessibility, documentation management — not biological.
Costs depend on scale, capacity, site requirements, and regulatory environment. Consarctic® provides budget planning support and turnkey projects for facilities of every size — from small research units to national biobanks.
ISO 20387 is the international standard for biobanking. It defines requirements for competence, quality assurance, and sample integrity. Facilities building and operating scientifically usable sample collections need this certification — or equivalent internal standards aligned to its requirements.
Cryotechnology is not laboratory equipment. It is core infrastructure for every biological research and clinical application requiring long-term sample integrity. The decision about the right cryogenic infrastructure — instruments, systems, service partner — is a strategic decision with consequences spanning twenty years of operation.
Consarctic GmbH is the partner for that decision. Serving 1,500+ customers in 30+ countries, with certified technicians and 24/7 support worldwide.
