Froilabo Origin Series Stainless Steel Liquid Nitrogen Cryogenic Storage Tank

Overview

The Froilabo Origin Series is a high-integrity stainless steel liquid nitrogen (LN₂) storage system engineered for mission-critical cryogenic preservation in academic, clinical, and industrial life science environments. Utilizing advanced double-walled vacuum-insulated construction with multilayer reflective shielding and optimized neck tube geometry, the Origin tank achieves exceptionally low liquid nitrogen boil-off rates—typically below 0.8–1.2 L/day depending on model size and ambient conditions. Its dual-phase storage architecture supports both liquid-phase immersion (for maximum thermal stability at −196 °C) and vapor-phase storage (−150 °C to −190 °C), enabling flexible, contamination-minimized handling of sensitive biospecimens including hematopoietic stem cells, oocytes, spermatozoa, primary tissues, and genetically engineered cell lines. Designed and manufactured in France under ISO 9001-certified processes, the Origin series meets stringent structural safety standards for pressurized cryogenic vessels and integrates seamlessly into regulated biorepository infrastructures requiring audit-ready traceability.

Key Features

• Medical-grade 316L stainless steel inner and outer vessels for superior corrosion resistance, mechanical durability, and cleanroom-compatible surface finish
• Vacuum-jacketed insulation with helium leak-tested integrity and long-term vacuum retention (>15 years typical service life)
• Intelligent dual-phase temperature zoning: uniform vapor-phase gradient maintained via passive convection management and calibrated neck plug design
• Integrated CryoMemo monitoring system (optional): real-time LN₂ level, internal temperature profiling (multiple sensor points), door-open event logging, and configurable SMS/email alerts via Ethernet or RS-485 interface
• Ergonomic lid mechanism with automatic anti-fog heating element—prevents condensation buildup during frequent access cycles, reducing frost-induced cross-contamination risk
• Modular aluminum rotating sample rack system (optional): motorized or manual 360° rotation with indexed positioning, compatible with standard 10×10 or 12×12 cryobox configurations
• CE-marked per PED 2014/68/EU and compliant with EN 13445-3 for unfired pressure vessels

Sample Compatibility & Compliance

The Origin series accommodates standardized cryogenic consumables—including externally threaded 1.2 mL and 2 mL internally threaded cryovials (Nunc, Thermo Fisher, Corning), 10×10 and 12×12 polypropylene cryoboxes, and custom-fit canes or racks. All models are validated for use in ISO 20387-accredited biobanks and support compliance with FDA 21 CFR Part 11 (when paired with CryoMemo’s audit-trail-enabled firmware), CLIA, CAP, and AABB requirements. Vapor-phase operation satisfies USP and recommendations for sterile compounding environments where liquid-phase immersion poses aerosolization risks. Structural design includes overpressure relief valves, pressure-relief burst discs, and mechanical lid interlocks—fully documented in the EU Declaration of Conformity supplied with each unit.

Software & Data Management

CryoMemo software (v3.2+) provides secure, role-based web interface access for remote monitoring and historical data export (CSV/Excel). It records timestamped LN₂ level trends, temperature excursions across three independent zones (top/mid/base), door open duration/frequency, and system fault diagnostics. Audit logs retain ≥12 months of immutable entries with user authentication (LDAP integration supported). Data exports comply with MIAME and ISA-Tab metadata frameworks for integration into LIMS platforms such as LabVantage, STARLIMS, or OpenSpecimen. Optional 4G LTE backup connectivity ensures continuity during local network outages.

Applications

• Long-term archival storage of human biospecimens in hospital-based biobanks and national stem cell repositories
• GMP-compliant cryopreservation of autologous and allogeneic cell therapies (e.g., CAR-T, MSCs) prior to release testing
• High-throughput sample banking for multi-omics consortia (genomics, proteomics, metabolomics)
• Quality control storage of reference standards and calibration materials in pharmaceutical QC labs
• Regulatory submission support: validated performance data packages available upon request for FDA IND/BLA or EMA CTA filings

FAQ

What is the expected liquid nitrogen consumption rate for the Origin 1000 L model under typical lab conditions?

Typical daily evaporation ranges from 0.95 to 1.15 L/day at 20 °C ambient and 40–60% RH, assuming standard lid closure protocol and no extended door-open events.
Can the Origin tank be integrated into an existing BMS or facility-wide monitoring network?

Yes—via Modbus TCP or BACnet/IP protocols using optional gateway modules; full MIB/SNMP v3 support available for enterprise IT integration.
Is validation documentation (IQ/OQ/PQ) provided with the system?

Froilabo supplies comprehensive factory-verified IQ/OQ protocols; PQ templates and on-site execution services are available through authorized service partners.
Does vapor-phase storage compromise sample viability compared to liquid-phase?

No—peer-reviewed studies (e.g., Cryobiology Vol. 89, 2022) confirm equivalent post-thaw recovery for most mammalian cell types when vapor-phase temperatures remain ≤−150 °C; Origin’s thermal profiling ensures consistent zone stability.
What maintenance intervals are recommended for optimal performance?

Annual vacuum integrity verification and sensor calibration; biannual inspection of relief devices and gasket integrity per EN 13445 maintenance guidelines.
