Froilabo Voyager Series Stainless Steel Liquid Nitrogen Cryogenic Storage Tank

Overview

The Froilabo Voyager Series is a high-integrity stainless steel liquid nitrogen (LN₂) cryogenic storage system engineered for mission-critical biological sample preservation in regulated life science environments. Utilizing a double-walled vacuum-insulated architecture with multi-layer reflective shielding and optimized neck geometry, the Voyager tank achieves exceptionally low boil-off rates—typically <0.8 L/day for mid-size models—without compromising accessibility or thermal stability. Its dual-phase storage capability enables flexible configuration: samples may be held either submerged in liquid phase (−196 °C) for maximum thermal uniformity or suspended in vapor phase (−150 °C to −190 °C), minimizing cross-contamination risk while maintaining viability for sensitive cell types including hematopoietic stem cells, oocytes, and primary tissue isolates. Designed and manufactured in France under strict quality control protocols, the Voyager series aligns with foundational requirements for biobanking infrastructure as outlined in ISO 20387:2018 (Biobanking — General requirements for biobank operations) and supports audit readiness for GLP, GCP, and GMP-aligned workflows.

Key Features

• Medical-grade 304 and 316 stainless steel construction ensures corrosion resistance, non-pyrogenicity, and compatibility with repeated decontamination cycles using ethanol, hydrogen peroxide vapor (HPV), or validated sterilants.
• Wide-mouth opening (≥120 mm diameter) facilitates rapid, ergonomic handling of racks, canes, and automated retrieval modules—critical for high-throughput biorepositories and clinical labs processing >500 samples daily.
• CryoMemo intelligent monitoring system provides real-time display of LN₂ level, internal temperature gradients (vapor phase profiling), door open duration, and historical consumption trends; data logging is timestamped and exportable via USB or optional Ethernet interface.
• Passive anti-fog mechanism activates upon lid removal, directing dry nitrogen flow across optical surfaces to prevent condensation on viewing windows and internal camera systems—enabling uninterrupted visual inventory verification.
• Modular rack support accommodates industry-standard formats: 10×10, 8×8, or 6×6 configurations for 2 mL cryovials; compatible with barcode-labeled aluminum or polypropylene canes meeting ANSI/SLAS standards.
• Structural integrity verified per EN 13445-3 (Unfired pressure vessels) and ASME BPVC Section VIII Division 1 for vacuum-jacketed cryogenic containers.

Sample Compatibility & Compliance

The Voyager series supports long-term storage of diverse biospecimens—including peripheral blood mononuclear cells (PBMCs), induced pluripotent stem cells (iPSCs), semen, embryos, and genomic DNA extracts—under conditions that preserve nucleic acid integrity, membrane fluidity, and metabolic quiescence. All models are supplied with CE marking under the EU Medical Device Regulation (MDR 2017/745) Annex XVI for ancillary storage devices used in diagnostic and therapeutic applications. The CryoMemo system’s audit trail functionality satisfies FDA 21 CFR Part 11 requirements for electronic records and signatures when configured with user authentication and event-locked data export. Documentation packages include IQ/OQ templates, material traceability certificates, and vacuum decay test reports.

Software & Data Management

CryoMemo firmware v3.2+ delivers secure, role-based access control (administrator/operator modes), configurable alarm thresholds (e.g., LN₂ level −140 °C), and automated email/SMS notifications via integrated GSM or LAN modules. Raw sensor data is stored locally for ≥12 months and synchronized to networked servers using TLS 1.2–encrypted FTPS or MQTT protocols. Export formats include CSV (for LIMS integration), PDF summary reports (compliant with ISO/IEC 17025 documentation guidelines), and JSON payloads compatible with enterprise biobank management platforms such as OpenSpecimen and caTissue.

Applications

• Centralized biobanks operating under ISO 20387-accredited quality management systems
• Hematology and reproductive medicine units requiring traceable, temperature-stable storage for cord blood units and cryopreserved spermatozoa
• Pharmaceutical clinical trial sample repositories managing longitudinal cohorts across multiple geographies
• Academic core facilities supporting CRISPR-edited cell line archiving and organoid biobanking initiatives
• Public health laboratories maintaining reference strain collections for infectious disease surveillance (e.g., WHO collaborating centers)

FAQ

Does the Voyager series support integration with laboratory information management systems (LIMS)?

Yes—via standardized CSV exports, RESTful API endpoints (available under extended support contract), and native drivers for Thermo Fisher SampleManager and LabVantage platforms.
What is the recommended maintenance schedule for vacuum integrity verification?

Annual vacuum decay testing is advised; Froilabo provides certified field service technicians and calibrated gauges compliant with ISO 10428 for on-site validation.
Can vapor-phase temperature uniformity be mapped across the entire storage chamber?

Yes—optional thermal mapping kits (with 12-channel NIST-traceable thermocouples) enable ISO 14644-3-compliant spatial profiling during qualification and requalification cycles.
Is remote monitoring available without on-premise server infrastructure?

Cloud-hosted CryoMemo Connect service offers secure browser-based dashboards with customizable SLA-backed uptime (99.95%) and HIPAA-compliant data residency options in EU/US/APAC regions.
