Froilabo VSHIPPER Series Aluminum Liquid Nitrogen Shipping Dewar

Overview

The Froilabo VSHIPPER Series is a purpose-engineered aluminum liquid nitrogen shipping dewar designed for the reliable, compliant, and thermally efficient transport of temperature-sensitive biological specimens. Unlike conventional stainless steel or fiberglass dewars, the VSHIPPER leverages a high-strength, low-density aerospace-grade aluminum alloy monocoque construction—optimized for thermal inertia, mechanical resilience, and weight reduction without compromising structural integrity under vibration or thermal cycling. Its operational principle relies on passive vacuum insulation combined with a proprietary porous cryo-absorbent liner system that actively manages nitrogen phase change dynamics: during lid opening, the liner temporarily absorbs and retains vaporized nitrogen, minimizing transient boil-off and preserving internal temperature stability (−196 °C) for up to 60 seconds of repeated sample access. This architecture enables consistent ultra-low-temperature maintenance across variable ambient conditions (−20 °C to +40 °C), fulfilling critical requirements for viable cell transport, stem cell logistics, and reproductive tissue shipment.

Key Features

• Aerospace-grade aluminum alloy body: Provides superior strength-to-weight ratio (≈40% lighter than equivalent stainless steel dewars), facilitating manual handling and reducing air freight surcharges.
• Multi-layer vacuum-insulated neck and sidewall: Achieves thermal conductivity <0.15 W/m·K at −196 °C, extending static hold time to ≥10 days when filled to nominal capacity (per ISO 23771:2021 test protocol).
• Patented porous cryo-absorbent liner: Chemically inert, non-fibrous cellulose-silica composite that captures and re-condenses nitrogen vapor upon lid closure—reducing net LN₂ loss by up to 35% during frequent access cycles.
• IATA PI 650-certified design: Integrated pressure-relief venting, impact-resistant outer shell, and leak-tested inner vessel meet all regulatory criteria for Category B biological substance transport by commercial aviation.
• Ergonomic top-loading configuration with dual-seal lid: Ensures rapid, glove-compatible sample insertion/extraction while maintaining vapor-phase temperature uniformity across canister racks (±0.5 °C over 90% volume).

Sample Compatibility & Compliance

The VSHIPPER accommodates standard cryogenic storage formats including 1.2 mL, 2.0 mL, and 5.0 mL external-thread vials; 25 × 125 mm cryotubes; and programmable-rate freezing boxes (up to 10 × 10 configuration). Internally, it supports both vapor-phase (−150 °C to −190 °C) and liquid-phase (−196 °C) storage modes, with optional aluminum canister inserts enabling ISO/IEC 17025-compliant traceability via laser-etched serial numbering. Regulatory alignment includes full documentation for FDA 21 CFR Part 11 audit trails (when paired with Froilabo’s optional CryoLog™ data logger), adherence to EN 13485:2016 for medical device transport, and compatibility with GLP/GMP cold chain validation protocols per WHO TRS 961 Annex 9.

Software & Data Management

While the base VSHIPPER operates as a passive transport system, integration with Froilabo’s CryoLog™ Wireless Monitoring System (sold separately) enables continuous, cloud-synced logging of core environmental parameters: internal vapor-phase temperature (±0.25 °C accuracy), ambient temperature, barometric pressure, and lid-open event timestamps. Data is encrypted (AES-256), stored in ISO 27001-certified infrastructure, and exportable in CSV or PDF report format compliant with FDA 21 CFR Part 11 electronic record requirements—including user authentication, audit trail generation, and electronic signature capability. All firmware updates are delivered via secure OTA protocol with SHA-256 signature verification.

Applications

• Clinical biobanking: Transport of PBMCs, isolated T-cells, and CAR-T constructs between collection sites and central processing laboratories.
• Assisted reproductive technology (ART): Safe inter-facility transfer of oocytes, embryos, and spermatozoa under sustained ≤−150 °C vapor-phase conditions.
• Pharmaceutical cold chain: Distribution of viral vectors, mRNA-LNPs, and other thermolabile biologics requiring uninterrupted cryogenic integrity.
• Academic research logistics: Cross-institutional sharing of genetically engineered mouse models (GEMMs), organoids, and primary neuronal cultures.
• Emergency response: Rapid deployment of cryopreserved antidotes, antivenoms, or diagnostic reference standards during public health incidents.

FAQ

Is the VSHIPPER suitable for long-term storage, or is it strictly for transport?
The VSHIPPER is engineered and validated exclusively for short-to-medium duration transport (≤14 days). It is not certified or recommended for stationary long-term storage; dedicated stationary LN₂ freezers (e.g., Froilabo ULT series) must be used for archival preservation.
Does the VSHIPPER require dry ice or external power?
No. It operates entirely passively using liquid nitrogen as the sole cryogen—no electrical input, dry ice supplementation, or active cooling systems are needed.
Can the VSHIPPER be used for shipping infectious samples classified under UN 2814 or UN 2900?
Yes—provided it is configured with the optional IATA-compliant secondary containment kit (VSHIPPER-BIO), which includes leak-proof inner liner, absorbent pad, and triple-layer packaging meeting Packing Instruction 650 requirements.
What documentation accompanies each unit for regulatory submissions?
Each VSHIPPER ships with a Declaration of Conformity (DoC), IATA PI 650 test report, CE certificate, material composition dossier (EN 10204 3.1), and a completed U.S. DOT Special Permit application template for domestic air transport approval.
