Overview
The Froilabo GT Series aluminum liquid nitrogen cryogenic storage tanks are engineered for long-term, ultra-low-temperature biological sample preservation at –196 °C. Utilizing high-purity aluminum alloy construction and vacuum-insulated double-walled architecture, these tanks deliver exceptional thermal efficiency and mechanical robustness in demanding laboratory, clinical, and agricultural environments. Unlike stainless steel alternatives, the aluminum body offers superior strength-to-weight ratio, corrosion resistance in humid or saline settings, and non-magnetic properties—critical for proximity to sensitive instrumentation such as MRI suites or electrophysiology workstations. The GT Series operates on passive cryogenic storage principles: liquid nitrogen (LN₂) is stored in the inner vessel, while the evacuated annular space between inner and outer walls minimizes conductive and convective heat transfer. This design ensures stable temperature uniformity across the storage chamber and supports uninterrupted sample integrity over extended static hold periods—up to 350 days without refilling under controlled ambient conditions (20 °C, 50% RH).
Key Features
- Lightweight yet durable aerospace-grade aluminum alloy construction—reducing handling fatigue and enabling safe manual transport within biosafety level 2 (BSL-2) facilities.
- Optimized neck tube geometry and low-heat-leak vapor-phase storage configuration, minimizing LN₂ boil-off and extending static hold time across the full capacity range (25–350 days).
- Ergonomic, wide-mouth opening (≥120 mm diameter) with integrated handle and anti-slip base—facilitating rapid, aseptic access to canes, racks, and 0.5 mL straws without compromising thermal stability.
- Modular internal basket system compatible with internationally standardized cryovial formats (e.g., Nunc™, Corning®, Thermo Scientific™), supporting both vapor-phase and liquid-phase storage configurations per ISO 20387:2018 biobanking requirements.
- Factory-calibrated pressure-relief valve and rupture disk assembly compliant with PED 2014/68/EU and EN 13445-3 safety standards for cryogenic pressure equipment.
Sample Compatibility & Compliance
The GT Series accommodates diverse biological specimens—including human oocytes and embryos (IVF applications), bovine/ovine semen straws, equine frozen semen doses, microbial cultures, stem cell lines, and primary tissue explants. All internal components are certified non-cytotoxic (ISO 10993-5) and free of leachable heavy metals. The tanks meet ISO 13485:2016 requirements for medical device manufacturing quality systems and support GLP-compliant recordkeeping when paired with validated LN₂ level monitoring accessories. For veterinary and dairy applications, models conform to EU Regulation (EC) No 853/2004 hygiene standards for animal by-products handling.
Software & Data Management
While the GT Series is a passive storage platform, it integrates seamlessly with optional digital monitoring solutions—including wireless LN₂ level sensors (e.g., Froilabo CryoView™), cloud-connected loggers (supporting MQTT/HTTPS protocols), and audit-trail-capable data management platforms compliant with FDA 21 CFR Part 11. Temperature and fill-level data can be exported in CSV or XML format for inclusion in institutional biobank LIMS or electronic lab notebooks (ELN). Firmware updates and calibration certificates are traceable via unique serial-number-based digital product passports.
Applications
- In vitro fertilization (IVF) clinics requiring reliable, low-contamination storage for gametes and blastocysts over multi-week treatment cycles.
- Large-scale animal breeding operations maintaining genetic repositories of bovine, ovine, caprine, and porcine germplasm.
- Dairy research laboratories preserving starter cultures, probiotic strains, and fermented product isolates under GMP-aligned conditions.
- Veterinary diagnostic centers archiving pathological specimens, vaccine seed stocks, and zoonotic pathogen isolates.
- Academic core facilities supporting cryopreservation workflows for induced pluripotent stem cells (iPSCs), organoids, and CRISPR-edited cell lines.
FAQ
What is the difference between vapor-phase and liquid-phase storage in the GT Series?
Vapor-phase storage maintains samples above the LN₂ surface (typically –150 °C to –190 °C), reducing cross-contamination risk during retrieval; liquid-phase immersion achieves –196 °C but requires strict quarantine protocols for infectious samples.
Can the GT tanks be used in cleanroom environments?
Yes—aluminum surfaces are compatible with ISO Class 5–8 cleanroom disinfection protocols (e.g., 70% isopropanol, hydrogen peroxide vapor), and particulate generation is negligible due to anodized finish and absence of gaskets or polymer seals.
Is validation documentation available for IQ/OQ/PQ protocols?
Froilabo provides factory-issued test reports (thermal mapping, vacuum decay, pressure testing) and supports user-defined qualification protocols with template SOPs and traceable calibration records.
How does ambient temperature affect static hold time?
Hold time is rated at 20 °C ambient; every +5 °C increase reduces duration by ~8–12% depending on model size and fill level—detailed derating curves are provided in the technical manual.
Are replacement parts and service support available globally?
Yes—authorized service centers in North America, EMEA, and APAC provide certified repair, vacuum reconditioning, and annual performance verification per ISO/IEC 17025 guidelines.
