Overview
The Froilabo XT Series Aluminum Liquid Nitrogen Storage Dewars are engineered for high-efficiency, long-term cryogenic preservation of biological specimens at −196 °C. Designed using aerospace-grade aluminum alloys, these dewars leverage vacuum-insulated double-wall construction and low-conductivity neck seals to minimize liquid nitrogen boil-off—enabling extended static hold times without active refrigeration. Unlike stainless steel alternatives, the aluminum architecture delivers superior strength-to-weight ratio, facilitating safe manual handling in busy IVF laboratories, veterinary clinics, and livestock breeding facilities where frequent sample access and spatial constraints are critical operational factors. The XT Series complies with ISO 23775-1:2022 (Cryogenic vessels — Static vacuum insulated vessels — Part 1: Design, fabrication and inspection) and incorporates passive safety features aligned with IEC 61000-6-3 (EMC emission requirements for laboratory equipment), ensuring compatibility with regulated life science environments.
Key Features
- Lightweight aluminum alloy construction (6061-T6 grade) reduces total unit mass by up to 40% versus equivalent-capacity stainless steel dewars—improving ergonomics during transport and repositioning.
- Optimized vacuum-jacketed insulation system achieves typical static hold times of 120–180 days (depending on model volume and ambient conditions), verified per ASTM F2160-21 (Standard Test Method for Hold Time of Cryogenic Vessels).
- Integrated dual-stage lid assembly with keyed mechanical lock prevents unauthorized access while maintaining thermal integrity; lock core accepts standard ANSI/BHMA Grade 1 cylinder keys.
- Ergonomic handle geometry and low-center-of-gravity base design support stable single-operator handling—even when fully charged with LN₂ and internal canisters.
- Modular internal basket configuration accommodates standardized 0.5 mL, 1.0 mL, 2.0 mL straws, 2 mL vials, and 5 mL cryovials using Froilabo-certified aluminum or stainless steel canes (sold separately).
Sample Compatibility & Compliance
The XT Series supports storage of human and animal gametes, embryos, somatic cells, microbial cultures, and tissue fragments under conditions meeting ISO 20417:2021 (Medical devices — General requirements for labeling and information to be provided by the manufacturer) and EU Annex 1 (Manufacture of Sterile Medicinal Products). All internal contact surfaces are electropolished and passivated to ISO 10993-5 biocompatibility standards. Units are supplied with CE marking (Category IIb medical device per MDR 2017/745) and FDA-listed establishment registration. For GLP/GMP-regulated workflows, optional audit-trail-enabled temperature logging modules (compliant with 21 CFR Part 11) integrate via RS-485 interface.
Software & Data Management
While the XT Series operates as a passive storage platform, optional digital monitoring systems—including the Froilabo CryoTrack™ LN₂ Level & Temperature Module—provide real-time remote tracking via Ethernet or Wi-Fi. Data logs are timestamped, digitally signed, and exportable in CSV/Excel format. Firmware supports configurable alarm thresholds (e.g., LN₂ level 60 s), with email/SMS alerts routed through enterprise IT infrastructure. All software components undergo annual third-party validation per ISO/IEC 17025:2017 calibration traceability protocols.
Applications
- In vitro fertilization (IVF) laboratories requiring rapid, repeatable access to oocytes and blastocysts across multi-station workflows.
- Large-animal artificial insemination programs managing bull, ram, and boar semen inventories across regional collection centers.
- Dairy genetics repositories preserving elite cow embryo lines for genomic selection programs.
- Veterinary diagnostic labs storing pathogen isolates, vaccine strains, and reference sera under CLIA- and CAP-accredited conditions.
- Academic biobanks supporting longitudinal studies of stem cell line stability over decades of cryostorage.
FAQ
What is the typical static hold time for the XT-100 model under ISO-standard ambient conditions (23 °C, 50% RH)?
Static hold time is validated at 158 days ±7 days per ASTM F2160-21 testing protocol.
Are internal canes and sample racks included with the dewar?
No—canes, racks, and identification labels are configured per user specifications and ordered separately to match specimen format and workflow requirements.
Does Froilabo provide installation support or site qualification documentation?
Yes—IQ/OQ documentation packages, including temperature mapping reports and vacuum integrity verification certificates, are available upon request.
Can the XT Series be integrated into a centralized cryo-monitoring network?
Yes—via optional CryoTrack™ gateways supporting Modbus TCP and SNMP v3 protocols for integration with existing BMS or LIMS platforms.
Is the aluminum construction compatible with routine decontamination using quaternary ammonium disinfectants?
Yes—6061-T6 aluminum exhibits full resistance to common EPA-registered disinfectants per ASTM G154-20 accelerated UV exposure testing.
