Banagee YDS-6-80 6-Liter Static Liquid Nitrogen Storage Dewar with 80 mm Wide Mouth

Overview

The Banagee YDS-6-80 is a static, non-pressurized liquid nitrogen (LN₂) storage dewar engineered for reliable, long-term cryopreservation of biological specimens in academic, clinical, and industrial laboratory environments. Designed according to the principles of passive vacuum insulation, it utilizes a double-walled aluminum construction with multi-layer reflective superinsulation (MLI) to minimize heat influx and suppress boil-off. Unlike active or transport-oriented dewars, the YDS-6-80 operates exclusively in static storage mode—meaning it is intended for stationary use where frequent access is not required, and where maximum hold time and thermal stability are prioritized over mobility or rapid sample retrieval. Its 80 mm wide mouth enables unobstructed insertion and extraction of standard cryogenic accessories—including 63 mm-diameter storage buckets—and supports compatibility with automated rack handlers used in medium-throughput biorepositories.

Key Features

• High-efficiency vacuum insulation system delivering a static evaporation rate of just 0.18 L/day, enabling up to 33 days of continuous LN₂ retention at ambient temperatures (20 °C, still air)
• Lightweight yet robust aerospace-grade aluminum alloy outer and inner vessels—optimized for mechanical durability and thermal inertia without compromising portability
• Electrostatic powder-coated exterior finish, eliminating flaking, chipping, and VOC emissions associated with conventional solvent-based paints
• Integrated locking lid mechanism with dual-point engagement to prevent accidental opening and ensure biosample integrity during unattended operation
• Six standardized 63 mm × 120 mm aluminum storage buckets, each accommodating 11 cryo-racks (6 vials per rack), for a total capacity of 198 individually barcoded 1.2–2.0 mL cryovials
• Five-year vacuum integrity warranty—validated through accelerated aging tests per GB/T 5458–2012—and one year of comprehensive functional coverage

Sample Compatibility & Compliance

The YDS-6-80 supports long-term storage of primary human tissues, peripheral blood mononuclear cells (PBMCs), stem cell suspensions, oocytes, embryos, microbial cultures, and purified nucleic acid libraries—all within the stable –196 °C cryogenic environment maintained by liquid nitrogen. Its geometry and bucket configuration conform to ISO/TC 276 standards for biobanking infrastructure interoperability. The dewar meets the dimensional, performance, and safety requirements outlined in GB/T 5458–2012 (“Liquid Nitrogen Containers for Biological Use”), including thermal loss verification, pressure relief functionality (via integrated venting path), and structural load testing under filled conditions. While not certified to FDA 21 CFR Part 11 or EU Annex 11 out-of-the-box, its design permits integration into GLP- and GMP-aligned workflows when paired with validated temperature monitoring systems and electronic logbook protocols.

Software & Data Management

As a passive storage device, the YDS-6-80 does not incorporate onboard electronics or embedded firmware. However, it is fully compatible with third-party LN₂ level monitoring systems—including ultrasonic fill-level sensors, wireless temperature probes (e.g., −200 °C thermocouples), and cloud-connected IoT gateways—that interface via analog 4–20 mA or digital RS-485 outputs. When deployed in networked biorepository settings, the dewar can be assigned a unique asset ID and tracked within LIMS platforms (e.g., LabVantage, STARLIMS) using barcode-labeled buckets and racks. Audit trails for LN₂ refills, maintenance events, and access logs may be maintained manually or synchronized via CSV/API ingestion—supporting traceability requirements under ISO 20387 and CAP accreditation frameworks.

Applications

• Long-term archival storage of clinical-grade cell therapies in university core facilities
• Backup cryostorage for genomic DNA/RNA libraries in NGS service laboratories
• Secondary containment for high-value hybridoma clones and monoclonal antibody-producing cell lines
• Field-deployable backup dewar for mobile biobanking units operating in resource-constrained regions
• Educational use in undergraduate molecular biology labs for cryopreservation technique training
• Compliance-driven cold chain redundancy in pharmaceutical QC labs conducting stability studies per ICH Q5C

FAQ

Is the YDS-6-80 suitable for liquid nitrogen transportation?
No. It is strictly a static storage dewar and lacks pressure-relief valves, impact-resistant casing, or UN/DOT certification required for transport.
Can I retrofit this dewar with an electronic level monitor?
Yes—its cylindrical neck geometry and standardized 80 mm aperture accept commercially available ultrasonic or capacitance-based LN₂ sensors with mounting flanges.
What is the recommended refill frequency under typical lab conditions?
With ambient temperature at 22 °C and relative humidity ≤60%, refilling every 28–33 days maintains optimal LN₂ volume above the critical 20% threshold for sample immersion.
Does the five-year vacuum warranty cover accidental physical damage?
No—the warranty applies solely to vacuum degradation due to material fatigue or seal failure under normal use; dents, drops, or improper handling void coverage.
Are replacement buckets and gaskets available as spare parts?
Yes. Banagee supplies OEM-compatible aluminum buckets (part #YDS-BKT-63×120), silicone O-rings (part #YDS-SEAL-80), and locking lid assemblies (part #YDS-LID-LOCK) through authorized distributors.
