Banagee YDS-15 15-Liter Embryo Storage Liquid Nitrogen Cryogenic Container

Overview

The Banagee YDS-15 is a static-phase, upright liquid nitrogen (LN₂) cryogenic storage container engineered specifically for long-term, ultra-low-temperature preservation of sensitive biological specimens—including human and animal embryos, oocytes, spermatozoa, stem cells, and primary cell lines. Operating at approximately –196 °C, the YDS-15 leverages high-vacuum multilayer insulation (MLI) technology within a seamless, double-walled aluminum vessel to minimize heat ingress and sustain cryogenic stability without active refrigeration or mechanical cooling. Its design adheres to the thermal performance and structural safety requirements defined in GB/T 5458–2012, the Chinese national standard for liquid nitrogen biological containers, ensuring consistent thermal efficiency, mechanical integrity, and operator safety under routine laboratory conditions.

Key Features

• High-strength, lightweight aerospace-grade aluminum alloy construction—optimized for durability, corrosion resistance, and thermal stability across repeated fill cycles.
• Multi-layer vacuum insulation system with reflective MLI wraps—reducing static evaporation rate to just 0.11 L/day and enabling uninterrupted LN₂ retention for up to 134 days at ambient temperature (25 °C).
• Integrated locking lid assembly—prevents unauthorized access and accidental opening during transport or unattended operation, critical for chain-of-custody integrity in ART (Assisted Reproductive Technology) and biobanking workflows.
• Ergonomic, powder-coated exterior finish—resists chipping, scratching, and chemical exposure while facilitating easy decontamination between uses.
• Modular internal configuration: six standardized 38-mm-diameter × 120-mm-height canisters, each accommodating three 0.5-mL or 1.0-mL cryogenic straws; total capacity supports 54 cryovials (assuming six vials per straw), scalable via optional accessory racks.
• Engineered neck geometry (50-mm diameter opening) balances sample accessibility with minimized vapor loss—compatible with standard cryo-handling tools, automated retrieval systems, and barcode-scanning probes.

Sample Compatibility & Compliance

The YDS-15 is validated for storage of cryopreserved reproductive tissues compliant with international clinical standards including ISO 20416:2020 (Biobanking — General requirements for biobank operations) and ICMR/ASRM guidelines for embryo cryostorage. Its stable thermal gradient—from vapor phase (–150 °C to –190 °C) to liquid phase (–196 °C)—supports both vapor-phase and submerged storage protocols. All materials in direct contact with samples meet USP Class VI biocompatibility criteria. The unit is not intended for transport under regulatory shipping classifications (e.g., UN 1977); it is strictly for stationary, in-laboratory use. Documentation includes full traceability of vacuum integrity testing and batch-specific thermal performance certification per GB/T 5458–2012 Annex B.

Software & Data Management

As a passive static storage system, the YDS-15 does not incorporate onboard electronics, sensors, or connectivity. However, it is fully compatible with third-party LN₂ level monitoring platforms (e.g., CryoView™, MVE SmartSensor™) via optional ultrasonic or capacitive probe integration kits. When deployed in GLP- or GMP-aligned environments, users may log fill dates, inventory movements, and vacuum integrity checks using electronic lab notebooks (ELNs) that support 21 CFR Part 11-compliant audit trails. Banagee provides editable Excel-based inventory templates and QR-coded canister labels to support sample tracking interoperability with LIMS systems such as LabVantage or STARLIMS.

Applications

• Long-term static cryopreservation of human embryos and gametes in IVF clinics and reproductive medicine centers.
• Secure backup storage for induced pluripotent stem cell (iPSC) lines and primary tissue isolates in academic and contract research organizations.
• Secondary cold chain redundancy for biobanks participating in national or international specimen-sharing consortia (e.g., BBMRI-ERIC).
• Low-cost, low-maintenance archival storage for veterinary biorepositories and agricultural germplasm banks.
• Teaching laboratories requiring reliable, entry-level LN₂ infrastructure for undergraduate and graduate cryobiology instruction.

FAQ

Is the YDS-15 suitable for vapor-phase storage of sensitive stem cell lines?

Yes—the optimized neck geometry and thermal profile maintain stable vapor-phase temperatures between –150 °C and –190 °C, minimizing thermal shock and ice crystal propagation during routine access.
What maintenance is required to uphold the 5-year vacuum warranty?

No scheduled maintenance is required; however, users must avoid mechanical impact to the outer shell, refrain from using abrasive cleaners on the neck tube, and ensure the lid gasket remains free of frost accumulation and physical deformation.
Can the YDS-15 be integrated into an existing LIMS or biobank management system?

While the unit itself lacks native connectivity, its standardized dimensions, canister layout, and labeling compatibility enable seamless integration with barcode-driven inventory systems and external LN₂ monitoring hardware.
Does Banagee provide calibration certificates or performance validation reports?

Upon request, Banagee issues a factory-verified thermal performance report—including measured static evaporation rate, hold time verification, and vacuum decay test results—traceable to CNAS-accredited metrology labs.
Is the YDS-15 certified for use in ISO 13485–registered medical device manufacturing facilities?

The YDS-15 is not a medical device but a Class I laboratory consumable; it complies with GB/T 5458–2012 and may be included in facility QMS documentation as a qualified ancillary storage asset under ISO 13485 clause 7.5.10 (Control of monitoring and measuring equipment).
