Overview
The Zhongke Duling YDS-2-30 is a portable, vacuum-insulated liquid nitrogen (LN₂) storage container engineered for reliable short- to medium-term cryopreservation of biological specimens in field, clinical, and laboratory environments. Utilizing double-walled stainless steel construction with high-efficiency multilayer superinsulation (MLI) and low-conductivity fiberglass-reinforced support rods, the unit minimizes heat influx and extends hold time without active cooling. Its compact footprint (Ø224 mm × 420 mm H), lightweight design (2.3 kg empty), and ergonomic handle enable safe manual transport between labs, operating rooms, or mobile collection sites—making it suitable for biobanking workflows requiring intermittent LN₂ replenishment rather than continuous ultra-low-temperature operation.
Key Features
- Vacuum-jacketed stainless steel inner and outer vessels with helium-leak-tested integrity for long-term thermal stability
- Fiberglass-reinforced support structure replacing traditional metal neck tubes to reduce solid conduction losses by >40% versus conventional designs
- Multi-tier square canister rack system (standard configuration) accommodating up to 1,200 standard 2 mL cryovials per full load
- High-strength, non-toxic EPDM rubber gasket seal on the lid ensuring consistent vapor-phase or liquid-phase storage conditions
- Corrosion-resistant anodized aluminum neck tube and lid assembly rated for sustained exposure to −196°C
- Lockable lid mechanism (optional accessory lock available; 30 mm neck aperture supports standard locking hardware)
- Integrated adsorbent material (activated charcoal + molecular sieve) within the vacuum space to maintain low-pressure integrity over extended service intervals
Sample Compatibility & Compliance
The YDS-2-30 is validated for storage of human and animal-derived biospecimens including sperm, oocytes, embryos, stem cells, tissue sections, and primary cell cultures. It complies with ISO 13485:2016 requirements for medical device storage systems when deployed in clinical laboratories under documented SOPs. While not certified as a Class II medical device itself, its design aligns with key elements of ISO 20387:2018 (Biobanking — General requirements for biobank operations) regarding temperature uniformity, monitoring capability, and sample traceability support. Units are supplied with CE-marked electrical safety documentation for ancillary accessories (e.g., optional electronic level sensors) and meet RoHS 3 Directive restrictions on hazardous substances.
Software & Data Management
As a passive cryogenic storage system, the YDS-2-30 does not incorporate embedded electronics or firmware. However, it is fully compatible with third-party LN₂ level monitoring solutions—including ultrasonic fill-level transducers and wireless temperature loggers—that interface via standard 4–20 mA or Bluetooth Low Energy (BLE) protocols. When integrated into GLP/GMP-compliant environments, users may deploy validated external data loggers meeting FDA 21 CFR Part 11 requirements for audit trail generation, electronic signatures, and secure data export (CSV/PDF). Documentation packages include calibration certificates for optional sensor add-ons and IQ/OQ templates aligned with ISO/IEC 17025 accreditation criteria.
Applications
- Transport and temporary holding of cryopreserved samples between IVF clinics and central biorepositories
- Field-based collection of genomic samples during epidemiological studies or veterinary outreach programs
- Backup storage during scheduled maintenance of large-scale mechanical ultra-low freezers (−80°C)
- On-site embryo transfer procedures requiring immediate access to vitrified oocytes or blastocysts
- Quality control sampling in pharmaceutical manufacturing where intermediate stability testing requires cryo-archiving
- Academic research labs conducting longitudinal studies with limited infrastructure for permanent LN₂ infrastructure
FAQ
What is the typical hold time for the YDS-2-30 at ambient temperature?
Under ISO 23747-defined test conditions (25°C ambient, 50% RH, no solar loading), the YDS-2-30 achieves ≥25 days of static hold time from full fill (2.8 L LN₂) to complete evaporation.
Can this container be used for vapor-phase storage?
Yes—the internal geometry and thermal gradient profile support stable vapor-phase operation at −150°C to −190°C depending on fill level and ambient conditions; recommended for sensitive cell types requiring reduced thermal shock.
Is the unit compliant with IATA Dangerous Goods Regulations for air transport?
No—this model is not UN-certified for air shipment of liquid nitrogen. For regulated transport, users must select IATA-compliant variants (e.g., YDS-10-210 with pressure-relief venting and UN 2037 marking) or utilize dry shipper configurations.
What maintenance is required to sustain vacuum integrity?
Annual visual inspection of outer shell integrity and periodic verification of vacuum level using a calibrated Pirani gauge are recommended; full re-evacuation is typically required every 5–7 years under normal usage.
Are custom rack configurations available for specialized vial formats?
Yes—Zhongke Duling offers OEM-compatible rack inserts for 0.5 mL, 1.8 mL, and 5.0 mL straws, as well as grid-based racks for microtiter plates (96-well format) upon request with minimum order quantities.
