Banagee YDS-3 3-Liter Static Liquid Nitrogen Storage Dewar

Overview

The Banagee YDS-3 is a compact, static liquid nitrogen storage dewar engineered for reliable, low-maintenance cryopreservation of biological specimens in academic, clinical, and industrial laboratories. Designed exclusively for static (non-transfer, non-transport) operation, it utilizes vacuum-insulated double-walled aluminum construction to minimize boil-off while maximizing thermal stability. Unlike active cryogenic systems requiring continuous monitoring or automated refilling, the YDS-3 operates passively—relying on high-efficiency multilayer reflective insulation and optimized neck geometry to achieve a static evaporation rate of just 0.12 L/day. This enables uninterrupted storage for up to 26 days between refills under ambient laboratory conditions (20–25 °C), making it ideal for short-to-medium-term archival of cell lines, primary tissues, sperm, oocytes, and microbial strains where frequent access and long-term unattended holding are required.

Key Features

• Vacuum-insulated dual-aluminum wall architecture with multi-layer reflective shielding for consistent thermal performance and structural integrity
• Lightweight yet robust anodized aluminum body with electrostatically applied powder coating—resistant to chipping, corrosion, and routine decontamination protocols
• Secure locking lid assembly with integrated gasket seal to prevent unauthorized access and reduce vapor loss during intermittent use
• Six standardized 38 mm-diameter × 120 mm-height canisters, each accommodating three cryovial storage strips (6 vials/strip = 54 vials per canister)
• Optimized neck geometry (50 mm opening) balancing sample accessibility with minimized heat ingress and nitrogen loss
• Compliance with GB/T 5458–2012, the People’s Republic of China national standard for liquid nitrogen biological storage containers, covering design, safety, performance testing, and labeling requirements

Sample Compatibility & Compliance

The YDS-3 supports common cryogenic sample formats including externally threaded 0.5–2.0 mL cryovials (Nunc, Corning, Thermo Fisher), standardized cryovial strips, and labeled cryoboxes compatible with 38 mm canister dimensions. Its static configuration ensures minimal thermal cycling and mechanical disturbance—critical for preserving viability in sensitive primary cells and gametes. While not certified to ISO 13485 or FDA 21 CFR Part 11 (as it lacks electronic logging or user authentication), its physical design and material traceability align with GLP-aligned laboratory practices for non-GMP biobanking workflows. Vacuum integrity is validated per GB/T 5458–2012 Annex B, with five-year vacuum warranty supporting long-term operational confidence.

Software & Data Management

The YDS-3 is a fully manual, analog storage system with no embedded electronics, firmware, or connectivity interfaces. It does not include software, data logging, remote monitoring, or audit trail capabilities. Users are expected to maintain independent records—including LN₂ refill dates, inventory logs, and temperature verification (via external calibrated thermocouple probes inserted through the neck)—in accordance with institutional SOPs. For laboratories requiring digital traceability, integration with third-party environmental monitoring platforms (e.g., Sensaphone, DicksonOne) is possible using external PT100 or thermistor sensors placed within the vapor phase above the liquid level.

Applications

• Short-to-intermediate term storage (≤26 days) of mammalian cell lines, hybridomas, and stem cell derivatives in research labs
• Backup storage for critical clinical specimens prior to transfer to ultra-low temperature freezers or long-term vapor-phase tanks
• Cryopreservation of plant meristems, fungal spores, and bacterial glycerol stocks in agricultural and microbiological facilities
• On-site holding of frozen reagents, antibodies, and enzyme preparations requiring stable sub-150 °C conditions
• Educational use in undergraduate and graduate teaching labs demonstrating cryogenic principles and sample handling best practices

FAQ

Is the YDS-3 suitable for long-term storage beyond 26 days?
No—the 26-day hold time is calculated at 20–25 °C ambient and assumes consistent fill level and lid closure. For archival storage exceeding one month, vapor-phase liquid nitrogen tanks with active monitoring or mechanical refrigeration systems are recommended.
Can this dewar be used for transporting samples?
No—it is explicitly designed for static, stationary use only. Transport applications require UN-certified, shock-tested, and pressure-relief-equipped portable dewars compliant with IATA/ADR regulations.
Does the YDS-3 meet international standards such as ISO or ASTM?
It conforms to GB/T 5458–2012, the Chinese national standard for biological liquid nitrogen containers. It is not certified to ISO 20739, ASTM F2168, or other international cryostorage standards, as those apply primarily to larger, actively monitored systems.
What maintenance is required during the 5-year vacuum warranty period?
No scheduled maintenance is required. Users should visually inspect the outer shell for dents or coating damage, verify lid seal integrity before each use, and avoid exposing the unit to moisture or corrosive vapors that could compromise vacuum jacket integrity.
Are replacement canisters or custom accessories available?
Standard 38 mm × 120 mm aluminum canisters are available directly from Banagee distributors. Custom-fit foam inserts, barcode-labeled canister caps, and vapor-phase temperature monitoring kits may be sourced through authorized lab supply partners.
