Overview
The WIGGENS Universal Cylindrical Dewar Flask 00C is a high-performance, laboratory-grade cryogenic storage vessel engineered for stable, low-evaporation containment of liquid nitrogen (LN₂), dry ice slurries, and other sub-ambient substances. Based on the classical double-walled vacuum insulation principle—where an evacuated annular space between outer metal shell and inner borosilicate glass liner minimizes conductive and convective heat transfer—the 00C series delivers reproducible thermal performance across standardized operating conditions (–196 °C for LN₂). Designed for routine use in analytical labs, biobanks, and materials testing facilities, this dewar prioritizes mechanical robustness, operator safety, and long-term dimensional stability under repeated thermal cycling.
Key Features
- Double-walled construction with high-vacuum interstitial space (≤10⁻³ mbar residual pressure) ensuring low heat influx and extended hold times
- Inner liner fabricated from DIN 8554-compliant 3.3 borosilicate glass (e.g., Schott Duran®), offering exceptional thermal shock resistance (ΔT ≥ 120 °C) and chemical inertness toward cryogens
- Full-silvered inner surface (reflectivity >95% at 10 µm wavelength) to suppress radiative heat transfer—standard on all models; optional observation-window variants available with aligned apertures in both shell and liner
- Exterior housing in powder-coated blue steel (C-series) or ergonomically enhanced G-C-series with integrated stainless-steel carrying handles for safe handling during fill/transfer operations
- Modular lid system compatible with standard stoppers, foam plugs, or optional anti-evaporation insulated covers (sold separately) to further reduce boil-off rates during static storage
- Dimensionally referenced to ISO 8573-1:2010 mounting interfaces and ASTM F2624-18 labeling conventions for traceable inventory management
Sample Compatibility & Compliance
The 00C dewar supports passive cryopreservation of biological samples (e.g., cell suspensions, tissue fragments), calibration standards (e.g., ITS-90 fixed-point materials), and thermally sensitive reagents. Its non-magnetic stainless-steel exterior and glass interior eliminate contamination risks associated with metallic leaching. All units comply with EU Directive 2014/68/EU (PED) for pressure equipment classification (Category I, non-pressurized), EN 61000-6-3:2019 (EMC immunity), and are CE-marked per Machinery Directive 2006/42/EC. Documentation includes full material declarations (RoHS 2011/65/EU, REACH SVHC), batch-specific vacuum integrity test reports, and conformity statements supporting GLP and ISO/IEC 17025 audit readiness.
Software & Data Management
While the 00C is a passive storage device without embedded electronics, its standardized geometry and part-numbering scheme (e.g., 102100C, 102200C) integrate seamlessly into LIMS and electronic lab notebook (ELN) platforms via barcode-scannable labels. Each unit carries a permanent laser-engraved serial number and model identifier compliant with GS1 DataMatrix standards. Optional temperature-monitoring accessories—including calibrated Pt100 probe sleeves and wireless LN₂ level transducers—interface with third-party data loggers meeting FDA 21 CFR Part 11 requirements for audit-trail generation and electronic signature validation.
Applications
- Long-term storage of cryopreserved primary cells, stem cell lines, and microbial cultures at –196 °C
- Transport and temporary holding of LN₂-cooled NMR sample probes and superconducting magnet shims
- Calibration of low-temperature sensors (thermocouples, RTDs) against ITS-90 reference points
- Controlled-rate freezing support in conjunction with programmable freezers (e.g., N70 series)
- Sub-ambient reaction quenching and solvent trapping in synthetic chemistry workflows
- Reference standard storage for metrology labs accredited to ISO/IEC 17025:2017
FAQ
What is the typical liquid nitrogen hold time for the 00C series?
Hold time varies by model volume and ambient conditions. For example, the 100 mL 00C (Art. No. 102100C) maintains ~70 hours at 23 °C ambient; the 1250 mL variant (1027) achieves ~118 hours. Evaporation rates are measured per ASTM F1505-20 Annex A1 under controlled humidity (50% RH) and still-air conditions.
Can the dewar be used with liquid argon or oxygen?
Yes—provided compatibility with the 3.3 borosilicate glass liner and absence of organic contaminants. However, due to differing saturation pressures and thermal expansion coefficients, users must verify mechanical integrity and venting protocols per CGA P-1 and ISO 8573-9:2018 guidelines.
Is the silvered inner surface removable or serviceable?
No—the silvering is a permanent, vacuum-deposited coating applied during liner manufacturing. It is not user-serviceable and must be preserved during cleaning (use only lint-free cloths and ethanol; avoid abrasives or ultrasonics).
Are custom aperture configurations available for imaging applications?
Yes. WIGGENS offers OEM-configured observation-window variants (designated “-OV”) with optically aligned 25 mm or 50 mm diameter apertures in both shell and liner, suitable for in situ optical monitoring or fiber-optic sensor integration.
Does the dewar require periodic vacuum reconditioning?
Vacuum integrity is guaranteed for 5 years from date of manufacture. Annual verification using a calibrated Pirani gauge is recommended per ISO 21649:2021. Re-evacuation services are available through authorized WIGGENS service centers upon request.
