Manufacturer Description
The Thermo Scientific Locator 8 Plus is a premium, maximum-density cryogenic storage dewar engineered for highly organized ultra-low temperature preservation of biological specimens. As part of the advanced "Plus" series, this vessel incorporates optimized vacuum insulation and a refined narrow-mouth design to achieve industry-leading liquid nitrogen economy. The Locator 8 Plus features an 8-rack hanging grid assembly, allowing laboratories to segregate and catalog large sample lots into discrete, independent zones. By providing uniform thermal profiles below -180°C throughout the entire chamber—even during minimal liquid levels—this passive system ensures absolute specimen viability and security without relying on electrical grid power or mechanical compressors.
Technical Specifications
- Total Internal Volume: 111 Liters
- Liquid Nitrogen Capacity: 61 Liters (Optimized lower-fill volume to maximize vapor phase security)
- Static Evaporation Rate: ~0.60 Liters per day (High-efficiency thermal boundary insulation)
- Static Holding Time: Up to 101 Days under static conditions
- Storage Configuration: Accommodates 8 independent vertical hanging racks (accommodating standard 2-inch / 5cm cryoboxes)
- Maximum Vial Capacity: Up to 1,600 standard 2.0 mL cryogenic vials (using 2" 100-vial boxes)
- Neck Opening Diameter: 8.5 inches (215 mm) for precision extraction
- Dimensions: 22" Diameter x 37.5" Height (55.9 cm x 95.3 cm)
- Weight (Empty): Approx. 90 lbs (41 kg)
- Value-Add: Equipped with a high-visibility orange insulation lid and a precision-molded, numbered index ring to facilitate rapid rack location identification, preventing prolonged ambient air infiltration.
System Compatibility
The Locator 8 Plus is compatible with standard, universally sized cryogenic workflow hardware:
- Hanging Racks: Designed specifically for Thermo Scientific 8-position vertical box canisters (standard 2-inch box footprint).
- Cryobox Systems: Accepts 2-inch plastic, polycarbonate, or specialized water-repellent cardboard cryoboxes (typically 5" x 5" grids).
- Level Monitoring: While this unit operates as a highly secure passive vessel without a monitor, the lid structure features a standard integrated pass-through port to accept an optional Thermo Scientific ultrasonic liquid level monitor if needed in the future.
- Mobility: Fully compatible with standard Thermo Scientific heavy-duty castered dewar dollies for secure mobility.
Applications
The professional standard for high-density, categorized biological archiving:
- Clinical Research Trials: Segregating diverse patient sample sets into separate, dedicated index racks to prevent cross-contamination.
- Stem Cell & Cord Blood Banking: Ensuring secure, long-term vapor or liquid immersion preservation for high-value therapeutic cell lots.
- Biotechnology Master Lots: Archiving pristine, unmutated bacterial master seed stocks and monoclonal antibodies.
- Academic Sample Archiving: Providing secure backup storage for multiple laboratory groups within a single centralized department dewar.
