Manufacturer Description
The Barnstead Thermolyne Locator 4 is a high-density, ultra-insulated cryobiological storage dewar engineered for the long-term preservation of biological samples at liquid nitrogen temperatures. Designed specifically to maximize storage capacity while maintaining a compact laboratory footprint, the Locator 4 features an advanced double-wall vacuum insulation matrix that dramatically reduces static evaporation rates. Its narrow-mouth neck design ensures outstanding internal temperature uniformity, keeping samples safely below -180°C even when as little as 2 inches (5 cm) of liquid nitrogen remains in the vessel. With its completely passive, compressor-free operation, this vessel provides foolproof thermal security for high-value research specimens, cell lines, and clinical samples.
Technical Specifications
- Total Internal Volume: 111 Liters
- Liquid Nitrogen Capacity: 90 Liters
- Static Evaporation Rate: ~0.65 to 0.99 Liters per day (dependent on ambient environment and lid cycles)
- Static Holding Time: Up to 112 Days
- Sample Capacity: Holds up to 4 inventory racks (accommodating 9x9 or 10x10 cryoboxes)
- Maximum Vial Capacity: Up to 3,600 standard 2.0 mL cryogenic vials (using 100-vial boxes)
- Neck Opening Diameter: 8.5 inches (215 mm) for easy rack insertion and extraction
- Dimensions: 22" Diameter x 37.5" Height (55.9 cm x 95.3 cm)
- Weight (Empty): Approx. 90 lbs (41 kg)
- Value-Add: Features an integrated, numbered index ring around the neck opening to ensure exact, fast placement and tracking of individual inventory racks, minimizing open-lid thermal exposure.
System Compatibility
The Locator 4 vessel accepts standard laboratory inventory management hardware and accessories:
- Inventory Racks: Compatible with classic Thermolyne 4-pot vertical hanging racks (typically holding 9 or 10 boxes per rack).
- Cryobox Systems: Accommodates standard 2-inch plastic or water-repellent cardboard cryoboxes (3.25" x 3.25" or standard grids).
- Mobility: Universally compatible with the Thermolyne / Thermo Scientific heavy-duty castered dewar dolly for safe laboratory transport.
Applications
The definitive choice for secure, ultra-low-temperature archiving:
- Biorepository Storage: Long-term archiving of genomic samples, tissue cultures, and pristine clinical specimen lots.
- Cell Culture Preservation: Maintaining hybridomas, stem cells, and primary cell lines in stable vapor-phase or liquid-immersion environments.
- IVF Clinics: Secure cryopreservation of oocytes, embryos, and sperm samples.
- Academic Research: Fail-safe master strain banking for microbiology and molecular biology labs without the risk of power-outage losses.
