The Thermo Scientific Locator Rack and Box Systems simplify sample storage and retrieval with unique hanging rack and gridded box design, advanced vacuum insulation, and unmatched temperature uniformity.

• Also holds 648 5mL Vials
• Includes (4) indexed stainless-steel vial racks designed for use with 2" Nalgene Cryogenic Boxes (boxes sold separately below)
• Outstanding temperature uniformity: samples are stored below -180°C even when less than 2" (5 cm) of liquid nitrogen remains in the vessel
• Advanced vacuum insulation minimizes liquid nitrogen evaporation and reduces operating costs
• Secure locking clasp prevents unauthorized entry
• Ultrasonic Level Monitor safeguards irreplaceable samples with minimal liquid nitrogen evaporation and conduction
• Monitor provides continuous LED readout of liquid nitrogen level and activates visual and audible alarms when level falls below safe range of approximately 1"
• Alarm also alerts operator in the event of excessive liquid nitrogen loss
• Total 1.2/2.0 mL Vial Capacity: 1600
• 4 Boxes fit in each rack, and 100 vials fits in each box for a total of 1600 total vial capacity
