Retrieve cell samples quickly and easily using Thermo Scientific™ Locator™ cryogenic rack and box systems, which feature a unique hanging rack and gridded box design, advanced vacuum insulation, unmatched temperature uniformity and an innovative liquid nitrogen monitor.

• Compact design minimises space requirements while maximising storage capacity

• System is suitable for both manual and computerised inventory record-keeping methods
• Super-insulated vessels have special, narrow-mouth design that conserves liquid nitrogen by minimising evaporation
• Samples are stored below –180 °C, even when less than 5 cm of liquid nitrogen remains in the vessel
• Ultrasonic Level Monitor safeguards irreplaceable samples with minimal liquid nitrogen evaporation and conduction
• Advanced vacuum insulation minimises liquid nitrogen evaporation and reduces operating costs
• Secure locking hasp prevents unauthorised entry
• Locator 8: Static holding time: 185 days,  1800 (25/box) and evaporation rate: 0,6 L/day

Stainless steel indexed racks that fit into corresponding locations in the vessel. Each rack has individual storage compartments that hold one Thermo Scientific™ Nalgene™ cryogenic storage box. Optional monitor provides continuous LED readout of liquid nitrogen level; activates visual and audible alarms when level falls below safe range of approximately 2,5 cm. Optional alarm also alerts operator in the event of excessive liquid nitrogen loss.
