Thermo Scientific Locator 4 Cryogenic Storage System with Level Monitor and Vacuum Insulation

The Thermo Scientific Locator 4 is a high-capacity cryogenic storage system designed for secure long-term preservation of biological samples in molecular diagnostics, synthetic biology, and bioprocessing research. Key technical specifications include:

• LN2 capacity of 111 liters providing an ultra-low temperature environment below -180°C for critical cryostorage.
• Storage capacity for up to 3,600 cryogenic vials organized on four stainless steel indexed racks, ensuring efficient sample management.
• Exceptional static holding time of 112 days with a low evaporation rate of 0.99 L/day, leveraging vacuum insulation to minimize LN2 loss.
• Constructed with a durable vacuum-insulated Dewar design (22 in diameter × 35.5 in height, 8.5 in neck diameter), supporting stable cryogenic conditions essential for live-cell preservation and synthetic biology workflows.
• Electrical operation at 120V supports integrated level monitoring, providing critical real-time liquid nitrogen level data to secure sample integrity.
• Weighing 115 lbs (51.7 kg), the Locator 4 balances portability with robust construction suitable for biotechnology labs and biomanufacturing facilities requiring reliable cryogenic storage solutions.

This system is widely adopted in biomedical engineering, molecular biology, and clinical diagnostics for preserving DNA/RNA samples, cell cultures, and enzymes. Its design addresses the demanding requirements of biopharmaceutical production pipelines and molecular cloning workflows, ensuring sample viability over extended periods. Please note: boxes and vials are sold separately.

The Locator 4's vacuum-insulated cryogenic storage and extended static holding time make it an indispensable tool in research domains focused on gene editing, synthetic biology, and molecular diagnostics, supporting critical biotechnology and clinical research applications.
