Ultra Low Temperature Freezer Model 528 / 352 with Digital Control and VIP Insulation

The Ultra Low Temperature Freezer (ULT) series models 528 and 352 offer specialized cryogenic storage solutions optimized for biotechnology and clinical diagnostics laboratories. Featuring an adjustable shelving system within rustproof stainless-steel chambers, these freezers support high-capacity storage of 528 or 352 2-inch cryoboxes respectively, essential for bioprocessing and molecular diagnostics workflows.

Key specifications include:

• Temperature range: −86°C to −50°C, critical for preserving sensitive biological samples and reagents.
• Internal volumes: 700 L (24.7 cu ft) for model 528 and 500 L (17.7 cu ft) for model 352 enable flexible storage configurations.
• Exterior dimensions: 49x40x78 inches (528) and 37x40x78 inches (352), suitable for laboratory environments.
• Weight: 700 lbs (528) and 574 lbs (352).
• Power requirements: 115V, 60Hz, 1.40kW with Energy Star certification, using climate-friendly refrigerants with Vacuum Insulation Panels (VIP) for reduced energy consumption and heat emission.
• Features: Digital temperature control with real-time monitoring, programmable setpoints, data retrieval via USB or Ethernet interfaces, and extended power failure warm-up time averaging 360 minutes to −50°C, ensuring sample integrity in critical conditions.

These freezers are widely adopted in synthetic biology research and biopharmaceutical production pipelines due to their reliability and energy efficiency. Their design minimizes temperature fluctuations during sample access via dual-compartment doors, enhancing sample preservation for live-cell imaging, fluorescence studies, and molecular cloning applications. This equipment is critical in any laboratory requiring stable, ultra-low temperature environments for long-term storage in biotechnology and clinical research domains.
