Thermo Fisher Scientific - Thermo Scientific Revco UXF300 UXF Freezer

• Long-term preservation of biological samples such as DNA, RNA, proteins, and cell lines.
• Storage of critical reagents, enzymes, and pharmaceutical compounds requiring ultra-low temperatures.
• Cryopreservation of tissues and organs in research and clinical settings.
• Holding temperature-sensitive vaccines and diagnostic kits.
• Use in academic research laboratories, biotech firms, and pharmaceutical manufacturing.

Typical capacity

Units in this class commonly offer internal volumes ranging from approximately 300 to 700 litres.

Temperature range

Ultra-low freezers are typically designed to maintain temperatures down to -86°C.

Power supply

For this class of equipment, a 230V, 50Hz single-phase supply is commonly required in the UK.

Footprint

Upright models like the UXF300 typically feature a compact footprint relative to their internal storage volume, suitable for laboratory environments.

Insulation

Advanced insulation, often vacuum insulation panels (VIP) or high-density foam, is standard to maximise storage density and thermal efficiency.

Door configuration

Commonly features a single outer door with multiple insulated inner doors to minimise temperature loss during access.

Control system

Modern units typically include a touch-screen interface for settings adjustment, monitoring, and data logging.

Data logging

Extensive on-board data storage for temperature and event logs, often with USB export capabilities, is a common feature.
