Thermo Revco ULT1230 High Performance Laboratory Freezer
Many laboratories need dependable frozen storage below the capabilities of a standard -20°C laboratory freezer but don't require the complexity and operating costs of an -80°C ultra-low freezer. The Thermo Revco ULT1230 High Performance Laboratory Freezer fills that niche by providing reliable storage to -30°C in a space-saving upright cabinet designed specifically for research, pharmaceutical, and clinical laboratory applications.
With an 11.5 cubic foot (326 L) capacity, the ULT1230 is ideal for biotechnology companies, pharmaceutical manufacturers, hospitals, universities, environmental laboratories, and industrial research facilities storing plasma, biological specimens, reagents, pharmaceuticals, vaccines, and research materials requiring dependable -30°C storage. Its forced-air circulation, automatic defrost system, and high-density insulation help maintain consistent cabinet temperatures while providing rapid recovery following routine door openings.

Thermo Revco ULT1230 Overview
The ULT1230 was designed for laboratories that require dependable -30°C storage while maximizing usable laboratory space. Unlike residential freezers, it utilizes positive forced-air circulation to promote uniform temperatures throughout the cabinet, helping ensure samples remain at consistent temperatures regardless of shelf location.
Its automatic condensate removal system eliminates the need for drain lines during normal operation, while the high-density urethane insulation minimizes operating costs and protects the cabinet from ambient room temperature fluctuations. Together, these features make the ULT1230 well suited for laboratories accessing samples frequently throughout the workday.

Operating Costs & Energy Considerations
Because the ULT1230 operates at -30°C rather than -80°C, it consumes significantly less energy than a cascade ultra-low freezer while still providing dependable storage for many laboratory applications. High-density insulation, automatic condensate removal, and forced-air circulation help improve refrigeration efficiency. Routine condenser cleaning and adequate ventilation will maximize performance and extend equipment life.

Refurbishment & Testing Process
Every Thermo Revco ULT1230 received by American Instrument Exchange undergoes a comprehensive inspection and temperature performance evaluation before shipment. Our technicians verify controller accuracy, compressor operation, automatic defrost performance, airflow, refrigeration performance, door gasket integrity, and overall cabinet condition. Temperature stability is confirmed using calibrated digital temperature probes, worn components are replaced as needed, and every freezer is thoroughly cleaned prior to shipment.
The Thermo Revco ULT1230 ships by freight from American Instrument Exchange. Before installation, laboratories should verify doorway clearances, available floor space, electrical service, and adequate condenser ventilation. Allow the freezer to reach operating temperature before loading valuable materials to ensure optimal storage performance.
