Thermo Scientific Revco UGL2320A20 -20C Lab Freezer

The Thermo Scientific Revco UGL2320A20 is a high-performance laboratory freezer, specifically designed to meet the rigorous storage requirements of medical and scientific applications. This unit is ideal for preserving a variety of laboratory materials including reagents, pharmaceuticals, biologicals, primers, and more. With a preset temperature of -20°C and a spacious 23.3 cubic feet (659L) capacity, it ensures optimal storage conditions. Key features of the Revco UGL2320A20 include manual defrost control for precise temperature management, and an efficient cold wall convection cooling system that maintains uniform temperature distribution. The freezer is equipped with adjustable, epoxy-coated wire shelves, with the option of drawers, ensuring versatile storage solutions. Safety and security are enhanced by a keyed on/off switch with setpoint security, a self-closing door with a 90° stop position, and built-in remote alarm contacts.

User convenience is addressed through its icon-based control panel and a large, easy-to-read digital display that shows temperature variations within 1°C. The graphic thermometer indicator provides visual alerts for overtemperature and under-temperature conditions. Additional features include audible/visual warnings, a push-button alarm test, and a controller battery backup system. The freezer's construction is robust, featuring scratch-resistant cold-rolled steel interior and exterior finishes, and high-density, 2-inch-thick CFC-free urethane foam insulation, which guards against ambient temperature fluctuations. The CFC-free, HFC-blend refrigerant is environmentally friendly. The unit stands on four casters for easy mobility, with the front two being lockable. This model is particularly suitable for applications where slight intermittent coil warming during an automatic defrost cycle is not desirable, such as enzyme storage. Its gravity convection air system provides maximum stability without the need for a blower or fan.

All of our equipment is fully tested to perform at factory specifications before being shipped.

Recertification Inspection Protocol

Inspect the display for pixel clarity and brightness, replacing any dim or dead pixels.
Test all buttons for responsiveness, resistance, and durability; replace any that don’t meet standards.
Check the door seal and lock for airtightness, replacing any compromised components.
Run diagnostics on PCB test points for voltage and current accuracy, replacing faulty components.
Verify compressor output and airflow, ensuring all internal fans function properly.
Cross-check internal temperature probe accuracy with a NIST-traceable probe, recalibrating if needed.
Inspect wiring for frays or tears, replacing compromised sections as necessary.
Test the start capacitor's capacitance and replace if it’s outside the specified range.
Replace all internal filters and thoroughly clean condenser fins for efficient heat dissipation.
Verify the alarm battery holds a full charge and replace if there is any degradation.
Operate the unit for 72 hours to confirm stable temperatures and operational consistency.
Perform a final cosmetic check, repairing or touching up surfaces as needed for a professional appearance.
