Testing
This Thermo Scientific TSX2320FA is used and reconditioned. Our technicians verify the accuracy of temperature controls and readouts of all freezers, making sure that the units hold temperature to within the manufacturer specified tolerance. We replace any hardware or parts as is necessary and if needed replace refrigerant. We clean all freezers thoroughly prior to shipment.

Why Choose a Refurbished TSX2320FA from American Instrument Exchange?
Purchasing a used and refurbished laboratory freezer from American Instrument Exchange offers the performance of a premium lab freezer at a significantly lower cost—without compromising reliability. Each unit undergoes a comprehensive refurbishment and validation process, including:
Testing with traceable temperature probes
Verification of temperature stability and uniformity
Inspection and replacement of critical components (gaskets, sensors, compressors if needed)
Full mechanical, electrical, and safety testing
Thorough cleaning and decontamination
Every freezer is delivered lab-ready and backed by a 90-day warranty, giving you confidence in both performance and value.
Thermo Scientific TSX2320FA laboratory-grade -20°C upright freezers are for storage of biological samples, enzymes and reagents, and clinical and diagnostic materials. It is optimized for temperature-sensitive applications requiring stable -20°C storage, with a total operating range of -25°C to -15°C, with a factory setpoint of -20°C.
What kind of compressor and cooling technology does it use?
This model uses V-drive variable-speed compressor technology that continuously adjusts compressor speed based on user patterns (like door openings), which helps maintain uniform temperatures and save energy
V-Drive” is shorthand for “Variable Drive” technology. Thermo designed a cooling system that dynamically adjusts the compressor speed, meaning that the system can ramp up cooling when a door is opened and temperature recovery is needed quickly.
Once temperature recovery is achieved and the temp of the chamber has stabilized, the compressor speed slows. This ensures both temperature stability and energy efficient operation. Thermo TSX series refrigerators, freezers, and ultralow freezers all feature V-Drive technology.
Is the Thermo TSX2320FA frost-free?
No. The TSX2320FA is a manual defrost freezer, so frost will accumulate over time and regular defrosting is required. For most labs, manual defrosting 1–2 times per year is recommended under normal lab conditions, with more frequent defrosting needed in high-humidity or high-access environments. Manual defrost helps maintain efficiency and temperature stability.
Why choose a manual defrost freezer over auto-defrost?
Manual defrost systems like the Thermo TSX2320FA avoid periodic warming cycles that are a feature of auto-defrost models, and provide better temperature consistency for sensitive samples.
