Thermo Scientific Model 7450 CryoMed Controlled Rate Freezer
Temperature Range
-180°C to 50°C
Exterior Dimensions
31.7 x 21.2 x 20.4 in.
- Wide range from -180°C to 50°C, suitable for various freezing requirements.
- All-In-One Benchtop Unit: combines a freezing chamber, microprocessor controls, and a printer.
- Tailored freezing profiles allows customization of multiple freezing protocols.
- Monitor chamber and sample temperatures, providing real-time responsiveness.
- Alarms for open thermocouple, heater malfunction, and temperature tracking.
- Three displays monitor temperature, profile status, and allow freeze profile edits.
The Thermo Scientific Model 7450 CryoMed Controlled Rate Freezer provides precise, repeatable freezing results with a temperature range of -180°C to 50°C that protect samples from intracellular freezing for users working in research, cell and gene therapy, vaccine production, biobanking, and more. This all-in-one cryo-freezer features an integrated control system consisting of a freezing chamber, microprocessor controls, and a printer all in one benchtop unit, allowing multiple freezing profiles to be tailored for specific protocols. Chamber and sample temperatures are monitored by Type T thermocouples, which eliminate lag time and provide “real time” responsiveness. The Model 7450 CryoMed Controlled Rate Freezer also features standard alarms providing alerts to the user for open thermocouple, heater malfunction, high/low temperature limit, temperature tracking, power failure and completion of a run.
Please Note: a 22 psi, low-pressure LN2 supply tank is required for operation and is NOT included
All of our equipment is fully tested to perform at factory specifications before being shipped.
The Thermo Scientific Model 7450 CryoMed Controlled Rate Freezer includes:
- > Power Cord
- > Operator's Manual
- > Full 180 Day Parts and Labor Warranty

- 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.
