Labconco 4.5L -50C Console Freeze Dry System, PTFE Coated
The Labconco FreeZone 4.5L Console Freeze Dry System, PTFE Coated (Cat. #: 7751021) is engineered for light to moderate aqueous sample loads, featuring a low temperature of -50°C and a 10-port drying chamber for efficient operation. The PTFE coated collector coil, chamber, and drying chamber are suited for processes involving corrosive compounds, and this freeze dryer can remove over 2 liters of water in 24 hours. The exterior boasts brushed stainless steel and glacier white, epoxy-coated steel with blue accents. It offers an LCD that not only displays operating and setup parameters but also alarms and maintenance schedules. Additional features include a red alarm light, LED vacuum and temperature wave graphs, and a patented moisture sensor.
The FreeZone 4.5L Console Freeze Dry System, PTFE Coated integrates a 1/3 hp CFC-free refrigeration system, vacuum control/break valves, and a rear-mounted RS-232 port for data transmission to a computer. Safety and convenience are further enhanced with automatic start-up for collector cool-down and vacuum pull-down, complemented by manual override switches. This system ensures reliability even during power outages, resuming operations automatically if the interruption is brief, while safeguarding sample integrity with its sophisticated monitoring and control mechanisms.
All of our equipment is fully tested to perform at factory specifications before being shipped.

- Inspect the display for pixel clarity and brightness issues; replace any dim or defective pixels to ensure optimal visual quality.
- Test each button for responsiveness, resistance, and continuity; replace any buttons that show wear or unresponsiveness.
- Check the acrylic/glass lid for structural integrity, looking for cracks or chips; replace if any damage is found.
- Examine all external gasket seals for elasticity, cracks, or tears; replace compromised seals with OEM-approved parts.
- Remove and replace all manifold ports with new OEM parts, ensuring proper fit and sealing to maintain system integrity.
- Drain and replace the oil, verifying the new oil’s viscosity and particulate levels fall within operational standards.
- Conduct diagnostic checks on all PCB test points, replacing any malfunctioning components to maintain circuit integrity.
- Inspect all internal rubber connections and gaskets for cracks or brittleness; replace compromised parts as needed.
- Disassemble and clean the condenser coils and fan assembly to remove dust; replace worn components to ensure efficiency.
- Confirm the start capacitor for the refrigeration system meets the manufacturer-specified capacitance range; replace if readings deviate.
- Test and calibrate all internal sensors and safety switches, ensuring accurate readings and replacing any faulty components.
- Verify displayed temperatures by cross-referencing with independent calibrated probes; recalibrate the system if discrepancies are detected.
- Check vacuum pressure using an independent gauge, aiming for ~0.40 mbar; address any leaks or inefficiencies affecting vacuum levels.
- Confirm the system achieves and maintains low temperatures (~-50°C or ~-80°C) using certified measurement tools; troubleshoot as necessary.
- Inspect all external surfaces, labels, and interfaces for cosmetic wear; address any scratches, blemishes, or visible signs of damage.
