The Labconco FreeZone 4.5L -105C Benchtop Freeze Dryer System is designed for lyophilizing light to moderate sample loads in laboratories with limited space. This compact unit effectively removes up to 2.5 liters of water over 24 hours and operates at a low temperature of -105°C (-157°F) at 60 Hz, making it suitable for processing low eutectic point substances like acetonitrile, dilute methanol, and ethanol. The system includes an upright stainless steel collector coil capable of holding 4.5 liters of ice before defrosting and features a durable stainless steel lid with a neoprene gasket. Equipped with the Lyo-Works™ OS on a 5-inch full-color capacitive touchscreen, it provides real-time displays of collector temperature and vacuum levels, with optional End-Zone™ end point detection. The dryer's exterior combines brushed stainless steel with a glacier white, powder-coated steel with blue accents. Additional functionalities include data logging capabilities exportable via USB or Ethernet, programmable alerts, and maintenance reminders—all controllable through an intuitive interface that supports multiple languages. Safety features such as a moisture sensor, vacuum control valve, and an automatic restart after short power outages ensure reliable operation.
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.
