EYELA FDU-2200 Laboratory Freeze Dryer with Digital Vacuum and Refrigerated Trap

The EYELA FDU-2200 Laboratory Freeze Dryer is engineered for advanced biotechnology and molecular diagnostic applications requiring precise lyophilization and moisture removal. Featuring a -80°C refrigerated trap, this freeze dryer ensures efficient sublimation for biomolecule preservation and bioprocessing workflows. Key technical characteristics include:

• Digital vacuum system with Pirani gauge (0–533 Pa) enabling real-time vacuum degree monitoring critical for reliable freeze-drying cycles.
• Hot gas defrost trap system prevents ice buildup to maintain consistent performance.
• Safety mechanisms such as leakage and overcurrent breakers, compressor protection circuit, and control board self-diagnosis secure instrument integrity.
• Vacuum pump operation automation and vacuum release valve enhance operational ease and cycle reproducibility, essential for molecular cloning and synthetic biology research requiring repeatable freeze-drying protocols.
• Dual air-cooled compressors (2×500W) utilizing R404A and R23 refrigerants provide robust cooling capacity.
• The vacuum pump is optional but recommended to meet a minimum exhaust capacity of 50 L/min for optimal drying efficiency.
• Compact dimensions (approx. 45 × 55 × 93.5 cm) and 67 kg weight make it suitable for benchtop laboratory environments with space constraints.

This freeze drying system supports research and development pipelines in biotechnology, biomedical engineering, and pharmaceutical biomanufacturing, facilitating sample stabilization critical in molecular diagnostics and gene editing workflows. The unit is currently offered as used and sold as-is, with performance not guaranteed to fully match new equipment conditions.

This freeze dryer is essential for laboratories conducting freeze drying in synthetic biology, bioprocessing, or clinical diagnostics, ensuring controlled dehydration without compromising biological activity.
