Laboratory freeze dryer FD-18-FT-105DL

processfor the pharmaceutical industrystainless steel

Product overview
FD-18-FT-105DL laboratory continuous sublimation freeze dryer with a minimum cold-trap temperature of −105°C is designed for preservation of bacterial, fungal, polypeptide and microbial samples. The unit ships standard with 24 rubber sealing valves allowing 24 wide-mouth bottles in double rows or 24 eggplant-shaped bottles per manifold; customization available for specific needs. Key operational benefits include extended shelf stability of samples, low variability between cycles and suitability for scaled-up sample processing.

Operation and application
The highly automated system supports continuous alternating defrost and provides 48 manifold positions to reduce instrument downtime. It is suited to open-laboratory sample handling and high-throughput small-molecule synthesis workflows, enabling large-batch processing and improved operational throughput.

Features of Continuous Sublimation Freeze Dryer

• Integrated compact structure with no external flanges for simplified installation and minimized leak risk.
• All product-contact materials are inert and compliant with GLP requirements.
• Cold trap and work surface fabricated from stainless steel for corrosion resistance and ease of cleaning.
• All stainless-steel gas fill/drain valves designed in-house for corrosion resistance and leak-tight performance.
• Gas guidance system engineered to ensure uniform ice capture across the cold trap and high condensation efficiency.
• High-efficiency, energy-saving compressor for stable cooling performance and low noise.
• High-capacity vacuum pump delivering elevated pumping speed and low ultimate pressure.
• Industrial-grade embedded FD-LAB control system for reliable, stable operation.
• Intelligent data recording with historical curve query and USB export for traceability.
• LCD display and recording for cold trap temperature, sample temperature and vacuum curves; data exportable for computer review and printing.
