Labotemp Small Freeze Dryer LFD-301 delivers reliable lyophilization for pharmaceutical, biotechnology, food, and research laboratories handling heat-sensitive samples. Designed as a compact benchtop freeze dryer, it combines an -88°C cold trap, 0.1 m² freeze-drying area, 40 L chamber capacity, and 11 L cold trap capacity to achieve efficient moisture removal while preserving sample structure and biological activity. With a shelf temperature range of -60°C to +70°C, ±2°C temperature accuracy, ≤0.1 Pa ultimate vacuum, and up to 3 kg/24 h water trapping efficiency, the system provides stable and repeatable freeze-drying performance for biological specimens, enzymes, pharmaceuticals, plant extracts, and laboratory chemicals.
Built for dependable daily operation, the LFD-301 features a 7-inch touchscreen PLC controller with programmable drying cycles, real-time monitoring of vacuum and temperature, data logging, and USB export for complete process traceability. The in-situ freeze-drying chamber eliminates sample transfer, reducing contamination risk, while automatic cold trap defrosting, intelligent diagnostics, audible alarms, vacuum protection, and an energy-efficient refrigeration system enhance operational safety and long-term reliability.
