LMFD260PL and LMFD280PL Pilot Freeze Dryers are designed for laboratory and pilot-scale lyophilization processes requiring precise control of temperature and vacuum conditions. The systems remove water from frozen samples through sublimation, preserving product structure and stability for pharmaceutical, biotechnology and research applications.
LMFD260PL features a condenser temperature of -60°C and is suitable for most aqueous solvents, while LMFD280PL offers an ultra-low condenser temperature of -80°C for low freezing point substances. Both models provide temperature, cooling, heating and vacuum control through a 7-inch touch screen interface with real-time monitoring and programmable operation.
The units are equipped with SS304 shelves and chamber construction, transparent acrylic door, hydraulic stoppering mechanism and silicone oil circulation shelf cooling. A DSVP55 vacuum pump is supplied as standard, ensuring stable vacuum generation and efficient drying performance.
