Scientific offers advanced LyoPro series freeze-drying system with unique LyoSmart operationg system, realizing full contorl of vacuum degree, making the freeze-drying process simpler, faster and better.
LyoPro series freeze dyers are compact in design, high-efficiency in performance, smart in operation, and in daily us
Innovative features
- Compact, high-performance laboratory systems with a small footprint
- 7” touch screen installed with LyoSmart operating system
- Programmable freeze-drying steps
- Controlled vacuum degree for optimized process times
- Built-in ice condenser coils for higher efficiency
- Fast defrost via integrated hot gas
- Automatic non-return venting valve, prevents “vacuum pump" oil mist from entering cold trap
- Pirani vacuum sensor with accuracy 0.001 mbar
- Low noise level: 48~52dB(A)
- High quality vacuum pump
LyoSmart operating system
7” touch screen controller, installed with advanced LyoSmart operating system, assisting users to optimize the freeze-drying process.
- Display of ice condenser temperature and vacuum degree
- Product temperature display according to sublimation pressure curve
- Manual or automatic mode process optional
- Programmable freeze-drying steps with high flexibility
- Vacuum degree of each step can be set and controlled independently
- Historical data recorder for convenient analysis of processing
- Password access protection

Full vacuum degree control
- The vacuum degree and duration of each step can be set and controlled at auto mode
- Vacuum control to reduce drying times by up to 40%
- Real-time vacuum degree is displayed on the screen
- Pirani vacuum gauge with accuracy 0.001 mbar
Various “one button” mode
- One-button start: in auto mode, press "START" to start process according to preset program
- One-button stop: vacuum valve shut off, preventing product polluted due to vacuum back suction of pump oil
- One-button vent: aeration valve controls vacuum vent gradually, preventing product polluted due to vacuum back suction of pump oil
- One-button defrosting: hot air defrosting of cold trap, to enter a new process faster
Advanced cooling system
- -55°C: single compressor system, high efficiency
- -85°C: 2-compressor cascade system, cold trap temperature reaches -85°C within 10 minutes
- -105°C: 2-compressor cascade system, suitable for organic solvents
- SECOP brand compressor for durable use
Optimized flange seal
- Flat surface & L-shaped sealing ring design, no need for extra manual pressure
- Vacuum grease not required, easier to use and clean
- Proven excellent sealing performance for long-term use
