DA-1S-50 Lab freeze dryer stoppering heating shelf

Lab Freeze Dryer Features

• Touch LCD display with microprocessor controller, easy to use.
• Dry chamber using aircraft grade acrylic materials, non-adhesive, high strength, and no leaks.
• Condenser pre-cooling function.
• Used DANFOSS compressor.
• Vacuum pump in Japan or Korea brand, with oil-mist filter can trapping oil mist in the exhaust gas, reduce environmental and health hazards.
• Can charge nitrogen or inert gas to save after drying.
• Programmable, freezing, drying and defrosting will be program controlled.
• Automatic control system: Temperature heating control for each shelves, heating circulation monitoring protect, fuzzy PID control algorithm.
• Defrost system: Auto Non-electric heating defrost, more safety and fast.
• Vacuum regular system: vacuum degree regular in sublimation and drying process to avoid special material foaming or blowing, accelerate lyophilized efficiency (Optional)
• Pulse backfill system: slow, medium, fast three kinds of backfilling mode selection, avoiding the granular material and flocculent material being blown out effective loss problem inflatable pro  duce. (Optional)
• Automatic drainage system: interlock with vacuum system after draining to prevent any failure in vacuum system. (Optional)
• Can be work in automatic or manual operation, manual mode is used to explore the process parameters, automatic mode for process maturity.
• Data recording system: 1) data can be stored in machine in 3 months; 2) External U-disk storage (Optional); 3) PC-database storage (Optional)
• Monitoring system: real time system temperature and vacuum degree monitored, acquisition frequency 50ms / time.
• Lyophilization process recipe storage function: can store 500 set of fixed or user-defined lyophilized formulation process.
• PC remote monitor system: remote monitor working status of machine, max 1.5km distance (Optional)
• Eutectic point test function (Optional)
• Calibration function: temperature and vacuum calibration ensures long-term accuracy of the measured values.
• Freeze-drying curve searchable.

Lab Freeze Dryer Safety Protection

• Over-current protection
• Over-load protection
• Over-heating of temperature
• Vacuum defense in processing
• 36V safety voltage for heating system
• Vacuum pump protection
