Unity Global Research Lyophilizer With Auto Stoppering
An in-situ freeze dryer that completes pre-freezing and drying in the same chamber, eliminating material transfer between stages. Prevents contamination, fully automates sublimation and drying, and stores lyophilization curves with USB export for process monitoring.
Applicable to the lyophilization of bulk conventional substances: liquid, paste, and solid.
Key Features
Design & Visibility
- In-situ pre-freezing and drying in a single chamber
- Colorless transparent acrylic chamber door for full-process observation
- Safety diaphragm gas charging and water draining valve, connectable to inert gas source for post-drying backfill and extended shelf life
Performance
- Professional gas diversion technology for uniform ice trapping and high ice-trapping capacity
- International-brand compressor: high efficiency, energy saving, long service life, low noise
- Fuzzy control for shelf temperature, giving minimal shelf-to-shelf variance, high precision, and uniform drying
Process Control
- Programmable lyophilization curve control: cooling rate during pre-freezing, sample heating rate during sublimation and desorption, with optional vacuum adjustment system
- FD-EMB control system stores hundreds of recipes, each with 50 temperature control sections
- Manual mode for process development, automatic mode for production
- Sensor calibration function maintains measurement accuracy over long-term use
Interface & Data
- 7-inch true-color industrial embedded touchscreen with SH-HPSC-II modular controller
- Intelligent data recording: real-time cold trap temperature, sample temperature, and vacuum curves
- USB export for computer viewing, printing, and processing
- Real-time and historical alarm logging for fault diagnosis and maintenance
- User levels and password protection for tiered access control
