FD-1A-50+ Vacuum Freeze Dryer – Standard Bulk-Sample Configuration

Product Introduction
The FD-1A-50+ Vacuum Freeze Dryer is a laboratory freeze-drying system designed for removing moisture from suitable aqueous solutions, suspensions, and paste-like materials. This model uses the standard bulk-sample configuration, making it suitable for materials placed directly on sample trays.
The FD-1-50 Plus series is available in five configurations: standard bulk-sample, stoppering, manifold, manifold with stoppering, and T-type manifold for up to 24 containers. The FD-1A-50+ standard configuration features a 0.12 m² drying area, a −55°C unloaded cold-trap temperature, and a specified drying capacity of 2 L per 24 hours.
With PLC and touchscreen control, sample temperature monitoring, freeze-drying curve storage, automatic hot-gas defrosting, and inert gas backfilling, the FD-1A-50+ supports routine laboratory sample preparation and freeze-drying process development.

Performance Features
• Integrated drying chamber: One-piece chamber construction without bonded joints, designed for high strength and reduced leakage risk.
• PLC touchscreen control: Provides convenient equipment operation and process monitoring.
• Sample temperature monitoring: Two sample temperature sensors enable real-time temperature observation.
• Freeze-drying curve recording: Displays and stores process curves for review and process optimization.
• USB data export: Supports exporting stored freeze-drying data to a USB drive.
• Pre-freezing function: The cold trap can be used for pre-freezing applications.
• Automatic hot-gas defrosting: Uses hot-gas defrost technology for efficient cold-trap defrosting.
• Low-temperature cold-trap drying: Supports specialized low-temperature cold-trap drying applications.
• Inert gas backfilling: An imported gas-filling valve supports nitrogen or other suitable inert gas introduction after drying.
• Reliable refrigeration: Uses a branded compressor designed for stable operation and low noise.
• Multiple series configurations: The FD-1-50 Plus family offers options for bulk materials, vial-based samples, and manifold-connected containers.

Working Principle
The FD-1A-50+ uses vacuum freeze-drying, also known as lyophilization, to remove moisture from frozen samples.
1. Sample preparation: Suitable material is placed on the sample trays and frozen.
2. Vacuum establishment: The vacuum pump reduces the pressure inside the drying system.
3. Sublimation: Under suitable vacuum and temperature conditions, frozen water changes directly into water vapor without passing through the liquid phase.
4. Moisture capture: The cold trap condenses and captures water vapor, helping protect the vacuum system.
5. Process monitoring: The PLC system monitors sample temperature and records freeze-drying curves.
6. Defrosting: After the process, hot-gas defrosting helps remove accumulated ice from the cold trap.
7. Protective backfilling: Nitrogen or another compatible inert gas can be introduced after drying to support sample preservation where required.
Successful freeze-drying depends on sample formulation, freezing conditions, chamber pressure, temperature settings, and the material's eutectic or collapse characteristics.

Frequently Asked Questions
Q1: What is the FD-1A-50+ vacuum freeze dryer used for?
It is designed for laboratory freeze-drying of suitable aqueous solutions, suspensions, and paste-like materials in the standard bulk-sample configuration.
Q2: What is its drying area?
The specified freeze-drying area is 0.12 m², with four sample trays measuring Ø200 mm each.
Q3: What are the cold-trap temperature and vacuum specifications?
The unloaded cold-trap temperature is −55°C, and the unloaded vacuum level is specified as below 9 Pa.
Q4: What is the stated drying capacity?
The stated capacity is 2 L per 24 hours. Actual performance depends on sample characteristics, initial moisture content, loading, and operating conditions.
Q5: Does the FD-1A-50+ support sample temperature monitoring?
Yes. It includes two sample temperature sensors for real-time temperature monitoring.
Q6: Can test data be exported?
Yes. The system stores freeze-drying data and curves and supports USB data export.
Q7: How is the cold trap defrosted?
The equipment uses hot-gas defrosting rather than conventional electric-heating defrosting.
Q8: Can nitrogen be introduced after drying?
Yes. The gas-filling valve supports nitrogen or another suitable inert gas for post-drying backfilling, subject to the sample and process requirements.
Q9: Is the FD-1A-50+ suitable for vial stoppering?
The supplied model is the standard bulk-sample configuration with manual placement on sample trays. For vial stoppering, select the corresponding stoppering or manifold-stoppering configuration in the FD-1-50 Plus series.
