floor standing freeze dryer for serums and antibodies

Features of Floor-Standing Freeze Dryer

1. Intelligent control system: equipped with 7-inch LCD touch screen and PLC programmable controller to realize humanized operation and multi-stage freeze-drying program control, compatible with software upgrade.
2. Data management system: real-time display and recording of temperature, vacuum and other key parameters, can store 1000 freeze-drying curves and alarm information, support for historical data retrospective.
3. Multi-layer authority management: the system supports three levels of account control, layered authorization operation, to protect the process formula security.
4. High performance and low noise design: imported silent compressor, smooth operation, high cooling efficiency, both energy efficiency and environmental protection.
5. Intelligent alarm and diagnosis: with refrigeration system fault self-test, vacuum overrun alarm, vacuum pump maintenance tips and other active safety mechanisms.
6. Precision vacuum monitoring: Pirani vacuum gauge monitoring accuracy of 0.01Pa, to ensure that the drying process is fine and controllable.
7. Support the expansion of optional: optional oil mist filter, anti-oil return device, automatic defrost module, water vapor filter, dust filter, etc., to meet the needs of multiple scenarios.

Technical Advantages

1. Maintaining biological activity: The low temperature and vacuum environment in the freeze-drying process prevent protein denaturation and degradation of other biomolecules.
2. Sublimation drying technology: Sublimation dehydration method is adopted to make the substance directly transfer from solid state to gas state, which dramatically reduces the moisture content without liquid phase damage.
3. Quick start and modularized operation: support independent start and stop of components, improve the flexibility of equipment operation and maintenance convenience.
4. Multi-cavity design: Users can choose different types of cavities according to their needs, supporting a variety of bottles, a variety of uses, to enhance the versatility and adaptability.

Working Principle

1. Pre-cooling and freezing: the material is rapidly frozen to low temperature, so that the moisture crystallization.
2. Primary drying, sublimation drying: in a high vacuum state, through the heating of ice crystals directly sublimated into water vapor, the vapor is captured by the cold trap, removing most of the water.
3. Second drying, resolution drying: Continuous heating at a higher temperature to remove the residual adsorbed water in the material to achieve the drying effect.

The whole process ensures that the moisture is removed without damaging the thermal sensitivity or structural integrity of the sample.

Application Fields

1. Biomedicine: Preservation of vaccines, antibodies, plasma, proteins, peptides, biological enzymes and other high-value preparations.
2. Research development: Sample validation and process amplification in process development laboratories of pharmaceutical factories and scientific research institutes.
3. Medical testing: used to preserve various biochemical reagents, diagnostic test strips, biological samples and so on.
4. Food industry: freeze-dried fruits, flavored powder, instant drinks, pet food and other non-additive preservation.
5. Agricultural research: long-term preservation of plant samples, strain bank, animal vaccines, etc.

Optional Chamber Types of Floor-Standing Freeze Dryer

1. Standard type: suitable for basic sample freeze-drying treatment, without additional interface or gland function.
2. Capping type: corking and capping the vials under vacuum environment to maintain sterile sealing, suitable for pharmaceutical terminal packaging.
3. Manifold type: with manifold interface, it can handle multiple bottle types for external lyophilization at the same time, with high flexibility.
4. Capping + Manifold: Combined with the above functions, it can meet the needs of complex and diversified sample processing.
