Jipu Freeze Dryer, Laboratory Small-Scale Lyophilizer

Jipu LGJ-10A-50 Laboratory Small Freeze Dryer

The LGJ-10A-50 Freeze Dryer (Lyophilizer) is a compact freeze-drying device specifically designed for laboratory, R&D center, and small-batch production scenarios. This equipment employs advanced vacuum freeze-drying technology to directly sublimate moisture from aqueous materials under low-temperature and vacuum conditions, thus preserving the biological activity, chemical structure, and original form of the materials to the greatest extent. It is applicable for efficient drying and long-term preservation in fields such as biological products, pharmaceutical intermediates, food additives, enzyme preparations, microbial strains, plant extracts, and nanomaterials.

Working Principle

The freeze-drying process consists of three stages: pre-freezing, primary drying (sublimation), and secondary drying (desorption). First, the material is rapidly frozen in a cold trap to a temperature below its eutectic point, causing free water to completely freeze into ice crystals. Subsequently, the vacuum pump system reduces the system pressure to below the triple point of water, and the shelf is gradually heated, allowing the ice crystals to sublimate directly into water vapor, which is captured by the cold trap (with temperatures as low as -50°C). Finally, during the heating process, bound water is further removed, resulting in a loose, porous freeze-dried product with extremely low moisture content (typically below 1%).

Product Features and Technical Advantages

• High-Efficiency Cold Trap System: The cold trap can reach a minimum temperature of -50°C, with a water capture capacity of ≥2kg/24h, ensuring rapid condensation of water vapor during sublimation, protecting the vacuum pump from moisture damage, and enhancing drying efficiency.
• Precise Temperature and Vacuum Control: Shelf temperature control accuracy is ±1°C, with programmable multi-stage heating and cooling curves; vacuum level is automatically adjusted to maintain a constant low-pressure environment (<10Pa), meeting the personalized freeze-drying curve requirements of different materials.
• Compact Design: The unit occupies a small footprint (approximately 0.3㎡), making it easy to place on a lab bench or in a fume hood. It is equipped with a standard φ200mm × 4-layer stainless steel shelf, capable of processing 1-2L of liquid sample per batch.
• Safety Protection and Data Traceability: Features include automatic power-off protection, over-temperature alarm, vacuum failure alarm, and automatic pressure relief; an integrated touchscreen control system displays real-time cold trap temperature, shelf temperature, vacuum level, and drying time, and supports data export via USB or RS232 interface.
• Sealing and Corrosion Resistance: Utilizes silicone rubber sealing rings and aviation-grade glass observation windows. The cold trap and drying chamber are made of 304 stainless steel, offering corrosion resistance and easy cleaning, meeting laboratory hygiene standards.

Application Scenarios

This equipment is particularly suitable for scientific research institutions, university laboratories, biotechnology companies, and formulation development units. Typical applications include: freeze-drying preservation of biologically active proteins such as vaccines and antibodies; preparation of concentrated freeze-dried powders from Chinese herbal medicines and natural products; activity protection of probiotics and yeast; construction of porous structures for nanoparticles and catalysts; and microencapsulation of food flavor compounds or fragrances. Its flexible, compact design also facilitates process parameter optimization before small-scale pilot scale-up.

Choosing the LGJ-10A-50 Freeze Dryer provides you with a reliable, precise, and easy-to-operate core laboratory instrument, helping to enhance the efficiency of your R&D and quality control processes.
