Multi-Manifold "TOP" Type Vacuum Freeze Dryer
All-in-one structure , small size, no external flange, easy to use, no leakage
"TOP" model freeze dryer, suitable for laboratory freeze-drying experiments and small-scale production.
Combines the features of the pressure cover type and the regular type with multiple manifolds.
Equipped with 3 layers of stainless steel trays with adjustable spacing.
It is suitable not only for the freeze-drying of bulk (liquid, paste, solid) conventional materials but also for the drying of materials in vials.
During freeze-drying preparation, materials can be divided into vials as needed, sealed with caps, and then subjected to freeze-drying.
After drying, the pressure cover device can be used to move and seal the vials in a vacuum state, making them suitable for long-term storage.
The external attachment is independent of the drying process and can be disassembled at any time. It can be used in conjunction with a concentrator to achieve both freeze-drying and concentration.
It belongs to a series of benchtop basic freeze dryers widely used in the medical, pharmaceutical, biological, chemical, and food sectors.
Designed for laboratory use, they meet the requirements of most routine freeze-drying operations.
Thanks to their compact dimensions, ease of use, and excellent cost-performance ratio, these freeze dryers represent an efficient and competitively priced solution for the preservation of samples and products.
They are essential tools for professionals requiring reliable, reproducible, and repeatable freeze-drying processes.
Instrument Advantages
- Integrated design – Compact, leak-free, and user-friendly structure with no external flanges. The reduced footprint makes it suitable for any laboratory environment. The system is designed as a monoblock unit, requiring no complex installation.
- GLP-compliant materials – All materials in contact with the product are inert and fully compliant with GLP requirements, ensuring reliable and accurate experimental results even for demanding laboratory protocols.
- Highly corrosion-resistant structure – The cold trap and work surface are made of stainless steel, offering excellent corrosion resistance and easy cleaning, extending equipment lifespan and reducing maintenance costs.
- Safety valves – Stainless steel gas inlet valves, internally designed and manufactured, ensure safety, corrosion resistance, and eliminate the risk of leakage.
- Advanced pre-freezing function – Large cold trap opening and integrated sample pre-freezing function, eliminating the need for a separate low-temperature freezer.
- Gas flow control technology – Dedicated technology that ensures uniform ice capture within the cold trap, improving efficiency and overall freeze-drying performance.
- Efficient and energy-saving compressor and vacuum pump – The system is equipped with highly reliable compressors and vacuum pumps, characterized by high efficiency, long service life, and low noise levels.
- Modular control system – Next-generation modular controller with advanced control logic, ensuring process reliability and repeatability. High-resolution 7-inch LCD touchscreen, intuitive and easy to operate even for non-expert users.
- Intelligent data logging system – Real-time recording and display of cold trap temperature, sample temperature, and vacuum level curves. Data can be easily exported to a computer for consultation, processing, printing, and advanced data management.
- Intuitive user interface – Human–machine interface with real-time system status display, English language support, selectable vacuum units, and a comprehensive alarm system (high ambient temperature, vacuum pump oil change, operating time, sensor faults, compressor and pump status, general non-compliances, etc.).
- Comprehensive system protection – Includes delayed compressor start protection, overload and short-circuit protection for both compressor and vacuum pump, ensuring operator and equipment safety.
- Intelligent electric defrosting – Low-voltage electric defrosting system, safe and highly efficient, significantly improving defrosting performance while reducing maintenance costs.
