description
Vacuum freeze dryers are extensively utilized in medicine, pharmaceuticals, biological research, chemical engineering, and food processing sectors. Lyophilized products can be stored long-term with ease, and upon rehydration, they revert to their pre-freeze-dried state while retaining all original biochemical properties. The LFD-18SD is a compact vertical freeze dryer equipped with shelf heating and programmable capabilities, tailored for laboratory applications or small-scale production to fulfill the routine freeze-drying requirements of most laboratories.
features
1. Equipped with internationally renowned brand compressors, ensuring high efficiency, energy savings, extended service life, and low operational noise.
2. Incorporates well-known brand vacuum pumps with high pumping speed, enabling attainment of a superior ultimate vacuum level.
3. Features a 7-inch true-color industrial embedded touch screen paired with the SH-HPSC-II modular controller, delivering high control precision, stable and reliable performance.
4. The professionally engineered FD-EMB control system can store hundreds of process recipes, each consisting of 50 temperature control segments to enhance process optimization efficiency.
5. All product-contacting components are constructed from inert materials, fully meeting GLP requirements.
6. Both the cold trap and operation table are fabricated from stainless steel, offering excellent corrosion resistance and easy cleanability.
7. Adopts an all-in-one structural design with a compact footprint, no external flanges, ensuring straightforward operation and zero leakage.
8. Boasts a large-opening cold trap without internal coils, featuring sample pre-freezing functionality that eliminates the need for a low-temperature refrigerator.
9. Utilizes specialized gas guiding technology, enabling the cold trap to capture ice uniformly with exceptional ice-trapping capacity.
10. The shelf heating system operates at a safe voltage of 36V, with adjustable heating rate control.
11. Offers flexible manual + automatic control modes: manual mode for process exploration, automatic mode for batch production runs.
12. Includes a vacuum pump protection function, which allows setting the cold trap temperature threshold for pump startup to safeguard the vacuum pump’s service life.
13. Provides real-time alarm display and historical alarm inquiry functions, facilitating efficient fault diagnosis and equipment maintenance.
14. Integrated intelligent data recording system that real-time records and displays cold trap temperature curves, sample temperature curves, and vacuum level curves; exported data can be viewed on a computer and printed.
15. Features robust sensor calibration capabilities, ensuring accurate long-term measurement accuracy.
16. Supports user level setting and password authorization, enabling decentralized operation management.
17. Custom-designed and manufactured all-stainless steel inflation (discharge) valve, ensuring safety, corrosion resistance, and zero leakage.
