Pro-8085 shelf type laboratory freeze-drying machine Introduction: The typical freeze-drying process can be divided into three stages: freezing, primary drying, and secondary drying. In a properly controlled freeze-drying process, the product temperature must be kept sufficiently low throughout the entire process to prevent structural changes in the dried product matrix, which can have a negative impact on the appearance and properties of the final product. In response to higher requirements for sample processing, the Pro series professional laboratory freeze-drying machine has developed a professional Lyo S operating system, which realizes a series of functions such as vacuum control, sample temperature simulation, main drying and secondary drying program operation, etc., making the equipment have higher intelligent performance and making freeze-drying samples easier and more controllable. characteristic: 1. High precision sensor for more accurate data -0.001-1000mbar High precision Pirani sensor with adjustable and controllable full range vacuum degree, avoiding sample problems such as foaming, bottle blowing, and ice nucleation caused by uncontrollable vacuum, and accelerating freeze-drying speed through reasonable vacuum control; 2. Advanced refrigeration system for faster cooling - extremely fast cooling, significantly reducing sample preparation time. 3. Dual solenoid valves for more precise vacuum control - vacuum control and pressure relief are independently controlled, enabling precise control of vacuum degree. The system indirectly controls the surface sublimation temperature of the sample through the saturation vapor pressure curve of water. 4. Sample temperature simulation, intelligent recommendation of the best freeze-drying conditions - software fits the ice water saturation vapor pressure curve, and the equipment simulates the interface sublimation temperature of the sample during the freeze-drying process. Compared with the ineffective design of traditional laboratory temperature probes that cannot insert samples that have already frozen solids, this software more intuitively simulates the temperature parameters of the sample during sublimation and realizes the control and adjustment of the sample temperature, which is more practical and convenient; 5. Freeze drying program, freeze-drying plan can be set according to your preferences - the equipment can set the freeze-drying program, set the system preheating, main drying, and secondary drying to be carried out in steps, independently set the vacuum degree and corresponding duration for each step to ensure the freeze-drying efficiency and effect of the sample. The program can also be started with just one click, which is convenient and fast. 6. Automatic pressure relief, more reassuring for samples - stable air intake rate, protecting sample integrity, can be filled with inert gas, providing an oxygen free and clean environment. 7. The equipment is equipped with a pressure protection device, making it more reliable to use - when the ambient temperature of the equipment is too high, the protection device starts to protect the equipment, avoiding damage caused by high-pressure operation; 8. One click defrosting, simpler operation - can be started with one click after the experiment, automatically heating the cold trap coil to quickly remove ice from the cold trap; 9. Operator password permissions for safer instruments - Strengthen the management of the use of freeze-drying machines; Record the running time, maintenance time, and pump oil replacement time of the equipment for easy maintenance and upkeep; Technical parameters: Number of partition layers: optional 3-4 layers or more 55/5/105 Freeze dried area: 0.16m ² -0.32m ² Divider size: diameter of 260mm Ice coagulation efficiency: 8Kg/24h Maximum freezing capacity: 12Kg Extreme vacuum degree: 0.01mbar/1pa Vacuum control range: 0.01-1000mbar Host size: W900 * D720 * H1300 mm Host weight: 130Kg Host power: 2KW Power requirements: 16A, 220V
