HiYi Pro-4085 Professional Laboratory Freeze Dryer

For demanding sample processing, the Pro-4055/4085 professional laboratory lyophilizers have been developed with the professional LyoS operating system, which realises a series of functions such as vacuum control, sample temperature simulation, primary drying and secondary drying program operation, making the equipment have a higher level of intelligent performance, and making lyophilized samples easier and more controllable.

• LyoS operating system ----7 inch LCD touch screen, the interface is refreshing and intuitive, you can choose two freeze-drying modes, manual control and programme control; software functions include: vacuum control function, sample freeze-drying temperature simulation curve, automatic pressure relief, hot gas defrost, automatic system preheating, automatic programme drying, etc., powerful functions, convenient operation;
•  
• Compact design ---- equipment appearance integrated structural design, compact size, simple atmosphere, appearance *, easy to clean, to save you valuable laboratory space;
• Cavity cover separation design ---- unique freeze-drying cavity compartments and cavity cover are made of different materials, the cavity is made of high-transparent acrylic, which is easy for sample observation and rapid sublimation, while the cavity cover is made of treated aluminium, which is durable. This design makes it very easy to increase the number of compartment layers and the acrylic chamber is very inexpensive to replace;
• External cold trap ---- independent external cold trap coil design, so that the low temperature of the cold trap coil directly involved in low-temperature ice trapping, avoiding the energy loss brought about by multiple heat transfers, making the cold trap temperature more real, more efficient; cold trap from room temperature to -85 degrees, it takes less than 10min, the cavity and condensing coils are equipped with Teflon corrosion treatment, can freeze-drying of organic solvents and various types of corrosive Sample
• Flange surface sealing ---- sealing surface using flat plus L-type sealing ring, to ensure the durability and stability of the sealing surface, can ensure that the equipment in the high-frequency long-time operation can also maintain a very good sealing;
• 0.001-1000mbar high-precision Pirani sensor ---- makes the experimental data more accurate and reliable; full-range vacuum adjustable and controllable, to avoid the special substances brought about by the vacuum is not controllable blistering, blowing bottles and ice nuclei and other samples of the problem, can be accelerated through a reasonable vacuum control of the freeze-drying speed.
• Vacuum control ---- double electromagnetic design, vacuum control and pressure relief separate independent control, can achieve accurate control of vacuum degree, the system through the water saturation vapour pressure curve, indirectly control the sample surface sublimation temperature.
• Sample temperature simulation software ---- software fitting ice and water saturation vapour pressure curve, the device simulates the interface sublimation temperature of the sample in the process of freeze-drying, compared with the ineffective design of the traditional laboratory temperature probe can not be inserted into the sample that has been frozen solid, the software is more intuitive to achieve the temperature parameters of the sample in the sublimation, and to achieve the control and adjustment of the sample temperature, more practical and convenient;
• Freeze-drying procedure ---- equipment can set the vacuum freeze-drying procedure, set the system preheating, main drying and secondary drying step by step, independently set the vacuum degree of each step and the corresponding time duration, to ensure that the sample freeze-drying efficiency and effect, but also can be a key to start the procedure, convenient and fast.
• One-key pressure relief function ---- can start the vacuum relief process with one key at the end of the experiment, no need to operate manually, convenient, efficient, and can realise the function of inert gas backfill after the end of freeze-drying;
• The equipment is equipped with a pressure protection device ---- When the ambient temperature of the equipment is too high, the protection device starts to protect the equipment, avoiding the damage caused by high pressure operation;
• One-key defrost function ---- can be at the end of the experiment, the equipment automatically heats the cold trap coil to quickly remove the cold trap icing;
• The operator password authority ---- can be set to strengthen the use of the freeze dryer management; equipment record running time, maintenance time and pump oil replacement time, to facilitate maintenance.

The pilot lyophiliser is widely used in biopharmaceutical, medical and food industries. For example, in the production of biological products such as BCG vaccine, influenza vaccine, measles vaccine, influenza vaccine, etc.; the production of antibiotics in the production of Western medicine, circulatory organs with drugs. In the medical field, freeze-drying technology can be used for long-term preservation of blood, arteries, bones, skin, cornea and nerve tissue and other organs.​
