Features of fevik lyophilizer in Germany:

　　☆The water capture capacity is 6kg / 24h, and the cold trap temperature is - 60 ℃ and - 86 ℃. There is no fluorine environmental protection refrigerant；

　　☆High vacuum professional brazing technology, Pirani vacuum gauge, vacuum display range of 1000-0.0001 mbar, wide range, high precision;

　　☆HTS controller：

　　-5-inch LCD interface and HTS operating system；

　　-The main interface clearly displays all the main process parameters, such as the temperature of condensing chamber, freeze-drying process time, segmentation time and vacuum degree；

　　-One button automatic operation, simple and convenient. It can also be run by editing program to produce freeze-drying curve；

　　-Vacuum can be controlled by pressure control valve；

　　-Maintenance setting reminder, regularly remind users to maintain the vacuum pump and main engine；

　　-Multiple security guarantees, automatic detection of faults and reminders；

-Preset the corresponding relationship table of steam pressure and temperature, through which the corresponding information of temperature and steam pressure can be inquired, and the user can set the appropriate freeze-drying vacuum degree.

　　☆316L stainless steel cold trap chamber and condenser coil, all Teflon coating. The coil is built into the cold trap to completely avoid the influence of moisture on the peripheral equipment；

　　☆Double anti oil return measures ensure that the equipment and samples are not polluted and damaged by vacuum pump return oil；

　　☆Dust filtering device between main engine and vacuum pump can prevent freeze-dried small particles from entering vacuum pump and causing damage；

　　☆The large opening design of cold trap is conducive to capture the sublimated steam quickly by the condensing coil；

　　☆Special valve for inert gas injection can effectively control the amount of injected gas；

　　☆Manual and automatic pressure relief methods fully ensure the safety of sample and sensor；

　　☆The all black coating on the shelf is beneficial to heat absorption and accelerate the sublimation process of the sample；

　　☆Design of special shelf for centrifugal tube sample placement；

　　☆Freeze drying process and curve real-time record, freeze-drying end-point judgment system, remote monitoring system；

　　☆Defrosting of refrigerant reversing operation mode；

　　☆Liquid humidity alarm interlock device of drain pipe, locking the opening function of vacuum pump。
