-50℃~50℃ Lab Vacuum Freeze Dryer Lyophilizer Top Press Freezing Drying Machine

Description: Introduction Vacuum freeze drying is the removal of water or other solvents from the frozen samples. During the whole drying process, the sample is in liquid state and the temperature is generally lower than -10. The purpose of vacuum freeze drying is to restore the original characteristics of the sample after rehydration. Because the drying process is carried out at low temperature, it can be used for some materials such as proteins, which are easy to be denatured at high temperature, and can ensure that the properties of other compounds will not change. Most of the biological products, such as tissues, tissue extracts, bacteria, vaccines and serum, were changed into dry samples by vacuum freeze-drying. Vacuum freeze drying is the most gentle process to preserve the biochemical propertie-50℃~50℃ Lab Vacuum Freeze Dryer Lyophilizer Top Press Freezing Drying MachineThe application area of this unit extends from routine drying operations to process optimisation tasks. This unit is suitable for drying solid or liquid, mainly aqueous products in vials, ampoules, tubes, other glass containers or dishes. The shelf made by sus 304 and heat exchange via silicon oil as medium ,it enable shelf temperature uniform and temperature control stability. Features:◎ Plate pre-freezing function ◎ Rising and cooling are controlled by silicone oil, and the temperature uniformity of the plate is high. ◎ Freeze-drying automatic control system: programmable programming, from freeze-drying to defrost are programmed control. ◎ Pulse backfilling system: slow, medium and fast backfilling modes can be selected to avoid the problem of effective substances being blown away by aeration of granular and flocculent substances after the end of freeze-drying. ◎ Freeze-drying curve optimization control algorithm can control the sample heating rate and the current stage vacuum value in the sublimation and analytical drying stage. ◎ Automatic drainage system: After drainage, it interlocks with the vacuum system to avoid vacuum system failure caused by forgetting to close the drainage valve. ◎ Manual automatic mode selection: manual mode is used to explore the process parameters (human intervention is strong), automatic mode is used in the mature stage of the process, one-click operation, simple and convenient. ◎ Data recording system: multiple options for data recording system ◎ Calibration function: temperature and vacuum degree calibration can be carried out to ensure the accuracy of measurement values for long-term use. ◎ Freeze-drying curve query function: can query the temperature and vacuum degree curve, convenient process optimization and freeze-drying effect verification.PaymentDelivery detailsTerms of salesAbout usContact usPaymentPayment should be completed within 4 (Four) days of auction closing.
