Christ Alpha 1-4/2-4 LSCApplication areas of advanced laboratory freeze dryers:
Freeze drying is mainly used for drying heat sensitive and heat prone substances, such as serum, vaccines, microorganisms, tissues and other biological samples, which can maintain the original shape and structure of the samples and facilitate storage; It can also be applied to substances with a larger specific surface area, such as nanoscale particulate matter, which can maximize the preservation of the sample's surface area.

Christ Alpha 1-4/2-4 LSCConfiguration characteristics of advanced laboratory freeze dryer:
1. Process A: One layer of controllable temperature shelf, Ø 200mm, area 0.031m2, one layer of controllable temperature capping device, Ø 200mm, area 0.031m2
2. Choose a stacked drying chamber with up to 24 independently controlled external interfaces for connecting round bottom flasks, wide mouth filter bottles, and ampoule dispensers (15 interfaces)
3. Optional multi manifold with 8 rubber valve external interfaces, used to connect round bottom flasks, wide mouth filter bottles, and ampoule dispensers
4. Optional 10 layer heatable shelves, Ø 200mm, area 0.31m2, shelf spacing 25mm, optional 12 independently controlled external interfaces
5. Optional four layer capping device, Ø 250mm, area 0.18m2, shelf spacing 50mm
6. Optional five layer shelf, Ø 375mm, area 0.55m2, shelf spacing 67mm
7. Optional electric organic glass drying chamber lifting device, slowly control start/stop, achieve smooth lifting/lowering
8. Optional anti-corrosion design extension

Controller features:
In addition to the characteristics of LD Plus, the LSC controller also has the following features:
1. 1/4 VGA (Video Graphic Array) LCD large screen display, graphical user interface, with single key shuttle function, visually displays the working status of the freeze dryer and vacuum system (if in operation, it is filled)
2. It can display and control parameters such as step status, step time, shelf temperature, vacuum degree, safety pressure, heating rate, etc,
3. Accurately control every detail of the entire freeze-drying process and achieve automatic switching between each stage of freeze-drying
4. The freeze-drying process can be fully manually controlled, and the time cannot be set
5. The optional Lyocontrol LC-1 eutectic point testing system can record the temperature and resistance changes of the sample throughout the entire freeze-drying process to determine the eutectic point of the sample, thereby determining the freeze-drying process parameters, optimizing freeze-drying conditions, and improving freeze-drying efficiency. These data can also be integrated into automatic pressure control
6. Optional program module PGM-30, as a functional extension of the LSC controller, can program up to 30 drying programs, dividing the entire freeze-drying process into 15 steps and providing more step control for each stage. It can quickly import, edit, save, and delete programs
7. By setting the Delta-t between the shelf temperature and the sample temperature, better control of the freeze-drying process can be achieved
8. Information that can prompt and record erroneous operations
9. Automatic endpoint control can be achieved by equipping an electric intermediate valve (process B)
10. Optional process control system LPC-32 LSC, which enables data transmission and computer monitoring between the computer and the freeze dryer
