Flexible freeze drying systems for optimized processes:
Based on over 50 years of experience, Martin Christ presents a comprehensive product range covering routine applications as well as reliable equipment for individual and product specific drying processes. The newly introduced freeze dryers with LDplus- and LSC-controller set new standards for flexibility and process control. The modular accessory line allows for individual system configurations adaptable to almost every freeze-drying application. Two different drying techniques provide a solution to most lyophilisation challenges.
Your choice on two different freeze drying processes:
 |
single-Chamber-System (Process A, only for units with LSC-Controller):
Freezing and drying of low freezing and thermosensitive substances on cooled shelves (e.g. at -40°C) inside the ice condenser chamber (see figure 1)
Typical drying vessels:
- dishes
- injection vials (stoppering under vacuum or inert gas)
|
|
|
Double-Chamber-System (Process B):
Separate pre-freezing (e.g. in a deep freezer) and drying of less sensitive material outside the ice condenser chamber (see figure 2)
Typical drying vessels:
- dishes
- injection vials (stoppering under vacuum or inert gas)
- round-bottom-flasks, wide neck filter bottles
- ampoules

Special features of Martin Christ freeze dryers:
- Compact and powerful benchtop units with minimized space requirements.
- Modular concept for easy enlargement of the capacity with comprehensive range of accessories.
- Ice condenser chamber with inner condenser coil of high-quality steel allows for efficient vapour deposition.
- High-quality insulation of the ice condenser chamber reduces performance losses and avoids condensate formation.
- Ice condenser can be checked visually; easily accessible; rapid, easy defrosting and cleaning.
- Drying chamber is located directly above the ice condenser chamber with large cross-section provides high sublimation performance and reduced drying times.
- Pressure regulation for exact temperature control of the material analog to the vapour pressure curve for ice and water.
- Process-oriented control interfaces LDplus (Lyo-Display) and LSC (Lyo-Screen-Control) for exact and reproducible measurement and control of all process relevant parameters, like vacuum, shelf temperature.

Ice condenser capacities for every individual application:
When selecting the suitable freeze dryer the following points have to be considered besides the decision on the accessories and drying vessels:
- The required ice condenser temperature (-55°C for aqueous material, -85°C for products containing solvents or low-eutectic material).
- The maximum ice condenser performance (capacity per 24 hours resp. total capacity until defrosting).
