Ice condenser temperature –55°C.
Experience, expertise, adaptability and flexibility for all freeze-drying procedures Based on over 55 years experience, Martin Christ offers a comprehensive range of products for both routine and specialized freeze-drying procedures. The diverse and laboratory-tested accessory line allows the basic unit to easily handle a variety of routine and advanced processes.
Guaranteed consistent results for routine freeze drying Routine processes place continual demands on the operating system. A high degree of consistent, user-friendly, intuitive technical functions and operational flexibility are expected
features. The basic equipment of the Alpha and Beta series, combined with their specially developed operator interface "LDplus" (Lyo-Display), live up to the challenges of safe and successful freeze drying day after day.
Innovative technology gives results
- Compact, high-performance laboratory equipment requires little space
- The building-block principle allows procedural and capacity expansion with a far-reaching variety of accessories
- Ice condenser chambers with high-quality stainless steel inner condenser coils
- Easily accessible ice condenser, simple facilities for defrosting, cleaning and decontamination (GMP/GLP requirements), drain valve included
- Visual control of condenser icing during drying
- Low performance losses and no condensation of water due to high-quality thermal insulation of the ice condenser chamber
- Drying chamber located directly above the ice condenser provides high sublimation performance and reduced drying time
- Sample freezing in the ice condenser chamber from -25°C (single-stage compressors) to -50°C (double-stage compressors) and gentle freeze drying
- Digitally displayed ice condenser temperature and indirect determining of the product temperature corresponding to the vapour pressure curve above ice, vacuum control for optimization of process times (option)
- Data interface RS 232 optional, e.g. for process documentation software LyoLog LL-1
- Graphic LC display with a clear layout showing the most important process data (ice condenser temperature, process time, section time and vacuum)
- Comfortable and self-explaining menu guidance in German, English or French language
- Vacuum control for optimization/reduction of process times (electromagnetic pressure control valve available as accessory)
- Conversion of product temperature and vacuum according to the vapour pressure curve above ice
- Suitable for drying in12 or 24 round bottom flasks, wide neck filter bottles, ampoules and on 3 or 5 unheated shelves Ø 265 mm or 5 unheated shelves Ø 360 mm, alternatively sealing device with 2 or 4 unheated shelves Ø 250 mm).
