Christ Freeze Dryers Low Capacity

Laboratory Freeze Dryer Alpha 1-4 / 2-4 • Universal laboratory freeze dryer with 4 kg ice condenser capacity • Two alternative controlling systems for routine applications as well as for advanced drying processes • Modular design to increase the capacity several times due to the use of a wide range of accessories • Simple facilities for defrosting, cleaning, disinfection and sterilization • Construction of the freeze dryer according to GMP-/GLP-standards

User-friendly controller LD-2 (LyoDisplay) for routine applications: • • • Process Controller LSC-8 (Lyo-Screen-Control)

Easy handling with the new CHRIST-controller LSC-8 (Lyo -Screen-Control) • • • • •

Process Controller LSC-8 (Lyo-Screen-Control)

Two different drying principles enable the user to handle nearly every lyophilisation demand successfully: •

Process A (single chamber system): freezing and drying of sensitive or deep freezing substances on cooled shelves

•

Process B (double chamber system): drying of less sensitive products outside the ice condenser chamber on electrically heated shelves or in round-

Process A: Prefreezing and drying inside the ice condenser chamber

¼ VGA-LC-Display Graphical user interface with one knob operation (“turn and push”) Clearly arranged survey of process data in a freeze dryer-flow sheet Input of max. 32 freeze drying-pro grams in tabular form (option) WINDOWS-NT-based software available

The improved freeze dryers of the ALPHA-series establish the new standard in terms of a varied range of applications and advanced process control. In addition to an exemplary accessories range two “state of the art” controllers allow an individual unit configuration for routine applications as well as for high-quality drying processes.

Process B: Separate prefreezing and drying external to the ice condenser chamber
