Overview

Universal laboratory freeze dryer for routine applications; low ice condenser temperature allow drying of samples containing organic solvents (eg, alcohols); with new user friendly unit control "LYO Display LDplus".

LDplus (Lyo Display Plus) stands for a comfortable, easy-to-use and self-explaining user interface for controlling routine freeze drying processes, combining functionality and convenient operation.

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.
Features

• 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 optimisation/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
• RS-232 communications interface (PC) available as an option, eg, for process documentation software LyoLog LL-1
