Christ’s new, and highly advanced, LSC Plus freeze dryer controller uses a highly sophisticated digital processor and high resolution TFT display, complete with touch screen capability. The touch screen and improved “intuitive to use” menu system provides a new customer experience with its multiple features and functions.

When purchasing a Christ freeze dryer you will be pleased to know that they have integrated their highly regarded production optimised interface – the LSC plus control system into every freeze dryer.

New Modern Way of Freeze Drying

LSC plus freeze dryers offer you versatility for all freeze drying processes and also have the ability to provide you with data in graphical format.

LSC plus Summary of Features:

• Coloured touch screen with mimic diagram
• One screen – summary of set values
• Graphical summary of programs
• Program templates for different freeze drying applications
• Data storage on USB memory
• Detailed message information
• Different scale units °C/°F, mbar/hPa
• Password protection for improved security
• Integration into network structures

• PC based simulation available

Christ design and build their freeze dryers to comply with cGMP/GLP guidelines and the new controller software from Christ meets the current GAMP standard requirements.

Process Optimisation

The LSC plus freeze dryer controller is very user friendly and will provide you a choice of options to optimise your freeze drying processes. When using the new software you will be provided with key parameter analysis and documentation, as well as the automatic determination of critical product data.

Customers who use Christ freeze dryers also have the option of automatic tuning for set values based on process conditions. This means, their freeze dryers offer various options and support optimisation and process development.

Freezing Point

Christ’s clever LyoRx sensor monitors electrical resistance and the temperature of the product. The resulting data can be used with their LyoControl so you can identify the freezing/eutectic point of your product, a key factor in optimising any freeze drying process and provide a reliable estimation of critical temperature toleration so you avoid melting when freeze drying.

Product Temperature

Establishing the correct eutectic point of the product is crucially important, which is why every shelf is available with a PT-100 sensor. You can view the product temperatures on these shelves by using the LSCplus control system.

Pressure Increase test

Christ has numerous market leading solution, the Christ freeze dryers are available with an intelligent built in intermediate valve between the ice condenser and the product chamber. During the main drying phase the valve can open and close between drying and condenser chamber. If the valve is closed and a pressure increase is detected within the drying chamber this is an indication that the sample is not yet dry, once the pressure between the drying and the condenser chamber are equal this is an indicator that sublimation has stopped and thus the sample is dry.
