Martin Christ Epsilon 1-4 LSCplus and Epsilon 2-4 LSCplus benchtop freeze dryers

The Martin Christ Epsilon 1-4 LSCplus and Epsilon 2-4 LSCplus benchtop freeze dryers are high-performance, universal laboratory and pilot systems for lyophilisation of solid or liquid products in ampoules, vials, glass flasks, plasma bottles or dishes. They share a geometrical likeness with large production machines and use similar temperature-controlling systems.

The Epsilon 1-4 LSCplus and Epsilon 2-4 LSCplus units have an internal ice condenser temperature with a minimum of -55 and -85°C respectively and are available with one shelf with 0.11 m² useable surface area. The dryers are suitable for pre-freezing products on temperature-controlled shelves; freeze drying (sublimation) of products according to pre-selected desired time, temperature and pressure profiles; and final drying of products.

The latest cooling techniques provide for shelf temperatures of -45 or -70°C (pre-freezing) in the compact chamber. This permits sensitive pharmaceutical and biotech products, eg, amorphous structures with a low glass transition point, to be freeze dried safely.

Simple, process-specific documentation is possible on all systems as a result of the LSCplus Lyo-Screen-Control and LyoLogplus interface. An added option is the Windows-based LPCplus software for PC-based process control and documentation. LPCplus is widely used in typical pilot freeze dryers up to large-scale productions systems and follows GAMP and cGMP guidelines.
