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

John Morris Scientific has announced the release of two Martin Christ benchtop freeze dryers: Epsilon 1-4 LSCplus and Epsilon 2-4 LSCplus. These are high-performance, universal laboratory and pilot systems for lyophilisation of solid or liquid products in ampoules, vials, glass flasks, plasma bottles or dishes.

The two models share a geometrical likeness with large production machines and use similar temperature-controlling systems. They are capable of operations including: prefreezing products on temperature-controlled shelves; freeze drying (sublimation) of products according to preselected desired time, temperature and pressure profiles; and final drying of products.

The 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.

New cooling techniques provide for shelf temperatures of -45 or -70°C (prefreezing) in the compact chamber. This permits safe freeze drying of extremely sensitive pharmaceutical and biotech products, such as amorphous structures with a low glass transition point.
