From routine drying to process optimization

The Epsilon 1-4 LSCplus freeze dryer is a very compact, general purpose high-performance laboratory and pilot unit for tabletop installation. The broad applications that could be covered with this unit extends from routine drying operations to process optimization tasks. The Epsilon 1-4 LSCplus is suitable for drying solid or liquid, mainly aqueous products in vials, ampoules, tubes, other glass containers or dishes.

Fast & flexible freeze-drying for best results

The single-chamber system has a 4 kg ice condenser integrated in the product chamber. The integrated drying manifold design facilitates the use of round-bottom flasks and wide-neck bottles. The directly cooled and heated shelves made from Teflon coated solid aluminium enable especially fast cooling and heating processes. The cooling and heating rates are nearly twice as fast as indirectly cooled shelves.
