Christ Epsilon 1-4 -55°C LSCplus & 2-4 -85°C LSCplus Pilot Freeze dryers – up to 4kg

Product Details

The Epsilon 1-4 /2-4 LSCplus freeze driers are very compact, general purpose high-performance laboratory and pilot units for bench-top installation. The application area of these units extends from routine drying operations to process optimization tasks.
This unit is suitable for drying solid or liquid, mainly aqueous products in vials, ampoules, tubes, other glass containers or dishes.
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.
