Freeze drying of high solvent concentration

Product catalog summary

Overview
The document provides information on the Epsilon Solvent series of freeze dryers by Martin Christ, designed for safe and sustainable freeze-drying with solvents. It highlights the Epsilon 2-6D and Epsilon 2-10D models, which are tailored for high solvent concentrations.

Product Specifications

Laboratory Freeze Dryer: Includes standard accessories and models like Alpha 3-4 LSCbasic.
Pilot Freeze Dryer: Offers standard, special configurations, and extension options for solvents.
Epsilon 2-6D Solvent: Capable of handling -88°C, 6 kg, approximately 840 x 2 ml or 42 x 100 ml.
Epsilon 2-10D Solvent: Capable of handling 10 kg, approximately 3,065 x 2 ml or 98 x 100 ml.

Key Features

Solvent-resistant versions for high concentrations (e.g., 100% Acetonitrile, 100% Dioxane, 60% tert. Butanol).
Compact stand-alone units with defined PAT tools for process control (e.g., MTM, LyoApp, WTMplus 2.0).
High-quality materials with no ignition sources, capacitive vacuum sensors, and scroll pump.
Automatic inertisation to remove oxygen and use of natural refrigerants.

Safety and Reliability
The Epsilon Solvent series ensures safe freeze-drying processes with high solvent concentrations. The units feature a solvent-resistant stainless steel door with a glass window and an oil-free scroll pump with ATEX explosion protection certification.

Classification and Recommendations
The document suggests a classification scheme (low, medium, high) for solvents used in freeze-drying, aiding in selecting the appropriate freeze dryer configuration based on solvent concentration.

Freeze drying of high solvent concentration-2

Freeze-drying with solventsSafely and sustainably Solvents in freeze-drying processes Freeze-drying of solvents is being used more and more. This gives end products containing solvents a longer shelf life without adversely affecting the required properties. In physical terms, freeze-drying of solvents is not a problem. However, both liquid and volatile solvents can have a persistent adverse impact on freeze dryer components. This can lead to device outages or, in the worst case, pose a threat to user safety. Care is therefore required in choosing parts that come in contact with liquids and vapours....
