Several drying chambers accommodate a wide range of applications. Unheated and heated shelves in combination with manifold, plain and stoppering cover as well as manifold rack with 12 to 24 connections.
Easily dry both liquid and solid materials in flasks and trays. The stable ice condenser temperature ensures complete solvent collection, even for large sample quantities, complemented by precise endpoint determination.
Offers advanced drying capabilities in vials and trays. Achieve precise control of residual moisture and faster drying times. This instrument allows customized method programming, ensuring enhanced sample integrity and the highest level of reproducibility. Additionally, it features a robust heating shelf.
Endpoint determination using pressure and temperature difference tests for heated shelf applications and processes on a manifold steel drying rack.
The pro version features a sample protective state that automatically activates if the sample temperature rises above the set collapse temperature, offering peace of mind by safeguarding precious samples.
The system provides a real-time graphical display of key process parameters, including drying chamber pressure, sample temperature, and shelf temperature. These can be monitored directly through the interface as well as via an app and accompanying software.
Experience comprehensive data management tools, allowing for detailed analysis and evaluation of recorded data as well as customized reports. Designed for user-friendly operation, it allows you to conveniently create and start methods right from your desk.
