Maximize sustainability and freeze-drying efficiency with EcoStream™.

Lyovapor™ L-250 featuring groundbreaking EcoStream™ technology: the most eco-friendly freeze-drying solution for your laboratory. BUCHI innovative cooling technology significantly lowers the environmental impact of the instrument without compromising our commitment to quality and reliability.

EcoStream™ Innovation

• Innovative compressor design enables the condenser to reach temperatures as low as -85 °C.
• Features a low Global Warming Potential (GWP) rating of just 4 with natural coolants, reducing the environmental impact.
• Lower the amount of heat output and noise emissions in your lab.

Save energy, enhance performance

• Profit from reduced electrical energy consumption due to the smart design of BUCHI compressor.
• Achieve an ice condenser capacity of 4 kg /24 h, with a total capacity of 5 kg.
• The stable ice condenser temperature allows for the efficient collection of water and organic-based solvents.

Embrace efficiency and elevate control

• Featuring Infinite-Control™ technology that offers unprecedented levels of process control via display, software, and mobile app.
• Benefit from sample protective state and endpoint determination for a safe and short freeze drying run.
• Easy installation on a bench, trolley, or fume hood.

Modularity

• 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.

Basic instrument

• 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.

Pro instrument

• 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.

Process analytics

• Endpoint determination using pressure and temperature difference tests for heated shelf applications and processes on a manifold steel drying rack.

Sample protection mode

• 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.

Process monitoring

• 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.

Enhance your process with Lyovapor™ 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.
