BUCHI Labortechnik is continuing to expand its freeze-drying portfolio by introducing the Lyovapor™ L-250. The L-250 builds on the robust framework of the existing L-200 model, offering an extended temperature range. But what truly sets the L-250 apart is its commitment to sustainability and the introduction of EcoStream™  technology.


The new Lyovapor™ L-250 is a leap forward in sustainable laboratory practices. The introduction of EcoStream™ technology has reduced the environmental footprint of the instrument without compromising on efficiency and reliability. The ground-breaking compressor design uses natural coolants and achieves an ice condenser temperature of -85 ºC. The coolant gas used has a low global warming potential (GWP) of just 4, helping to make the instrument the most environmentally sustainable solution available to date. Heat output and noise emissions have also been reduced, contributing to a better working environment. The innovative design ensures that high efficiency doesn’t compromise performance, making it the perfect choice for laboratories looking to reduce their environmental footprint without sacrificing quality.

The Lyovapor™ L-250 comes in basic or pro configurations with touchscreen controls and a wide range of drying chambers for basic and advanced processes. The instrument features a total capacity of 5kg and a condensing capacity of 4 kg/24 h for aqueous or organic mixtures. This allows for a high degree of flexibility and contributes to a fast, efficient, and sample-quality focused freeze-drying process.

Like all instruments in the Lyovapor™ line, the L-250 guarantees a stable condenser temperature that allows for complete solvent collection, even for large sample batches. For delicate samples, the instrument features a sample protective state that ensures such products are treated with care by activating if the sample temperature rises above the set collapse temperature. Endpoint determination guarantees efficiency for the customer, and the compact design ensures that the unit can easily be installed on a bench, trolley, or fume hood.

In addition to the intelligent and innovative cooling technology, the L-250 features Infinite-Control™ technology that makes operation a breeze. Process parameters are available via live graphics on the instrument’s display. Thanks to the Lyovapor™ software, creating and running methods couldn’t be easier, as well as logging data and recording charts in real-time. The mobile app allows monitoring of the process run from any location and provides push notifications updating you on the freeze-drying progress.

Whether you’re a small research facility or a large-scale industrial laboratory, the Lyovapor™ L-250 is tailored to meet your needs while pushing the boundaries of sustainable innovation.
