BUCHI Labortechnik Lyovapor L-250 green freeze dryer

BUCHI’s Lyovapor L-250 freeze dryer has been designed to enable sustainable laboratory practices, introducing EcoStream technology to reduce the environmental footprint of the instrument without compromising on efficiency and reliability.

The compressor design uses natural coolants and achieves an ice condenser temperature of -85°C. The coolant gas used has a low global warming potential (GWP) of just 4, helping to make the instrument environmentally sustainable. Heat output and noise emissions have also been reduced, contributing to a comfortable working environment.

The product comes in basic or pro configurations with touchscreen controls and a wide range of drying chambers for basic and advanced processes. It features a total capacity of 5 kg 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 freeze-drying process that is focused on sample quality.

Like all instruments in the Lyovapor line, the L-250 provides 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 means such products are treated with care by activating if the sample temperature rises above the set collapse temperature.

In addition to the intelligent and innovative cooling technology, the product features Infinite-Control technology that makes it easy to operate. It can be tailored to the needs of working environments from small research facilities to large-scale industrial laboratories, enabling sustainable innovation.
