The Lyovapor™ L-200 is a quality freeze drying solution with stable process parameters and end-point determination. Moreover, various drying chamber options ensure high flexibility and with infinite-Control™, the system offers easy method creation, method running, data logging and chart recording in real time. The freeze dryer comes with a 6 kg/-55°C condenser, control unit, vacuum pump and vacuum regulation. More info

BÜCHI Labortechnik AG
Ice condenser capacity: infinite
Maximum performance: ≥ 12 kg / 24h
Lowest condenser temp.: -105 °C
Shelf heating range: Up to 60 °C

With two alternately working condensers, the Lyovapor™ L-300 is the first freeze dryer to allow for continuous sublimation and thus, unlimited ice capacity. The system offers lyophilization of water and organic based solvents at -105°C. Moreover, adjustable drying volume and various drying chambers such as manifolds, heated shelves or a combination of both ensure maximum sample flexibility. Stable parameters, Infinite-Control™ and an automatic, hygienic cleaning of the ice condenser ensure both convenience and economical benefits. More info

Ice condenser capacity: 4 to 24 kg
Maximum performance: 4-18 kg / 24 h
Temperature range: -55 to -85 °C
Product temperature: -25 to -50 °C

Larger laboratory freeze dryers that are particularly suited for advanced applications requiring more process control and/or temperature-controlled shelves for the product. Single or double chamber instruments with vacuum control are available. More info

Martin Christ
Ice condenser capacity: 4 to 10 kg
Maximum performance: 3-8 kg / 24 h
Temperature range: -55 to -88 °C
Product/shelf temperature: -45 to -75 °C

Pilot freeze dryers for process optimization or small batch production. They are used for drying solid or liquid products including the drying of bacteria or cultures, viruses, blood plasma, serum fractions, antibodies, vaccines, medicines such as vitamins, biomass and plant extracts for biochemical tests.

Combination possibilities with freeze-drying systems.

Rotational vacuum concentrators are used for evaporation, drying, purification and concentration of samples. The sample solvent evaporates at room temperature, at low pressure and without having to be frozen. There is no thermal strain on the sample which is important when working with thermally sensitive biological or clinical substances. Rotation vacuum concentrators provide a method between distillation and freeze drying. More info
