Lyotherm Freeze Drying Impedometer

Frozen state solutions are a critical product stage or end product in a variety of industries, including freeze drying, pharmaceuticals, food storage and biotech. The Lyotherm3 combines electrical and thermal techniques. This unique dual analysis adds a new dimension to the data of this critical stage.

Impedance Analysis (Zsinφ) is a fixed frequency dielectric analysis providing an indication of the sample tracks molecular mobility, including events not picked up by thermal methods like DTA or DSC

Differential Thermal Analysis (DTA) measures the difference in temperature between a sample and a reference, highlighting exothermic and endothermic events e.g. crystallisation, eutectic melting and glass transitions

Combining DTA and Impedance analysis means Lyotherm is more sensitive to changes within the frozen structure than other exclusively thermal techniques.
