The Lyostat freeze-drying microscope is an analytical system that enables observation of a sample structure during the drying and heating stages encountered in a lyophilisation process and allows the determination of the critical parameters of the sample. 

Lyotherm is a collection of differential thermal analysis (DTA) and precision instruments and measuring electrical impedance (Zsin) for one. It is used to detect freeze-dried formula products eutectic point temperature (Teu) and melting temperature (Tm). value of the detection Zsin will provide an important basis and information order understand the product melting
