BTL have developed two advanced analytical instruments - the Lyostat freeze-drying microscope and the Lyotherm DTA and electrical resistance analyzer. Lyostat identifies eutectic / collapse temperatures, crystallization events, and the effects of annealing. Lyotherm investigates changes within the frozen product. This provides information such as glass transition and melting temperatures. It can also show endothermic and exothermic events occurring within the frozen sample, such as crystallizations and eutectic melting, which may have serious impacts on processing and stability of your product. Together these instruments provide vital information about the product which is necessary for successful formulation and process development.
