The freezing stage governs several critical parameters of the freeze drying process and the quality of the resulting lyophilized products. This paper presents an integrated ultrasonic transducer (UT) in a stainless steel bottle and its application to real-time diagnostics of the water freezing process. The sensor was directly deposited onto the stainless steel bottle using a sol-gel spray techn...

In the present study the solubility of beta-cyclodextrin and 2-hydroxypropyl-beta-cyclodextrin at sub-zero and elevated temperatures (-10 and +30 degrees C) for a given composition of methanol/water and acetonitrile/water binary mixtures (Xs = 0.16) was studied. Moreover, the freezing temperature profiles of acetonitrile-based chromatographic mobile phases were measured, and the obtained result...
