Author(s) : RINDLER V., SCHWINDKE P., HESCHEL I., RAU G.
Type of article: Article, IJR article
Summary
A new freeze-drying device was built to allow lyophilisation at very low temperatures. The paper gives a short description of both the construction and performance data. The device is based on a simple single-chamber principle. The condenser, as well as the sample tray, consists of copper pipes cooled respectively by liquid nitrogen and the external ethanol flow of a cryostat. The data acquisition and the dynamic control of the freeze-drying device is computer-assisted with specially designed software modules.
