ZETA Freeze & Thaw Systems enable temperature-sensitive pharmaceutical products and solutions to bridge space and time. Controlled deep-freezing of the product solutions keeps them stable over long periods, so that they can safely be stored or transported before further processing.
ZETA Freeze & Thaw Systems are an economical and rational solution that offers a permanent improvement in the way we do scale-up and design of industrial freezing and thawing processes. The system approach covers the complete sequence from first laboratory experiments in the LabFreeze through controlled scale-up in the PilotFreeze and then to industrial production in the 10–300 L scale.
The storage of high-quality biopharmaceuticals is a major challenge for the industry. Proteins are easily affected by changes in ambient conditions and react sensitively to changes in their environment. The complex three-dimensional protein structure is held together by weak, intra-molecular interactions and is therefore particularly delicate.
The native folding of protein substances is essential for their efficacy: only if a protein is correctly folded will the right molecules be bound. Changes in the structure will have fatal consequences; in certain cases, they do not only result in a loss of efficacy, but may even cause pathological effects.
This means the process of storing an active protein substance must be the result of an exceptionally careful and sophisticated design process and all influencing factors must be known since the substance will often need to be stored for years.
