Hormones & Steroids
Steroids, endogenous hormones such as the sex hormones estrogen and testosterone or the hormones of the adrenal cortex, cortisol and aldosterone, play a key role in metabolic processes and have a number of pharmaceutical applications, including hormone therapy, anti-rheumatic, anti-arthritic and bodybuilding preparations.
Mainly used in the global hormone replacement therapy, currently worth about $3.6 billion, the three major segments comprise estrogen, growth and thyroid hormone, and testosterone replacement therapy. A major market driver is the increased awareness of postmenopausal hazards amongst women; others include an ageing population, innovative drug delivery systems and the pharmerging economies.
Predominantly based on cholesterol, steroid hormones are synthesized in the endocrine glands and transported to target tissue by the blood. At their site of action, they dock with highly specific cellular receptors and perform a key function in protein formation. To produce steroid hormones for pharmaceutical applications outside the body, a direct extraction procedure from special nutrient solutions is used.
Counter-Current Liquid-Liquid Extraction
In continuous direct extraction from GEA, the fermented nutrient solution is treated by liquid-liquid extraction in a counter-current process. Following precipitation, concentration, crystallization and drying of the extract, the steroid hormones are available in the form of a raw salt and can be correspondingly processed by the pharmaceutical industry. In a continuous direct extraction process, the fermented nutrient solution undergoes a counter-current liquid-liquid extraction process (also known as also known as solvent extraction or partitioning). Following precipitation, concentration, crystallization and drying, the extracted steroid hormones are available in the form of a raw salt and can be subsequently processed by the pharmaceutical industry.
Fromfacility design and layout, manufacturing process controls (including adherence to standard operating procedures) and environmental control systems (HVAC) to extraction systems, industrial hygiene solutions and fully integrated, end-to-end containment solutions, GEA has the experience and know-how to implement and optimize end-to-end production lines for steroid- and hormone-based applications.

Décanteur centrifuge
Le décanteur est appelé à intervenir dès que la teneur en matières solides dans la suspension à traiter atteint un niveau particulièrement élevé. Ces machines offrent l'avantage d'un rendement de clarification élevé et d'une déshydratation optimale, et assurent en outre la séparation des liquides tout en éliminant les matières soli...
Lyophilizers (Pharma Freeze Dryers)
GEA's thorough understanding of the lyophilization process enables them to supply a comprehensive range of products and services, comprising laboratory equipment, pilot plants for research and small-scale production batches, industrial size pharmaceutical production freeze dryers.
Machine automation & control
Every plant or machine, which is designed for a reliable long-term operation, requires a control unit that enables the communication between the different system parts. It is one of the most important component that guarantees reliability and efficient operation.

La biotech à l’épreuve du réel
Le nouveau Centre d’application et de technologie (ATC) GEA de Sarstedt, au sud de Hanovre, n’est ni un showroom ni un ersatz de laboratoire. C’est un lieu conçu pour les essais, la collecte de données et les décisions précoces. Un endroit où l’on détermine si un concept biologique peut devenir un procédé industriel robuste. Cette étape est plus importante qu’il n’y paraît.
L'évolution des emballages alimentaires en 4 tendances
Si le thermoformage joue depuis longtemps un rôle central dans le domaine de l'emballage alimentaire, il doit aujourd'hui affronter un tournant majeur. À une époque comme la nôtre où les réglementations se durcissent, où les matériaux évoluent et où les coûts augmentent, il ne suffit plus que les lignes de conditionnement FFS ou <i>Form-Fill-Seal</i> (Former-Remplir-Sceller) fonctionnent de manière fiable : elles sont désormais déterminantes pour garantir la fraîcheur des denrées, un prix accessible et la recyclabilité. Examinez de plus près les grandes tendances qui dans le domaine du thermoformage façonnent le secteur de l'emballage et de la distribution alimentaires.
