Highest manufacturing standards, outstanding material quality and extremely precise process control guarantee the most efficient handling of valuable pharmaceutical products. For product preparation, the vessel is first filled with Water for Injection (WFI). Previously weighted raw materials (e. g. concentrates, powders) are then added and dissolved in the water by a circulation pump. For accurate level control, differential pressure meters and load cells are used. To achieve optimum and repeatable product formation, temperature and pressure inside the vessel are controlled within narrow limits. At the outlet of the vessel, the finished product runs through a sterile filter. For Centec preparation vessels a large range of optional equipment is available such as agitators, homogenizers, valves, measurement instruments, and sampling devices. The design of the vessels provides excellent cleaning and sterilization characteristics.
