Pharmaceutical products may be as thin as water or they may be a little more viscous, like cough syrup. Regardless of the type of filling machine used for a pharma product, the main requirement is that the machine be sanitary. Sanitary filling equipment is used to protect against contamination during the packaging process while keeping the process efficient and clean. When bottles are used for a pharmaceutical product, rinsing machines are very likely to be incorporated in to the packaging solution. Again, such a machine helps to protect against contamination. Capping machines may run from spindle and chuck for screw-on type closures to corking equipment or snap type machines for tubes, vials and similar containers. Labeling machinery for pharma products can be applied in a variety of manner, but the labels being applied may be smaller than those seen in other industries, as small containers such as those mentioned above are more prevalent. Complete filling solutions for pharmaceutical products are available in tabletop, semi-automatic and automatic designs and may even incorporate a Monoblock Filling System for smaller containers.
