Pharmaceutical metal detectors can be installed at identified points across the production line.

At the beginning of the line, metal detectors inspect APIs and excipients as powders or granules before tableting or encapsulation through gravity-fed systems to detect metal contaminants before processing begins. By positioning inspection before compression, contaminated material can be removed early in the process, reducing the likelihood of a full batch being affected.

The Tablex-PRO pharmaceutical metal detection system from METTLER TOLEDO is designed specifically for solid-dose applications. It integrates directly with tablet presses and de-dusters to inspect products immediately after formation. If a metal contaminant is detected, a minimal number of tablets or capsules are diverted into the reject container by the fast-acting reject device. This approach helps minimize product loss while maintaining tight process control. A lift flap diverter reject mechanism offers straight-line product flow for delicate products. The side diverter reject mechanism is ideal when inspection height space is restricted.
