Also known as take-off force, the detachment force is the force needed to detach the tablet from the base of the die or the lower punch tip. Detachment stress is calculated from detachment force to account for the punch and die geometries (Stress = Force/Area). Like ejection stress, it is related to lubrication with high detachment stress values indicating that the formulation is poorly lubricated and at risk of tablet defects.
The D-series compaction analysers feature a unique, integrated detachment force measurement system. When combined with the Gamlen Dashboard software, detachment force profiles are generated automatically which identifies tablets at high risk of sticking/picking. When using The R500 compaction analyser detachment force can be measured using a seperate hand-held force meter (supplied separately).
