Tablet hardness testing (also called breaking force) measures the tablet mechanical integrity.
The tablet breaking force is depending on the tablet geometry. If the tablet shape is not round (e.g. oblong shapes), the user has to carefully place the tablets into the instrument - in a reproducible way!
Understanding this problem, SOTAX has been the first to develop a unique patented system called Auto Alignment™ which will align all your tablets for you with accuracy and reproducibility!
Some Tablet Hardness Testers available on the market use a constant loading rate (constant force) e.g. 20 N per sec, others use a constant platen movement (constant speed) e.g. 1 mm per sec. Data collected using these two modes of operation can not always be compared. The SOTAX range of Tablet Hardness Testers can all be ran in in either constant speed or constant force mode.
