Abstract

The TA.XTPlus Texture Analyzer from Stable Micro Systems can very precisely quantify swelling and disintegration behaviors of almost any type of product. Swelling applications include tablets, gels, films, pellets, mucosal tissues, super-absorbent polymers, sponges, aquaculture feed, chemical and yeast leavened products, etc. Disintegration behaviors are common for fast- disintegration tablets, powder cakes, detergents, aquaculture feeds, etc. Swelling and disintegration are measured with highly similar test settings. Materials that swell when exposed to moisture or otherwise activated can be characterized with the TA.XTPlus Texture Analyzer. Different methods of mounting samples may be required, depending the sample characteristics or geometry. The swelling can be determined by either distance or force measurements.
