Measure Rupture Force

Measurement of rupture force of eggs, tablets and gel capsules using the TA.XTplus Texture AnalyserRUPTURE FORCE – the force that is required to produce a major break/rupture in a sample – can be related to the firmness and brittleness of a product. It is related to burst force – the force causing a sample to break suddenly and violently into pieces. Rupture force measurement can be crucial for such products as medical implants, which may be required to resemble soft tissue but must remain intact for the duration of their intended residence.

Bourne (1982) outlined a procedure to guide anyone through the necessary steps to select the correct test principle for each particular application. 

Here is our interpretation of the texture analysis method thought process, with a few quotes and guidelines from academics in the field.
