Texture Analysis in Action: the Abrasion Test Rig

Syringe RIg test using the TA.XTplus Texture Analyser The ABRASION TEST RIG (HDP/ATR) analyses the frictional properties of a wide range of materials such as sandpaper, dental abrasive strips and flexible nail files.

This enables manufacturers to highlight strengths, weaknesses and variations in product lines and materials.

Prior to performing the test, a sample of the abrasive material is held in place in a self-tightening grip.

Texture Analysis in Action: Friction Testing

Horizontal Friction System fitted to the TA.XTplus Texture AnalyserStable Micro Systems offers two options for Friction Testing attachments.

The HORIZONTAL FRICTION SYSTEM (A/HFS) comprises a support leg and levelling feet which are fixed to the Texture Analyser, so that the assembly can be laid in a horizontal position. 

A platform is fitted to the base on which a friction sled, which is attached to the loadcell, is constrained to slide over the sample.

Additional load may be provided by adding weights positioned centrally on the sled. This arrangement offers the advantage of measuring sliding friction in both directions and also during cycling. Typical applications include films, creams and packaging.

Testing the Mechanical Strength of Coronary Stents

Coronary stent
Vascular stents are commonly used as a minimally invasive way to treat stenosis in arteries and improve blood flow to the heart, kidneys, brain and legs. 

Due to the challenging service environment that stents face in vivo, the radial stiffness of a stent is critical to its function of keeping the arteries open and eliminating abrupt closure. Measurements and reporting methods of a stent’s radial stiffness both assist industry in the development of new stent designs and allow regulatory authorities to better evaluate these designs.
