Any of the texture analyser range can be used for the product tests listed below.

A selection of special attachments and typical measurements which are commonly used in this application area are shown above. However, this does not show the complete range of attachments available for the testing of medical device products. Test procedures include: compression, puncture/penetration, tension, fracture/bending, extrusion, cutting/shearing.

 metered-dose-inhaler-test  needle-sharpness-test  tensile-grips-seal-strength
Metered Dose Inhaler
The metering valve, whose
performance is assessed with this
test, is a critical component of a
finished metered-dose inhaler.
Needle Sharpness
Determined by standard substrate
penetration, this is an important
characteristic for patient comfort.
Tensile Grips
Used for the assessment of
Seal Strength (an important
characteristic of packaging to
ensure sterile integrity).
 cylinder-probe-contact-lens  syringe-test-rig1  abrasion-test-rig
Compression Probes
Allow the hardness assessment
of e.g. contact lenses.
NEW IMPROVED
Universal Syringe Rig*
Allows measurement of the
aspiration and extraction forces
of a wide range of syringe
types and sizes.
Abrasion Test Rig
Analyses the frictional properties
of e.g. dental abrasive strips.
