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

A selection of special attachments and typical measurements are also shown which are commonly used in this application area. 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.


Typical measurements include:

  • Needle Sharpness

  • Extrusion force: syringes
  • Metering valve performance: inhalers
  • Material Strength (tensile or compressive): catheters, tubing, surgical gloves, contact lenses
  • Tensile Strength: bandages, medical gloves, sutures, stents, adhesives
  • Compression fatigue: breast implants
  • Bond Strength: between thread and suture needle
  • Puncture Resistance: breast implants
  • Syringeability (expulsion and extraction forces)

Metered Dose Inhaler

Hypodermic Needle Sharpness Testing

Tensile Grips

Metered Dose Inhaler
The metering valve, whose 
performance is assessed with this 
test, is a critical component of a 
finished metered-dose inhaler. 
Patients need to rely on their 
inhaler to provide them with the 
required medication which is often 
at a crucial time when physical 
strength may be very low.

Syringe & Hypodermic Needle
Needle sharpness is an important 
characteristic for patient comfort. 
This is determined by a puncture 
test where the needle is pushed 
through a substrate which is 
rigidly held. The syringe body dispenses its contents by forward
extrusion and is tested by
measuring the average and peak 
extrusion force.

Tensile Grips
Used for the assessment of 
Seal Strength (an important 
characteristic of packaging to 
ensure sterile integrity).

Contact Lense Compression

Compression Probes
Allow the hardness assessment of
e.g. contact lenses


Application Studies are available for the testing of MEDICAL DEVICE products using the TA.XT2i, TA.XTplus, TA.XTExpress  or TA.HDplus texture analysers.

In addition, scientific papers have been published which reference the use of the TA.XT2i/TA.XTplus/TA.HDplus in the testing of MEDICAL DEVICE products.
