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 pharmaceutical and medical products. Test procedures include: compression, puncture/penetration, tension, fracture/bending, extrusion, cutting/shearing.

Pharmaceutical and Medical Testing

 

 

 tablet-strength-test  bloom-jar-gel-test  tablet-coating-adhesion-fixture
Tablet Strength
This diametral crush test identifies
important differences in tablet
characteristics missed by
conventional tablet strength
testers, which only measure the
point force at which the tablet
breaks.
Tablet Coating 
Adhesion Fixture
This test provides a quantitative
measure of the adhesion strength
of the coating to the tablet surface.
Such a test is useful for studying
the consequences of changes in
tablet coating formulation variables.
Gels
Typical measurements include
gel strength, bloom strength
(according to ISO standard),
rupture force, adhesiveness,
gel forming points and
elasticity/brittleness.
 mucoadhesion-test-rig  bilayer-rig  syringe-test-rig1
Mucoadhesion Test Rig
Tests of solid dosage forms, semi-
solids such as ointments and gels
and even systems which solidify
on contact with the target organ
can be performed.
Bilayer Tablet Shear Rig*
The improved version of this rig
enables tablet layer separation
to be quantified.
NEW IMPROVED
Universal Syringe Rig*
Allows measurement of the
aspiration and extraction forces
of a wide range of syringe
types and sizes.
 granule-compaction-rig-pharm  capsule-loop-tensile-rig-pharm  cylinder-probe-capsule
Granule Compaction Rig
Can be used to assess granule
compressibility.
Capsule Loop Tensile Rig*
This rig measures the force
required to split one half of
a hard gel capsule.
Cylinder probes 
(small/large diameter)
Can be used to assess puncture/
compression force of e.g. capsules.
 powder-compaction-rig-pharm  tube-sachet-extrusion-rig  mini-three-point-bend-rig-pharm
Powder Compaction Rig*
Allows measurement of the
compaction forces of powders.
Tube/Sachet Extrusion Rig
Allows manufacturers to measure
the ease of removal and application
of products such as sauces, pastes,
creams and gels.
Mini 3 Point Bend Rig
Ideally suited to small diameter
samples such as tablets. Sample
supports can provide a 2mm
separation.
 film-support-rig  acoustic-emission-video-playback  alginate-raft-hook
Film Support Rig
This rig allows testing of thin, film-
like products to measure the burst
strength, resilience and relaxation
properties.
Acoustic Emission and 
Video Playback
Allow the collection of acoustic
data during a test and the
synchronisation of force data with
video frames - of particular interest
for the testing of brittle products.
Alginate Raft Hook
(British Pharmacopoeia)
Allows measurement of alginate
raft strength.
 tablet-disintegration-rig
Tablet Disintegration Rig
The Tablet Disintegration Rig facilitates reliable assessment of the mechanical properties of fast-melt tablets. It closely replicates the in vivo conditions of the human mouth, enabling manufacturers to examine water absorption and the disintegration of associated particles.
