For over 75 years, Copley has been supplying equipment to leading pharmaceutical companies all across
the world for testing tablets, capsules, powders, suppositories, semisolids and transdermals. Copley is
also the world’s leading manufacturer of inhaler testing equipment.
From simple hand-held units for use on the production floor, to semi-automated units for advanced analysis
in the laboratory, Copley offers tablet hardness testers to suit every analyst’s needs.
Together with friability, hardness (or breaking force) is a defining physical characteristic for a tablet.
High hardness values may indicate for example, longer disintegration and dissolution times, compromising
the speed of drug delivery.
On the other hand, if hardness is too low, then friability may be also high, giving rise to poor product
stability and compromised dose uniformity.
By examining correlations between hardness, disintegration, dissolution and friability, a dosage form with
optimum characteristics can be produced.
