Pharmaceutical physical testing systems are essential quality control instruments used to evaluate the mechanical strength, structural integrity, and dissolution behaviour of solid dosage forms. These tests ensure that tablets and capsules meet pharmacopeial requirements (USP, Ph. Eur., IP) for safety, efficacy, and consistent drug release performance. The four core analytical methods—dissolution, disintegration, friability, and hardness testing—form the foundation of routine solid dosage form quality assurance in pharmaceutical manufacturing and laboratory environments.
