Physical Testing Disintegration Testing: Measuring the time required for solid dosage forms to break down in a liquid medium. pH and Acidity/Alkalinity: Determining the hydrogen ion concentration of liquid formulations, solutions, or suspensions. Loss on Drying (LOD) & Water Content (Karl Fischer Titration): Quantifying moisture and volatile matter in powders and granules. Viscosity: Measure the viscosity of the samples using capillary and rotational viscometers Particle Size Distribution: Measuring particle dimensions (laser diffraction or microscopy) which affect bioavailability and formulation stability. Dissolution Testing: Evaluating the rate and extent of drug release from tablets and capsules over time
