Significance of shelf life studies on pharmaceutical products

Any medicinal product does not remain stable for all time. The potency or strength of the active ingredient drops over a period of time. Visually also formulations change and become discoloured, develop spots, becomes powdery or show other distinct changes so the concern arises as to how long after manufacture the formulation can be used […]

Safe storage practices for chemicals in laboratory refrigerators

Laboratory chemicals are stable only within prescribed temperature limits. High purity chemicals used as reference standards require preservation in low temperatures so that the concentration of active constituent does not change over their prescribed usage life. Flammable liquids also require to be stored under low temperatures so as to prevent formation of explosive vapours over […]

Disposal of Laboratory Samples

Laboratory samples and waste disposal is a specialized practice and requires adherence to prescribed techniques otherwise such waste can lead to environmental hazards.

Understanding differences between solutions, emulsions, colloids and dispersions

Analysis of samples in laboratories more than often requires pre-treatment steps for extraction, isolation, concentration or dilution to measurable concentration ranges. This is generally achieved by dissolving the sample in a suitable solvent. However, the solubility of a compound in a solvent depends on the affinity between the compound and the solvent. Depending on the […]
