Pharmacy is the healthcare industry that connects the health sciences and the chemical sciences, with the responsibility of ensuring the safe and effective use of medicines. Pharmaceutical experiments mainly study the source, processing, properties, function, analysis, identification, deployment, production, storage and search for new drugs of drugs. For pharmaceutical experiments, conventional drug forms are granular, powder and liquid. Among them, in the process of pharmaceutical experiments, the drugs need to go through several experiments for quantitative proportioning to form the final required medicines, which requires the personnel involved in the experimental proportioning to repeatedly measure and sample the medicines for experimental work.
