Identify the actual product
Review the manufacturer, label, intended use, ingredients and regulatory status. A laboratory solution and a prescription drug product are different, even when names sound similar.
A preservative is not sterilization
Adding a preservative-containing solution does not establish that another material is sterile. Scale does not test sterility, and its research products are not for human or clinical use.
Review it separately
Do not assume an accompanying diluent has the same sales or advertising rules as research stock. Ask qualified counsel about the specific product and channel. This definition is not medical or administration guidance.
