The equipment, and what each piece is
If you have read this far you know what the words mean and what the site will not tell you. This last step covers the physical objects, because knowing what a thing is called is the difference between buying the right one and guessing.
The items, and what each one is
- Bacteriostatic water — sterile water containing a small amount of benzyl alcohol as a preservative. The preservative is what allows a vial to be entered more than once. Sterile water without it is a different product and is single-use.
- Syringes — sold by the volume they hold and marked in different scales. A U-100 insulin syringe is marked in units, where 100 units is one millilitre. That is a volume scale, not a measure of how much compound is present.
- Alcohol prep pads — single-use isopropyl wipes for the vial stopper and the skin.
- A sharps container — a rigid, puncture-proof bin for used needles. Most areas have rules about how these are disposed of, and a household bin is not one of them.
- Storage — these compounds are usually kept cold, and an insulated case is what keeps them cold in transit.
None of this tells you how much of anything to use, or in what order. That is step five, and the answer is still a pharmacist.
