What are the two types of medicine droppers?

• A. Non-graduated and graduated
• B. Plastic and glass
• C. Disposable and reusable
• D. Graduated and non-graduated

Answer: (A)

Droppers are categorized by whether they have measurement markings. Graduated droppers have scale marks in units (like mL or drops per mL) so you can deliver a specific dose. Non-graduated droppers have no markings and are used when an approximate amount is acceptable, often relying on counting drops or estimating the volume. That pairing—non-graduated and graduated—captures the functional distinction most relevant to dosing, and the order doesn’t matter. Other options describe material (plastic vs glass) or usage (disposable vs reusable), which aren’t about the ability to measure a precise dose.
