What utensils must a pharmacy keep for operations?

The requirement for a pharmacy to maintain devices that can measure from 0.1ml to 500ml aligns with the need for accurate and precise measurement in pharmaceutical preparations. Since pharmacies often engage in the compounding of medications, including both liquids and solids, having a range of measuring utensils ensures that pharmacists can efficiently and safely prepare prescriptions according to established formulas or physicians’ orders.

A device capable of measuring such a broad range allows pharmacists to work with various types of formulations, whether they need to dispense a small volume of an oral solution or a larger volume for parenteral use. Precision in measurement is critical in pharmacy practice to ensure therapeutic effectiveness, maintain safety, and comply with legal requirements for pharmaceutical compounding and dispensing.

While the other options mention specific measurement tools—measuring cups, mortar and pestle, or a measuring device with a sensitivity of just 1g—they do not encompass the necessary variety and precision for a pharmacy's operational needs. The range from 0.1ml to 500ml is essential for effective pharmacy practice.
