Which of the following is NOT a required equipment for a nuclear pharmacy?

In the context of a nuclear pharmacy, the required equipment is focused on ensuring the safe handling and preparation of radioactive materials. Each piece of equipment serves specific functions necessary for the effective operation of such a facility.

A laminar flow hood is essential for maintaining a sterile environment when compounding sterile preparations, which is crucial in handling radiopharmaceuticals. A dose calibrator is also a vital piece of equipment used to measure the quantity of radioactivity in a given sample, ensuring accurate dosing for patient administration. A pH apparatus is important for assessing the acidity or alkalinity of solutions, which can affect the stability and effectiveness of certain compounds.

In contrast, chromatography apparatus, while useful in some laboratory settings for analyzing substances, is not specifically required for the operation of a nuclear pharmacy. The primary functions of a nuclear pharmacy do not necessitate chromatography, making it the least essential of the listed equipment. Thus, it is accurately identified as not being a required piece of equipment for a nuclear pharmacy.
