A wet column generator is equipped with all the following parts EXCEPT:

A wet column generator primarily consists of an alumina column, a lead shield, and a collection port. The alumina column is essential as it acts as the stationary phase in the chromatographic process, which is crucial for separating and purifying the desired radioisotopes. The lead shield is utilized for radiation protection, ensuring that both the operator and the environment are safeguarded from any harmful emissions during the process of radiopharmaceutical production. The collection port allows for the elution of the desired isotopes once they are separated and purified.

However, the charging port is not a standard part of a wet column generator. This term may imply a feature related to loading materials or reagents, which is not a function typically associated with wet column generators. In nuclear medicine, generating radioisotopes often involves the elution process from the column rather than additional charging or loading mechanisms. Therefore, the absence of a charging port makes it clear that it is not part of the essential equipment of a wet column generator.
