Opt for alternatives like "kept separate" or "isolated from" to express the idea of distinct containment more effectively.

Avoid using "contained apart" when you simply mean something is separate. Clearer phrases such as "kept separate" or "isolated" are preferred. "Contained apart" implies a more specific scenario where something is both enclosed and distinctly separate from other contents.
