Answer :
Final answer:
For safety and practicality, containers used in a science or laboratory setting should ideally be free of leaks, not smelly, and have secure handles.
Explanation:
From the question, it seems like it's about the characteristics of containers such as those made of high-density polyethylene, steel, or glass, which are often used in a science setting. If that's the case, it would be best for these containers to be free of leaks, not smelly, and to have secure handles.
It is not ideal for a container to have leaks because the substance inside could spill out and cause harm or a mess. It should also not be smelly as that could indicate the presence of a toxic or harmful substance. Secure handles are important for safety reasons, ensuring that you can handle the container without dropping it or spilling its contents.
