Should there be any punctuation marks in this sentence?

Question

other than full stop.

The sentence is "Sample B must be isolated." Is it missing a comma or a hyphen between the words Sample and B?

Answer 1

I can see no reason to punctuate any further.

Chef Ramsay is in the kitchen.

Captain Kirk is on the bridge.

HMS Victory must be repaired urgently.

Sample B must be isolated.

They're all the same.

Afterthought

If 'Sample-B' is the name of the sample rather than just 'B', then maybe yes.

Example

"We placed Sample-B in Room-B."

"Why?"

"Because Sample-B must be isolated."

In this case we have to distinguish between Sample-B and Room-B so we can't just say 'B'.
