What is the dead-space loss per draw with a 27G needle at 20 mg/mL?

Asked 27 Apr 2024Modified 2.3 years agoViewed 7.3k times

Concretely: a 27G needle · 20 mg/mL.

I want the working, not the result — I need to be able to redo it with different numbers.

I care about the precision as well as the value — I want to know how many figures are real.

How many significant figures are actually justified here?
