Inter-laboratory proficiency results of blood alcohol

Feb 01, 2020· Moreover, ethanol degradation might increase in tubes with larger head-space volumes, therefore blood volumes in vials should be maximized. In preliminary tests, some glass vials (total volume 5 mL) cracked during freezing and thawing when filled with 5 mL of water. None of the tubes were damaged when filled with 4 mL of water.
