Why the water is already in the pen
Lyophilization, the bypass channel and the transfer step a dual-chamber cartridge does for you, inside sealed glass.

Storage
Storing a dual-chamber pen before and after the twist
Unmixed: dry, out of direct light, never frozen. Mixed: 2 to 8 °C. The reasoning behind both rules, and how to apply them in a real lab.

Lab testing
Identity, purity, endotoxin: what each test answers
Mass spectrometry, HPLC and the LAL assay each answer one question about a lot. What each can say, and what it cannot.
