Jan 24, 2022 · One last comment on the vial design: their caps, and more importantly, their septa, may differ. We commonly use PP caps with pre-assembled septa. These are convenient and minimise contamination from handling. The material the septa are made of is generally silicone or rubber, compatible with different solvents.
