FAQ
- Why use 70% isopropyl alcohol instead of a higher concentration to wipe vial stoppers?
- The water in a 70% solution aids germ-killing efficacy; higher concentrations evaporate too quickly and are less effective. Most protocols specify 70% IPA or 70% ethanol for stopper disinfection.
- How long should alcohol dry on a vial stopper before inserting a needle?
- Allow the stopper to air dry for approximately ten seconds. Most antimicrobial action occurs during the drying phase; a still-wet surface can transport contaminants inward rather than removing them.
- What is the critical zone on a laboratory vial and why does it matter?
- The critical zone is the rubber septum—the area a needle passes through. It is the highest contamination-risk point because anything on its surface can be carried directly into the vial on needle entry.
