@Randy I did order a few more single H BAC, but my usage is so tiny that I may not run out of them until their expiry next year.
Some researchers claim they use asceptic techniques and just use the same vial until it's fully empty, regardless of the 28 day rule or expiration.
What's the community sentiment? It feels okay to me given that most of the researchers are using it in a setup that's not poking vials aggressively like a clinical facility.
