Questions buyers ask

How many 30 mL vials are in a box?
25 vials. We sell by the box only, so 100 vials = four boxes; you can mix sizes in one quote.
Can every vial in my order come from one lot?
Ask for it in the quote. We check the lot sizes in stock and confirm in writing which lot (or lots) you receive, with each lot's COA.
Is the 30 mL vial worth it over 10 mL?
Only if the opened vial is used up within 28 days. For low use, 10 mL wastes less, even if the 30 mL box costs less per mL.
