FIRST VIAL

Getting started, step by step.

Five steps from an empty vial to safe, sterile research practice — beginning with everything you need on hand.

  1. 01Your Supplies ChecklistEverything you need before your first vial

    Why this matters:Contamination is the #1 cause of injection-site reactions. Using sterile, single-use supplies isn't optional — it's the baseline for safe research practice.
