Reconstitution Steps

  1. Draw 2.0 mL bacteriostatic water using a sterile syringe for the main concentration reference shown below.
  2. Slowly add the BAC water down the side of the vial wall.
  3. Gently roll or swirl the vial until the material is completely dissolved. The solution should appear clear. Do not shake!
  4. For higher-concentration preparations, verify that the material is fully dissolved before recording the final preparation details.
  5. Label with compound name, vial amount, concentration, solvent volume, preparation date, storage conditions, and handling notes.
  6. Store refrigerated at 2–8°C / 35.6–46.4°F, protected from direct light.
