How to Store Bacteriostatic (BAC) Water — Temperatures, Do’s & Don’ts, and the Best BAC Cases

Bacteriostatic water (“BAC water”) is commonly packaged in 30 mL bottles used to dilute or reconstitute medications. Safe storage protects potency and helps you maintain a clean workflow. This guide explains where to keep BAC water, what temperatures to avoid, and which cases neatly hold a 30 mL bottle alongside your vials and supplies.

Storage Temperature: Room Temp, Not Freezer

In general, BAC water is stored at controlled room temperature, away from heat and direct sunlight. Do not freeze BAC water. Refrigeration is typically not required unless your product label specifically instructs otherwise. Always follow the instructions on your bottle label and any guidance from your pharmacist.

Why a Dedicated BAC Case Helps

A case that holds a 30 mL BAC bottle plus small vials, alcohol pads, and syringes keeps your workspace tidy and reduces the risk of spills or cross‑contamination. Look for rigid shells, foam that grips bottles upright, and a separate compartment for clean accessories. If you travel, a compact case also makes inspections easier because everything is labeled and organized.

Tips for a Clean, Consistent Workflow

• Store BAC water at room temperature in a dark cabinet or drawer.
• Keep the 30 mL bottle upright in a foam slot; avoid rolling or tipping.
• Separate clean pads/needles from used items; add a small sharps solution for travel.
• Label dates and contents clearly; keep prescription labels intact.
• If your label requires cold storage for related vials, use insulated cases with gel packs — never place glass directly against ice.
