Bac water 30ml Hospira is a sterile bacteriostatic water vial for reconstitution. Learn how it works, how to store it, and how it compares to the 10ml size.
Bac water 30ml Hospira is a 30-milliliter vial of bacteriostatic water for injection made by Hospira, a Pfizer company. It contains sterile water with 0.9% benzyl alcohol, a preservative that inhibits bacterial growth so the vial can be punctured multiple times. This size is commonly used to reconstitute peptides, hormones, and other lyophilized powders.
When you search for bac water 30ml, you are looking for a larger multi-dose vial that reduces the need for frequent reordering. The Hospira brand is widely trusted because it meets USP standards for sterility and pH.
What Is Bac Water 30ml Hospira?
Bacteriostatic water is different from plain sterile water. The added benzyl alcohol allows repeated withdrawals from the same vial without immediate contamination. Many suppliers simply call it hospira bac water, and since Pfizer acquired Hospira in 2015, it is also known as pfizer hospira bac water.
Key specifications of the 30ml Hospira vial include:
- Fill volume: 30 milliliters
- Preservative: 0.9% benzyl alcohol
- pH: 4.5 to 7.0
- Sterility: Sterile and non-pyrogenic
- Packaging: Multiple-dose glass vial with rubber stopper
Bacteriostatic water is for injection as a diluent only. It should never be used for intravenous infusion on its own or as a substitute for sterile water when a preservative-free solution is required.
Common Uses for Bacteriostatic Water
The primary use of bacteriostatic water is to dissolve powdered medications and research compounds. In the peptide community, it is often called bac water for peptides because it helps maintain stability and sterility across multiple doses. The product is officially labeled for injection use, meaning it is intended to be injected after a powder is reconstituted.
Typical substances reconstituted with bacteriostatic water include:
- Growth hormone and somatropin
- Peptides such as BPC-157, TB-500, and ipamorelin
- Some vaccines and injectable medications
Bacteriostatic water is not compatible with all drugs. Benzyl alcohol can degrade certain compounds, including some chemotherapy agents and blood products. It is also not recommended for newborns due to the risk of benzyl alcohol toxicity.
Important: Bacteriostatic water is not a treatment for any condition. It is only a diluent, and any substance mixed with it should be used only under the guidance of a licensed healthcare professional.
30ml vs 10ml: Which Size Is Right for You?
The choice between a 30ml and a 10ml vial depends on how much diluent you need and how often you reconstitute. A larger vial offers more doses per purchase, but it must be discarded 28 days after the first puncture. A smaller vial may be more economical if you use it infrequently.
| Feature | 10ml Vial | 30ml Vial |
|---|---|---|
| Total volume | 10 ml | 30 ml |
| Typical 2ml reconstitutions | 5 | 15 |
| Cost per ml | Higher | Lower |
| Shelf life after opening | 28 days | 28 days |
| Best for | Occasional use | Frequent or high-volume use |
For smaller needs, hospira bac water 10ml is a popular alternative that takes up less storage space. If you reconstitute several vials per month, the 30ml size usually provides better value. However, never use a vial beyond 28 days after the first needle entry, even if it still looks full.
How to Store and Handle Bac Water 30ml Hospira
Proper storage keeps bacteriostatic water safe and effective. Follow these guidelines:
- Store the unopened vial at controlled room temperature between 20°C and 25°C (68°F to 77°F).
- Do not freeze bacteriostatic water. Freezing can damage the vial and compromise sterility.
- Protect the vial from light, which can degrade the preservative over time.
- After the first use, you may refrigerate the vial, but bring it to room temperature before drawing up a dose.
- Swab the rubber stopper with an alcohol pad before each puncture.
- Use a new sterile needle and syringe every time to avoid contamination.
- Write the date of first use on the label. Discard the vial 28 days after that date.
Inspect the solution before each use. If it is cloudy, discolored, or contains particles, discard it immediately. Always check the expiration date on the vial.
Safety, Legal, and Buying Considerations
Bacteriostatic water for injection, USP, is an FDA-approved prescription product. However, many online vendors sell it as a research chemical, which means it is not intended for human use. If you plan to inject any reconstituted substance, you should do so only under medical supervision.
When buying, look for authorized medical suppliers or pharmacies. Some shoppers search for bac water walmart to find local pickup options, but Walmart's online marketplace typically lists 10ml vials from third-party sellers rather than the 30ml Hospira product. Always verify the seller's reputation and check for a valid expiration date.
Benzyl alcohol can cause serious reactions in neonates, including gasping syndrome. Bacteriostatic water should never be given to newborns. Pregnant or breastfeeding women should consult a doctor before using any injectable product.
Final Thoughts
Bac water 30ml Hospira is a convenient multi-dose diluent for reconstituting peptides and other powdered medications. Its 30ml size reduces how often you need to reorder, but it must be discarded 28 days after the first puncture. Choose the 10ml size if you reconstitute infrequently or want less waste.
Always store bacteriostatic water at room temperature, protect it from light, and follow strict sterile technique. Most importantly, consult a licensed healthcare professional before injecting any substance. Bacteriostatic water is only a diluent—it does not treat, cure, or prevent any disease.
