Bacteriostatic Water 10ml

Bacteriostatic Water 10ml in Australia and New Zealand: a peptide reconstitution solvent from GreenLabs AU

Bacteriostatic water, or bac water, is the liquid most laboratories reach for to bring a freeze-dried research peptide back into solution. GreenLabs AU stocks it in Australia and New Zealand as a sealed 10ml vial in our Peptide Research Essentials range, for in-vitro (test-tube) laboratory research only. It is not a medicine, and it is not for people or animals.

Bacteriostatic water 10ml: quick overview

• What it is: bacteriostatic water (bac water), a sterile research solvent that dissolves freeze-dried peptides, preserved with benzyl alcohol so one vial serves many samples.
• Sizes: this 10ml vial at $20, with a 3ml option for smaller jobs.
• Testing: benzyl alcohol level checked by the independent lab Janoshik, with a Certificate of Analysis per batch.
• Delivery: same-day dispatch from Sydney, free express over $200.

What goes into bacteriostatic water?

Bacteriostatic water is mostly purified water, with a small amount of benzyl alcohol added as a preservative (a substance that stops bacteria from growing). The name says it: “bacteriostatic” means holding bacteria still, so they cannot multiply in the sealed vial.

How bacteriostatic water reconstitutes research peptides

Research peptides usually ship as a freeze-dried powder and cannot be studied until they are liquid again. This is the everyday job of bacteriostatic water for peptides: a researcher adds it to the vial, the powder dissolves, and a clear, stable solution is ready for the bench. Because the preservative keeps it clean between uses, one 10ml vial can prepare one peptide after another, from recovery compounds such as BPC-157 to metabolic ones such as MOTS-C, all as in-vitro bench work.

Bacteriostatic water vs sterile water: the difference

A common question is how bacteriostatic water differs from plain sterile water, since both begin as pure, sterile water. The difference is the benzyl alcohol. Sterile water has no preservative, so once opened it is meant for a single use. Bacteriostatic water resists bacteria, so the same vial can be returned to across several sessions, which makes it the sensible choice whenever a peptide solution must hold up beyond one sitting.

Bacteriostatic water or acetic acid water: choosing the right solvent

Bacteriostatic water handles most research peptides, but a handful are harder to dissolve and need a mildly acidic liquid. For those, laboratories turn to acetic acid water, a 0.6% acetic acid solution (the acid found in vinegar). Start with bacteriostatic water and keep acetic acid water ready for the peptides that will not dissolve in it.

Is bacteriostatic water a medicine? Research-use status

No. The bacteriostatic water on this page is a laboratory material, not a medicine, supplement or cosmetic, and it carries no approval from the TGA (Australia’s medicines regulator) or the FDA for any use in the body. GreenLabs AU supplies it to qualified researchers only, and nothing here is medical advice. By ordering, you agree to handle it under proper laboratory conditions and within Australian and New Zealand law.

How GreenLabs AU tests its bacteriostatic water

With a solvent, quality is about what is really inside the vial, so GreenLabs AU sends its bacteriostatic water to Janoshik, an independent third-party laboratory. The benzyl alcohol content, the one active part of the product, is measured and confirmed. The matching Certificate of Analysis (CoA, the lab’s signed report for that batch) is published on our certificate page, so you can match your vial to its own result before you buy.

Storing bacteriostatic water and keeping it clean

• Keep unopened vials somewhere cool and dry, below 25°C and out of direct sunlight.
• Before each use, wipe the rubber top with an alcohol swab so nothing enters the vial.
• The preservative lets an opened vial keep working for a while; most labs set it aside about 28 days after first use.
• If the liquid turns cloudy or changes colour, throw the vial out rather than using it.

Bacteriostatic water FAQs

What is bacteriostatic water?

It is sterile, purified water with a small amount of benzyl alcohol added to hold bacteria back. That preservative is why one vial can be opened and used more than once. GreenLabs AU sells it as a 10ml vial for laboratory research.

What is bacteriostatic water used for?

In the lab, it is used to turn freeze-dried research peptides back into a usable liquid. It is the usual solvent for peptide work, and it is used only in research, never on people or animals.

How is bacteriostatic water different from sterile water?

Both start as sterile water. The difference is that bacteriostatic water contains benzyl alcohol, so it resists bacteria and can be used several times, while sterile water has nothing added and is meant to be used once after opening.

How long does bacteriostatic water last once opened?

Unopened and stored well, it lasts until the date on the vial. After the first use, the preservative keeps it good for a while, and most labs stop using the vial around 28 days later, or sooner if it looks cloudy or changes colour.

Does bacteriostatic water need to be refrigerated?

A sealed vial does not. A cool, dry place below 25°C and away from sunlight is enough. Just wipe the rubber top with alcohol before each use to keep it clean.

Where can I buy bacteriostatic water in Australia and New Zealand?

You can order it online from GreenLabs AU. We ship across Australia and New Zealand, so there is no need to look for it locally or “near me.”

Is bacteriostatic water safe for human or animal use?

No. It is supplied for laboratory research only. It is not a medicine, and it must not be used in people or animals.

Disclaimer: GreenLabs AU supplies bacteriostatic water for in-vitro laboratory research only. It is not a medicine, a supplement or a cosmetic, and it is not for use in humans or animals. By placing an order, you confirm you are a qualified researcher and that you will store and use the product in line with all applicable Australian and New Zealand laws.
