Buy Bacteriostatic Water in Australia

Buy bacteriostatic water in Australia from Macropus Peptides, the standard diluent for reconstituting lyophilised research peptides. Each sealed vial contains sterile water with a small amount of benzyl alcohol as a preservative, which holds back bacterial growth so the vial can be punctured several times over the life of a study. Choose the 3mL vial for a single peptide vial, the 10mL vial for several, or the 30mL bottle for a whole study, all priced and ready to order. Every label carries product, volume, lot number and storage conditions, and a certificate of analysis is available for each lot. The preservative is benzyl alcohol at 9 mg per millilitre, the standard bacteriostatic formulation used in laboratories worldwide. Most customers add BAC water to the same order as their peptides, so diluent and peptide arrive together, dispatched from within Australia to Perth, Melbourne, Brisbane, Adelaide and every other Australian address. Supplied for in-vitro laboratory research only, to purchasers aged 18 and over; not for human or veterinary use.

Buy Bacteriostatic Water Australia: 3mL and 10mL Vials

Macropus Peptides supplies bacteriostatic water in two vial sizes, 10mL and 3mL, as the everyday diluent for reconstituting freeze-dried research peptides. Of everything in our lab supplies range, this is what peptide buyers add to their carts most, because almost every lyophilised vial needs a clean, preserved liquid before it can be used in the laboratory.

What is bacteriostatic water

Bacteriostatic water is sterile water that contains a small amount of benzyl alcohol, typically 9 mg in every millilitre. The benzyl alcohol does not kill bacteria outright; it stops them multiplying, which is what bacteriostatic means. That preservative is the key difference from plain sterile water: a vial can be punctured, closed and used again over days or weeks without the contents becoming a growth medium. It is colourless, has a faint characteristic smell from the preservative, and is supplied in sealed glass vials with a rubber septum so liquid can be drawn without opening the vial.

How bacteriostatic water works for peptides

Research peptides are shipped as lyophilised powder because they are far more stable dry than in solution. To use one, a laboratory adds a measured volume of diluent, which sets the stock concentration: 2 mL added to a 10mg vial, for example, gives 5 mg per mL. BAC water suits this job because the preservative protects a peptide stock that will be drawn from repeatedly, and because its near-neutral character dissolves most peptides cleanly. A few peptides are exceptions. Those that aggregate at neutral pH, such as IGF-1 LR3, are usually reconstituted in dilute acetic acid instead, so always check the peptide's own datasheet first.

Bacteriostatic water research: what the standards show

The product is defined by pharmacopoeial standards rather than clinical trials. The United States Pharmacopeia monograph describes it as sterile water containing one or more suitable antimicrobial agents, packaged for multiple withdrawals, and sets the tests it must pass. The wider science of preservatives is reviewed in a 2007 Journal of Pharmaceutical Sciences paper on antimicrobial preservatives in parenteral products, which explains why benzyl alcohol became one of the most widely used preservatives, and also notes that it can encourage some proteins to aggregate, one reason acid diluents exist for sensitive peptides. Both sources are listed in our bacteriostatic water research library.

Bacteriostatic water vial specifications

Each vial is glass, sealed with a rubber septum under a crimped cap, and labelled with product name, volume, lot number and storage conditions. The lot number is your reference for the matching certificate of analysis. Keep unopened stock on a shelf at room temperature, out of sunlight.

Bacteriostatic water price in Australia

Our 10mL bottle is listed at a set Australian dollar price and ships as soon as you order. All three sizes carry a set price. For most laboratories one of the larger vials is the better buy, since a single bottle reconstitutes several peptide vials.

Bacteriostatic water 10ml: where to buy in Australia

The 10mL vial is our standard size and the one most researchers search for. Ten millilitres stretches across five peptide vials if each takes 2 mL, so a single bottle usually covers a whole order of peptides. It is priced, in stock and ships in the same parcel as the peptides it will be used with.

Bacteriostatic water 3ml: the small vial for single reconstitutions

This smaller bottle is meant for labs mixing just one or two peptide vials, so no half-used diluent lingers on the bench. Less liquid left over means fewer punctures and less time for the preservative to be tested. It is priced and ready to order alongside the larger sizes.

Bacteriostatic water 30ml: the bulk bottle for long studies

The 30mL bottle suits groups that reconstitute many vials over several weeks, or that run parallel studies from one lot of diluent. Buying the larger volume lowers the cost per millilitre and keeps every vial in a study on a single documented lot of water. Because the bottle is punctured repeatedly, work with a clean technique, swab the stopper each time and record the date of first puncture on the label.

Where can I buy bacteriostatic water in Australia

• Direct from Macropus Peptides, in 10mL and 3mL vials
• A fixed price on every size: 3mL, 10mL and 30mL
• Lot number on every label and a certificate of analysis per lot
• Shipped with your peptides from local Australian stock, so there is no separate delivery to wait for
• Acetic acid available in the same order for peptides that need it

How to order bacteriostatic water online

• Add the 3mL, 10mL or 30mL size to your cart
• Add the peptides you plan to reconstitute
• Include dilute acetic acid if any peptide calls for it
• Pay, confirming the purchase is for adult lab work
• Keep the lot number on file in case you need the certificate

Bacteriostatic water vs sterile water: which to buy

The two are not the same. Sterile water contains nothing but water and is intended for a single use: once the seal is broken, any leftover should be discarded because nothing stops bacteria growing in it. BAC water contains the benzyl alcohol preservative, so the same vial can be used for repeated withdrawals. For peptide work that means one bottle can prepare several vials over a period of weeks, which is why it is the default choice. Sterile water is only preferred where a protocol specifically excludes preservatives. The concentration calculator on each peptide listing works with either diluent.

How long does bacteriostatic water last

Sealed vials keep until the expiry date on the label when stored at room temperature and out of direct light. Once the septum has been punctured, multi-use vials are commonly used within 28 days, or as the label directs, and many laboratories keep an opened vial in the refrigerator to be safe. Refrigeration is not required before opening. Throw out a vial that goes cloudy, grows specks or reaches its expiry, and draw with a new sterile needle every time so the preservative is never overloaded.
