About BAC Water 10 mL
Bacteriostatic water is plain water carrying an added preservative, used to dissolve a freeze-dried peptide and drawn from more than once. This is the 10 mL BAC Water vial, the larger of two, listed as 82578.
Chromatography has nothing to measure in water; the 10 mL lot is logged instead.
Australian Research Peptides lists the 10 mL vial in Lab Supplies as a laboratory consumable, not for human or veterinary use.
Bacteriostatic water — BAC water on the vial label — is plain water carrying an added preservative. Bacteriostatic means it stops bacteria multiplying rather than killing them outright, which is what bactericidal would mean. That single ingredient is the whole difference between this and unpreserved laboratory water, and it is why a vial can be drawn from on several occasions. The US compounding standard USP 797 gives a punctured vial of that kind 28 days.
ARP's bacteriostatic water is preserved with benzyl alcohol at 0.9 per cent, or 9 mg per mL, as stated by its supplier. That matches the published USP standard for bacteriostatic water, which uses the same preservative at the same strength.
No chromatography applies to water, so this line carries no purity certificate; its grade is Sterile Filtered instead. It sits in Lab Supplies rather than with the peptides, and every quantity on this page is a millilitre figure.
Australian Research Peptides lists bacteriostatic water in Australia in two volumes, 3 mL and 10 mL — nothing larger, and no 5 mL. It is posted to every state and territory including Perth, Melbourne, Brisbane and Adelaide, and is searched under many spellings — bac water, bacteriostatic water, bacterio static water, bacstat water — all the same preserved diluent. It is stocked as a laboratory consumable beside the syringes rather than with the peptides, and it is not supplied for human or veterinary use. Being water rather than a peptide, it carries no purity certificate.

Questions about BAC Water 10 mL
This BAC Water 10 ml question guide from Australian Research Peptides is specific to the exact listing, with live buying details, size comparisons, concentration calculations, storage, testing and the inherited product background grouped separately. Start with the quick answers or jump to the topic you need.
Exact strength, quantity and listing fit
Four 3 mL BAC Water vials cost $63.96; one 10 mL vial is $22.99 — $40.97 less, and three fewer vials to store.
Yes — BAC Water 10 mL is $2.30 a millilitre against $5.33 for the 3 mL. It holds 7 mL more for $7.00 more.
Ten millilitres — more than three times the smaller listing. The liquid is identical; only the fill volume changes, so one 10 mL vial covers what three 3 mL vials would and leaves a millilitre over.
Ten millilitres beats nine, and it arrives under one seal instead of three. The per-millilitre figure on each page shows which is cheaper; fewer stoppers pierced and fewer part-used vials is the other half.
Several peptides at once, a large-format vial such as a hundred-milligram or seventy-milligram listing, or any run wanting a weaker solution where the volume required climbs past three millilitres.
It can be. Making up one ten-milligram vial takes a millilitre and leaves nine behind, with a stopper pierced months before the rest is wanted. The smaller listing exists for exactly that case.

Reconstitution and concentration calculations
Bacteriostatic water is made of sterile water with a single thing added to it: an antimicrobial preservative, and nothing else at all. There is no salt, no buffer, no sugar and no peptide in the vial. Pfizer's published product label for the USP bacteriostatic water preparation, the reference product of this type, gives 9 mg of benzyl alcohol in every millilitre, and names an 11 mg per millilitre presentation, or 1.1 per cent, beside it. Australian Research Peptides' own vials carry benzyl alcohol at 0.9 per cent (9 mg per mL), as stated by its supplier: the lower of the two strengths on that label.
A 3 mL BAC water vial suits one or two standard 10 mg peptide vials and is the usual first purchase, and it is the volume the bundles carry. The 10 mL suits a large-format vial such as 100 mg GHK-Cu, an 80 mg KLOW or a 70 mg GLOW, or several peptides at once. One 10 mL replaces more than three 3 mL vials, so fewer seals are broken and fewer lots need tracking, and it works out cheaper per millilitre. Either way the clock starts at the first puncture, not at delivery, so the larger vial only pays if it is used inside that window.
An unopened Bacteriostatic Water vial belongs at room temperature and out of direct light, and putting it in the fridge achieves nothing. The preservative in it does the work that cold would otherwise have to. Refrigeration is a rule about reconstituted peptide, and it gets misapplied to the diluent constantly.
Bacteriostatic Water keeps for around 28 days from first puncture, which is the conventional working limit and the period USP 797 — the United States compounding standard for sterile preparations — sets for a vial that is entered more than once. The preservative is what suppresses bacterial growth between entries, and that protection is not indefinite. Write the date on the vial when the seal is first broken, wipe the stopper each time, and discard it if the solution stops being clear.
Bacteriostatic Water is stored at room temperature and not frozen, unlike the lyophilised peptides it is used to reconstitute. Keep the unopened vial out of direct light. Australian Research Peptides' stated condition for this grade is room temperature, then refrigeration after opening. The USP bacteriostatic water label gives 20 to 25 degrees Celsius. Discard any vial that has turned cloudy or shows particles.
Seven millilitres. Drawing three for one large peptide vial leaves seven behind — enough for seven single-millilitre make-ups, or three more at two millilitres with one millilitre to spare.
Product identity and research background
Both are search terms for the same product. 'Backwater for peptides' and 'bacwater' are frequent misspellings of BAC water, so anyone typing 'backwater peptides' or 'peptide water Australia' is looking for Bacteriostatic Water. Bacteriostatic Water, shortened to BAC water or just bac, is the correct name: sterile water carrying a preservative. It is the standard diluent for taking lyophilised peptide powders into solution for research work, and Australian Research Peptides posts the sealed vial from within Australia.
Bacteriostatic Water is preserved water used as the liquid that dissolves a freeze-dried peptide before laboratory work. Peptides arrive as a dry cake with no liquid in the vial. Adding the water turns that solid into a solution at the concentration the work calls for, and the preservative allows the resulting vial to be drawn from more than once.
Bacteriostatic Water works by carrying a preservative that keeps microbial numbers from climbing between withdrawals. That is what makes repeated entry into one vial reasonable. It is not the same as sterilising. Anything already present is held in check rather than destroyed, so a vial still deserves clean handling. The label for the USP preparation describes repeated withdrawals from a single container.
Storage, condition and testing
Bacteriostatic Water is sold by volume, so millilitres are the honest unit for it. The peptides are dry solids sold by mass, which is why those pages read in milligrams. Australian Research Peptides records the unit against each product rather than assuming one for the whole catalogue. A milligram figure on a liquid would describe nothing a buyer could act on.
More questions
Sound bacteriostatic water is clear, colourless and free of anything visible. The signs it should not be used are haziness, floating or settled particles, any tint at all, and a stopper or seal that is cracked, lifted or weeping. A preservative restrains bacterial growth between withdrawals but does not keep a punctured vial sterile forever, and repeated entries without wiping the closure shorten what protection there is. Contamination can also leave the liquid looking unchanged, which is why the date of first puncture matters as much as appearance.
Bacteriostatic Water goes into the peptide vial slowly, running down the inside of the glass. Aim it away from the powder rather than straight onto the cake. Swirl or roll the vial gently until the liquid turns clear. Never shake it, because shaking foams a peptide solution. Let a cold vial reach room temperature first, so moisture does not condense on the powder.
At 1 mL per 10 mg peptide vial, a 3 mL Bacteriostatic Water vial covers three of them and a 10 mL covers ten. Using 2 mL per vial halves both figures. The real limit is usually time rather than volume, because a punctured water vial has a working life once its stopper is first pierced.
Bacteriostatic Water is the standard diluent for every lyophilised peptide Australian Research Peptides sells, from a 10 mg BPC-157 vial to a 100 mg GHK-Cu one. What changes between them is the volume, not the diluent.
Bacteriostatic Water has no single right volume, and Australian Research Peptides publishes none for any of its listings. What the volume changes is how concentrated the resulting solution is, never how much peptide is in the vial. It is sold in 3 mL and 10 mL, and which suits an order depends on how many vials it has to cover.
Bacteriostatic water is sold in Australia as an ordinary laboratory consumable, and Australian Research Peptides supplies it to laboratories and researchers on that basis. It is not supplied for human or veterinary use, which is the boundary that matters more than the paperwork. ARP publishes no scheduling or registration position for this line, and nothing here is legal advice; a laboratory carrying an obligation of its own should confirm it independently rather than read it off a product page.
Bacteriostatic Water is preserved water, and that single difference explains all three products. Plain sterile water carries no preservative, so it is packaged for one use and discarded after a single entry. Bacteriostatic saline carries a preservative too, but its base is a salt solution rather than plain water. Australian Research Peptides lists the plain preserved water only and does not resell a saline version.
No, Bacteriostatic Water from Australian Research Peptides is not the Hospira product, and ARP does not resell it. ARP supplies its own sterile-filtered vials in 3 mL and 10 mL. Different suppliers, different products.
Sterile water used in place of bacteriostatic water carries no preservative, so once its stopper is pierced there is nothing suppressing bacterial growth in what remains. The USP preparation of bacteriostatic water is labelled at 0.9% benzyl alcohol, which is what makes a vial usable across multiple withdrawals rather than once. Tap or distilled water is not sterile at all and is not a substitute for either.
The two Bacteriostatic Water listings hold 3 mL and 10 mL of the same liquid. Formulation, filtration, glass and preservative are identical across both. Only the amount in the vial changes. The pair exists so that a small working quantity or a larger one can be ordered without buying two vials of the same size.
A chemist, Chemist Warehouse included, is a different supply route from Australian Research Peptides: a retail pharmacy dispenses sterile-water products for approved medical use, while ARP supplies bacteriostatic water as a laboratory consumable. That is a different purpose and a different route, so the two are not interchangeable even where the contents read alike. ARP lists it beside the research vial it reconstitutes, dispatched in the same parcel.
