Overview

This is an original manufacturer presentation of bacteriostatic water (BAC water), manufactured by Hospira. Aus BAC Supply keeps the manufacturer seal, vial and label unchanged.

Bacteriostatic water is commonly shortened to BAC water; both names describe this same product.

It is a diluent or solvent—not a ready-to-administer medicine. The supplied product information determines compatibility, preparation, route, handling and storage. Clinical decisions and administration must be directed by a qualified healthcare professional.

Never inject a diluent by itself or use it outside the manufacturer instructions.

The 0.9% figure on the label is the benzyl alcohol concentration — 9 mg per mL — and it is the whole reason this presentation exists in a multi-dose vial at all. Benzyl alcohol is a bacteriostatic agent: it inhibits the growth of most common bacteria rather than sterilising anything, which is what allows a sealed vial to be entered more than once instead of being discarded after a single withdrawal. Preservative-free sterile water has no such agent, and its vial is labelled for one withdrawal for exactly that reason.

That protection is finite rather than open-ended. A printed expiry governs the sealed vial, and a separate, much shorter in-use period begins the moment the stopper is first entered — whichever falls first ends the vial's usable life. Both figures come from the product information supplied with the vial, not from a general reference.

What you receive is the manufacturer's own 30 mL glass multi-dose vial with its flip-off closure and crimp intact, manufactured under pharmaceutical GMP and released against the Bacteriostatic Water for Injection USP monograph — a specification covering identity, sterility, preservative content, particulate limits and a controlled pH range, with a lot number and expiry traceable to that release. Aus BAC Supply does not decant, repackage or relabel. That distinction is the point: water of unclear origin transferred into an unmarked container has none of the documented manufacturing behind it, however similar it looks in the vial.

Available as a single vial, in 2- and 3-vial packs, and in manufacturer trays of 25 and 50. Unopened vials keep until their printed expiry, so buying several at once lowers the unit price without shortening anything — each vial's in-use period starts only when that particular vial is opened.

Aus BAC Supply is an independent retailer and is not affiliated with, endorsed by or an authorised distributor of the manufacturer; the name identifies the genuine factory-sealed product supplied.

FAQ

What is this presentation for?

It is labelled as a diluent or solvent for compatible medicines that require preparation before injection. It is not a ready-to-administer medicine and must not be injected by itself.

Has Aus BAC Supply changed the product?

No. We keep the original manufacturer seal, vial and label intact and do not decant, repackage or relabel it.

What is bacteriostatic water?

Sterile water containing 0.9% (9 mg/mL) benzyl alcohol as a bacteriostatic preservative. The preservative inhibits the growth of most common bacteria, which is what allows a sealed multi-dose vial to be accessed repeatedly rather than discarded after a single withdrawal.

Is BAC water the same as bacteriostatic water?

Yes. BAC water is simply the common abbreviation. You may also see it written as bacteriostatic water for injection, BWFI or bac water — all describe the same product.

How is it different from sterile water?

Sterile water carries no preservative, so its vial is labelled for a single withdrawal and should not be re-entered. Bacteriostatic water adds 0.9% benzyl alcohol, which holds bacterial growth in check after the seal is broken and is what makes a multi-dose presentation possible.

How is it different from bacteriostatic saline?

Both are preserved with benzyl alcohol and both are multi-dose vials. Bacteriostatic saline is isotonic 0.9% sodium chloride; bacteriostatic water contains no solute. The manufacturer information for the product being prepared specifies which diluent it requires.

What does the 0.9% refer to?

The benzyl alcohol concentration — 9 mg per mL. Note that on a bacteriostatic sodium chloride label the 0.9% refers to the salt instead, which is a common source of confusion between the two products.

How long does a vial last once opened?

A fixed in-use period applies from first entry, and it is much shorter than the printed expiry on the sealed vial. The figure stated in the product information supplied with your exact vial is the one that governs, and whichever date falls first ends the vial's usable life.

Does it need to be refrigerated?

Follow the storage conditions printed on the vial and in the supplied manufacturer product information. Storage conditions do not extend the in-use period once a vial has been entered.

What sizes and pack quantities are available?

The 30 mL multi-dose vial as a single, in 2- and 3-vial packs, and in manufacturer trays of 25 and 50. Every option is the same factory-sealed vial — the pack size is simply how many you receive.

Is it manufactured to a standard?

Yes. It is produced under pharmaceutical GMP and released against the Bacteriostatic Water for Injection USP monograph, which sets a controlled pH range alongside identity, sterility, preservative content and particulate limits.

How fast is delivery in Australia?

Orders placed before 2:00 pm Melbourne time on a business day are dispatched the same business day, tracked Australia-wide. Express typically arrives within 1–3 business days and Standard within 2–6 after dispatch; estimates are a guide and are not guaranteed. Express is free on orders over $150.
