Hospira Bacteriostatic Water for Injection USP — 30 mL

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.

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

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.

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.

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.

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.

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.

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.

The label sets an in-use period rather than a number of entries — a multi-dose vial may be entered repeatedly within that window under aseptic technique, and is discarded when the period ends or the solution fails inspection, whichever comes first. Inspect before every entry: a vial that is cloudy, discoloured or carries visible particles is not used regardless of dates.

Usually not. Most community pharmacies do not routinely stock multi-dose bacteriostatic presentations, so Australian buyers generally order online. We dispatch from Melbourne, same business day before the 1 pm cutoff, with tracked delivery Australia-wide.

It is labelled as a diluent or solvent — a liquid for preparing compatible medicines that require reconstitution before injection. It is not a ready-to-administer medicine and is never injected on its own. The product information for whatever is being prepared specifies which diluent that product requires.

Bacteriostatic. BAC water is the common shorthand for bacteriostatic water, and you will also see it written as bacteriostatic water for injection, BWFI or bac water — all the same product.

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.

30 mL. It is the manufacturer's 30 mL multiple-dose plastic vial, supplied factory-sealed, and the manufacturer packs it in trays of 25. The manufacturer's label also lists a 20 mL glass presentation, which is not stocked here.

The 30 mL multi-dose vial as a single, in 2-, 3- and 5-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.

No. The manufacturer-labelled vial stocked here is the 30 mL. Bacteriostatic water in 10 and 20 mL multiple-dose vials is stocked under the Aus BAC Supply own label, which is a separate line with its own labelling.

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.

Orders placed before 1 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.
