Pharmaceutical grade, 0.9% benzyl alcohol, batch documented on request. Single use ampules for one-off reconstitutions, multi-dose vials for ongoing work. From a Perth shelf, not a warehouse overseas.
The benzyl alcohol percentage and the sterility assurance. Ours is pharmaceutical grade at exactly 0.9%, sealed at manufacture, and every batch we hold is documented and available on request.
If a seller will not show you batch paperwork, that tells you something. We send it whenever you ask, before or after the order.
Batch documentation matters for another reason too. If a study result ever needs to be rechecked, you want to know exactly which batch of diluent sat in that vial. Ours are traceable to the unit we ship.
Follow the reconstitution guide to pair your diluent with the right draw volume, and keep pen kit supplies on hand for repeat dosing protocols.
The 10mL ampule is the honest choice for one-off work. Break the seal, reconstitute one vial, discard the rest. No arguments about contamination.
The 30mL vial exists for repeated withdrawals. The benzyl alcohol slows growth between entries, which is why multi-dose research use depends on it.
If your protocol draws daily, one 30mL vial beats five ampules on cost and convenience. If you reconstitute rarely, ampules win on freshness every time.
Every batch is documented and available on request.
Room temperature, out of light, unopened. After first entry, refrigerate, swab the stopper every time, and use within the manufacturer window. Cloudy or particulate? Discard it. No exceptions.
A single reconstitution with a 10mL ampule covers one lyophilised vial in most cases. A 30mL multi-dose vial covers weeks of daily draws and stays stable because the benzyl alcohol preservative keeps the solution usable between entries. The 5x10mL pack is the right call for a team that runs several studies per month but wants each reconstitution to open a fresh, sealed ampule.
When in doubt, start smaller. An open vial you do not finish is waste; a sealed ampule you keep for next week is not.
Pair bac water with the Essential Starter Kit or Full Stack Pack for syringes and swabs, or the Sanofi Allstar pen kit for repeat dosing.

It is the preservative that makes multi-dose use possible. It inhibits bacterial growth after the seal is broken. Without it, a punctured vial is single use.
One-off reconstitution, 10mL ampule. Daily draws, 30mL vial. Running several studies, 5x10mL pack, saves $5.
No. We supply research consumables only, no medical claims, no compounds.
Refrigerated and swabbed each use, within the manufacturer window on the vial. Most researchers finish a 30mL vial well inside that.
