Hospira BAC Water (30mL) carries the manufacturer's own lot marking on the vial rather than a Certificate of Analysis from our testing lab. The peptide panel describes compounds, not solvents, so none is claimed here.
Certificates we have publishedWhat it is
Bacteriostatic water is sterile water containing 0.9% benzyl alcohol as a bacteriostatic preservative, which is what allows a vial to be entered more than once rather than being spent on a single draw. This listing is the Hospira-manufactured version in a 30 mL multi-dose vial, the presentation most commonly kept on hand as a general-purpose laboratory diluent.
Every lyophilised compound in this catalogue arrives as a dry powder and cannot be worked with until it is reconstituted — the powder has to be brought back into solution with a sterile solvent before anything can be measured, diluted or transferred. That solvent is never included with a compound order. If this is a first order, a vial of bacteriostatic water is what makes the rest of it usable.
How it's used in the lab
There is no research programme behind a solvent — the relevant context here is practical. Bacteriostatic water is the default choice for reconstituting lyophilised material on the bench. The benzyl alcohol is a preservative rather than an active ingredient: it suppresses microbial growth inside the vial so the same container can be entered repeatedly over a period of use, which is the working difference between it and single-use sterile water.
The Hospira vial is a stoppered multi-dose presentation, and standard handling applies — wipe the stopper before each entry, use a fresh sterile needle each time, and keep the vial capped and away from light between uses. The volume of solvent added is what determines the concentration of whatever is reconstituted, so that calculation belongs before the vial is opened. This listing supplies solvent only; no compound is included.
Questions
What is bacteriostatic water for?
Reconstitution. Lyophilised compounds ship as a dry powder and have to be returned to solution before anything can be measured, diluted or transferred. Bacteriostatic water is the standard solvent for that step.
Why bacteriostatic rather than plain sterile water?
The 0.9% benzyl alcohol suppresses microbial growth inside the vial, so a multi-dose container can be entered more than once. Plain sterile water carries no preservative and is a single-use presentation.
How is it supplied and stored?
One sealed 30 mL stoppered multi-dose vial. Store at room temperature away from direct light, keep it capped between entries, and observe the expiry date printed on the vial.
Is solvent included with a peptide order?
No. Solvent is always a separate line item, and every lyophilised compound in the catalogue needs some before it can be worked with — so it is worth adding a vial before checkout.
