Bacteriostatic Water Certificate of Analysis
Bacteriostatic Water is a sterile diluent rather than a synthesised peptide, so no HPLC purity figure is published for it — chromatographic purity measures a target peptide against its own synthesis impurities, and there is no target peptide here to resolve. What matters instead is what a diluent could introduce into every vial it reconstitutes. It is independently tested for bacterial endotoxin by Ozcanium Analytics, an independent Australian laboratory: below 15.0 EU per vial by kinetic chromogenic LAL, analysed 24 August 2026 on lot APL-BAC10-2608-01, verification code OZ-ENDOTX-4APL. The report is published here in full, as issued.

One report covers every size listed above — it is the same product filled into different vials, so the assay is commissioned per compound rather than per size.
Bacteriostatic Water testing — common questions
- Is Bacteriostatic Water tested?
- Yes. Bacteriostatic Water is independently tested for bacterial endotoxin by Ozcanium Analytics, an independent Australian laboratory: below 15.0 EU per vial by kinetic chromogenic LAL, analysed 24 August 2026 on lot APL-BAC10-2608-01, verification code OZ-ENDOTX-4APL. The report is published on this page as issued, rather than summarised or sent on request.
- Why is there no purity percentage for Bacteriostatic Water?
- Because an HPLC purity figure would not mean anything here. Purity by HPLC is the target peptide's peak area measured against the impurities from its own synthesis — it is a statement about how cleanly a peptide was made. Bacteriostatic Water is not a synthesised peptide, so there is no main peak to integrate and no synthesis impurities to separate from it. The tests that do carry meaning for it are the ones published on this page.
- What does the endotoxin test on Bacteriostatic Water measure?
- Endotoxins are fragments of bacterial cell wall. They are not removed by sterilisation and they provoke a response in cell culture and in-vivo work at very low concentrations, which is why they are measured separately from sterility. The figure matters more for a diluent than for anything else in a research fridge: whatever it carries is added to every vial it reconstitutes, so its endotoxin load is inherited by every experiment downstream of it.
- How do I check the Bacteriostatic Water report is genuine?
- The report carries the laboratory's own reference — OZ-ENDOTX-4APL — printed beside it on this page. Enter that code in the Ozcanium Analytics verification portal and the document is confirmed against their records rather than ours, which is the entire reason a code is published alongside it.
