Public COA audit
Bacteriostatic Water · Benzyl Alcohol 0.9%
Audited September 5, 2026
Several fields check out, but we found issues worth reviewing before you rely on this document.
- Legitimacy
- 92
- Confidence
- 93%
- Panels
- 5/7
- Purity (printed)
- 99.9%
Scored high because the document is mostly consistent but carries soft concerns, broad panel coverage (5/7), and 1 soft concern.

Original certificate
Embedded copy of the stored COA PDF or image. Download it for your records — PeptIQ’s audit is separate from the lab document itself.
7-panel checklist
Had data + good, had data + bad, reported without pass/fail, or missing. Missing lowers thoroughness — you decide whether that panel matters; PeptIQ’s score still factors coverage.
5 of 7 present · 5 passed · 0 failed · 0 reported · 2 missing
Missing is a thoroughness gap — not automatically bad. PeptIQ’s legitimacy score still weighs panel coverage; you can down-weight panels that don’t matter for your use case.
Identity
Tested · passed · core
Compound identity confirmed (e.g. HPLC, mass spec).
Benzyl Alcohol 0.90%, Refractive Index 1.541
Purity
Tested · passed · core
Reported purity percentage for the analyte.
99.9%
Heavy metals
Not on this certificate file
Lead, arsenic, cadmium, mercury, or similar limits.
No evidence on this file. Vendors sometimes publish separate purity and endotoxin reports for the same lot — check the brand page before treating this as “never tested.”
Microbial
Tested · passed
Bioburden / microbial limits testing.
No Growth, Fungi Not Detected
Endotoxin
Tested · passed · core
LAL or chromogenic endotoxin assay.
< 0.10 EU/mL
Sterility
Tested · passed
Sterility testing where applicable.
No Growth
Residual solvent / water
Not on this certificate file
Residual solvents or water content limits.
No evidence on this file. Vendors sometimes publish separate purity and endotoxin reports for the same lot — check the brand page before treating this as “never tested.”
How to read this
Had data · good
Panel present with a pass (or clear acceptance).
Had data · bad
Panel present with a fail — a concrete quality signal.
Had data · unclear
Value reported without an explicit pass/fail mark.
Missing on this file
Not on this certificate file. Lowers file thoroughness; a sibling endotoxin/purity report for the same lot may still exist. PeptIQ’s score still factors coverage.
Findings
Evidence-linked observations from this audit.
High purity confirmed
99.9% purity by GC with impurities < 0.01% or not detected, appropriate for bacteriostatic water preservative testing
Multiple identity confirmations
Benzyl alcohol content verified at 0.90% (within spec 0.9% +/- 10%), refractive index 1.541 matches expected range, appearance confirmed
Comprehensive testing suite
Document includes identity (GC), purity, endotoxin (LAL), sterility/microbial, and pH testing appropriate for bacteriostatic water
Clear batch identification
Lot BAC202603 clearly stated with sample ID KVR-2026-383C6D and access code 9DB8EE
Analysis date provided
Analysis date 06/09/2026 is clearly stated and is on or before current date 2026-09-05
Professional lab presentation
Kovera Labs with verification URL koveralabs.com/verify, professional formatting, QR code for verification, sample photo included
Well-structured report
Clear sections, USP method references, comprehensive data tables, visual vial inspection photo included
Heavy metals not tested
No heavy metals panel present, though this is common for bacteriostatic water testing focused on sterility and preservative content
