COA on Every Batch
Sterile & Non-Pyrogenic
The Problem
Your Research Compounds Are Only as Pure as Your Solvent.
02/
The bacteriostatic water market is crowded with products that cut corners. Counterfeit vials, unverified benzyl alcohol concentrations, and untested batches introduce contamination risks that can compromise your entire protocol. Heavy metals, endotoxins, and microbial growth don’t announce themselves — they quietly degrade your results.
Most suppliers test once, if at all. PureBac tests seven times.

THE SOLUTION
SEVEN TESTS. ZERO COMPROMISES
Every single batch of PureBac bacteriostatic water is independently tested across seven critical quality markers before it ships. There is a QR Code linking the Certificate of Analysis on every vial — not as a formality, but as proof.
| TEST | WHAT IT CONFIRMS |
|---|---|
| PURITY | Water meets USP pharmaceutical-grade standards |
| IDENTITY | Benzyl alcohol concentration verified at exactly 0.9% |
| NET CONTENT | Volume confirmed at exactly 3mL or 10mL |
| HEAVY METALS | Screened for lead, arsenic, mercury, and cadmium |
| ENDOTOXINS | Confirmed non-pyrogenic for sensitive applications |
| STERILITY | Absolute absence of microbial contamination |
| VARIANCE (CONFORMITY) | Batch-to-batch consistency verified |

Who Uses PureBac
Built for Researchers Who Can't Afford Uncertainty.
PureBac bacteriostatic water is the reconstitution solvent of choice for researchers. It is equally suited for clinical and compounding applications requiring a reliable, multi-dose sterile diluent. Whether you are running a single experiment or managing a high-volume laboratory,
PureBac gives you the confidence that your solvent is not the variable undermining your work.
Product
Overview
Two Sizes.
One Standard of Purity.
PureBac 3mL
PureBac 10mL
PureBac 3mL Vial Designed for single-compound reconstitution. Minimizes waste and eliminates the need to store a partially used larger vial. Ideal for targeted, short-duration protocols.
PureBac 10mL Vial The standard choice for multi-dose research protocols. Supports up to 28 days of safe, repeated access after the first puncture when stored under refrigeration.
Why Purebac?
We Built PureBac Because We Couldn't Find What We Were Looking For.
The bacteriostatic water available through most online channels lacks transparency. No batch numbers. No accessible COAs. No clear testing methodology. PureBac was created to fill that gap — a supplier that treats quality documentation as a baseline, not a selling point.
Every vial ships with a traceable lot number and a publicly accessible Certificate of Analysis. If you cannot verify what is in your solvent, you should not be using it.

Your Research Deserves a Verified Foundation.
Stop guessing about your solvent. Start every protocol with water you can trust.
