Introduction
Not all bacteriostatic water is created equal. For labs, the difference between a low-quality supplier and a lab-grade, GMP-tested product can mean the difference between reliable results and compromised experiments.
This article explains what makes bacteriostatic water “lab-grade quality,” why Certificates of Analysis (COAs) matter, and how to ensure you’re buying from a trusted European supplier.
(Reminder: Herbilabs products are for Research Use Only (RUO) — not for human or veterinary use.)
What Does “Lab-Grade Quality” Mean?
Lab-Grade Quality bacteriostatic water is manufactured and packaged under strict quality standards:
- Sterility: Verified through microbial testing.
- Composition Accuracy: 0.9% benzyl alcohol content confirmed.
- Endotoxin Testing: Ensures absence of harmful bacterial by-products.
- pH Balance: Controlled for consistency across batches.
Why Certificates of Analysis (COAs) Matter
A trustworthy supplier provides a COA for each batch. A COA verifies:
- Sterility results
- Endotoxin levels
- pH measurements
- Benzyl alcohol concentration
This transparency gives labs confidence that every vial meets the same standards.
Risks of Low-Quality Suppliers
- Unverified sterility → higher contamination risk
- Poor packaging → cracked vials, leaking stoppers
- Lack of testing → uncertainty about benzyl alcohol concentration
- No documentation → difficult for labs to meet compliance standards

FAQ
What’s the difference between lab-grade quality and medical-grade?
Lab-grade products are RUO (Research Use Only). Medical-grade requires additional regulatory approvals for human use.
Can I get a COA for my order?
Yes, Herbilabs provides batch-specific COAs for transparency.
Do all suppliers provide COAs?
No. Many low-cost suppliers do not — always verify before buying.
Compliance Reminder
Herbilabs bacteriostatic water is supplied strictly for Research Use Only (RUO). It is not intended for human or veterinary use.
Conclusion
Lab-grade bacteriostatic water ensures consistency, sterility, and safety in research workflows. Always buy from suppliers who provide transparent COAs and GMP-backed testing.
