How It Works
A simple 3-step process for your research workflow.

1. Receive & Verify
Check the vial, lot number and COA to confirm authenticity.

2. Use in Your Workflow
Incorporate the solution according to your laboratory's validated procedures and protocols.

3. Document & Store
Record the lot number in your lab notes and store sealed vials at room temperature, away from light.
Support your research with confidence
Four reasons researchers choose our bacteriostatic water for dependable reconstitution.
Bacteriostatic Protection
Formulated with 0.9% benzyl alcohol so a single vial supports repeated, low-risk withdrawals in the lab.
Type I Borosilicate Glass
Chemically resistant borosilicate vials protect solution integrity and minimize leaching.
Batch-Tested Purity
Every lot is independently tested for pH, benzyl alcohol content, and recovery before release.
Research-Ready Consistency
Neutral pH and verified composition give you a reliable, repeatable diluent run after run.
The benchmark for reliable
research materials
Four non-negotiables built into every research vial — the details that separate research-grade materials from the rest.

- 01
0.9% Benzyl Alcohol
A bacteriostatic diluent that supports multiple withdrawals while limiting microbial growth.
- 02
30 mL, Multi-Dose Vials
Type I borosilicate glass vials sized for repeated reconstitution across a research workflow.
- 03
Batch-Tested & Verified
Independently tested for pH, benzyl alcohol content, and recovery, with a Certificate of Analysis per lot.
- 04
Research-Grade Consistency
Neutral pH and verified composition for dependable, repeatable results.
Not all reconstitution solutions are equal
See how sealed, batch-tested vials compare to the alternatives researchers often settle for.
Unverified Bulk Water
- Composition not batch-verified
- No Certificate of Analysis
- Risk of contamination between draws
Our Bacteriostatic Water
- 0.9% benzyl alcohol supports repeat draws
- Independently verified per lot
- Type I borosilicate, sealed & consistent
Plain water
- No bacteriostatic protection
- Single-draw once opened
- Not suited to multi-dose reconstitution

Four things we refuse to
compromise on
Every decision behind our materials comes back to these four fundamentals of dependable research materials.
Purity Matters
0.9% benzyl alcohol in purified water, batch-tested for consistent bacteriostatic performance.
Packaging Matters
30 mL Type I borosilicate glass vials protect the solution and support repeated withdrawals.
Verification Matters
Independently tested by a third-party ISO/IEC 17025-aligned lab, with a Certificate of Analysis per lot.
Consistency Matters
Neutral, verified pH and composition so every draw performs the same.
What Consistent, Verified Materials Build Over Time
Batch-tested bacteriostatic water supports a cleaner, more reproducible reconstitution workflow — from first draw through long-term supply.

Research use only.

Everything you need to know
What is bacteriostatic water used for?
It is used in laboratory and research settings to reconstitute and dilute materials. The 0.9% benzyl alcohol limits microbial growth, so a vial can be accessed more than once during a research workflow.
How is it different from plain or bulk water?
Plain water has no bacteriostatic agent and is meant for a single withdrawal once opened. Our vials contain 0.9% benzyl alcohol, come sealed in Type I borosilicate glass, and every lot has a Certificate of Analysis.
How should the vials be stored?
Keep vials sealed until use and store them at room temperature, away from direct sunlight and extreme temperatures. Check that the flip-off cap and seal are intact before opening.
Can this product be used on people or animals?
No. It is sold strictly for laboratory research use. It is not for human or veterinary use, and not for therapeutic or diagnostic purposes.
How long does shipping take?
Orders are processed and shipped within 1–2 business days. Delivery options and estimated arrival dates are shown at checkout.
Do you ship internationally?
Yes, to the countries listed at checkout. Rates, delivery times and any duties depend on the destination and are shown before you pay.
Can I return my order?
Yes. Eligible orders are covered by our 90-day money-back guarantee. See the refund policy for details before sending anything back.
Can I manage or cancel a subscription?
Yes. Skip a delivery, change the date, quantity or pack, pause or cancel any time from your account.
