Bacteriostatic Reconstitution Solution — 10 mL Triple-Sealed Glass Vials, Lab-Grade

Most diluent gets treated like an afterthought. Researchers obsess over the peptide and then store it with whatever water shipped in a flimsy plastic bottle. That's backwards. Your bacteriostatic reconstitution solution touches every sample you prepare — so the vial it lives in, and how clean that solution actually is, matters just as much as what you're dissolving.

Bacteriostatic reconstitution solution (also called bacteriostatic water or BAC water) is an aqueous diluent containing 0.9% benzyl alcohol (BZA), used to dissolve lyophilized (freeze-dried) research peptides and proteins in a controlled laboratory setting. This formulation is packaged in triple-sealed 10 mL glass vials: clear glass so you can actually inspect what you're working with, sealed three ways so contamination doesn't get a vote. Every batch is independently third-party tested — view the Certificate of Analysis (COA) (pg. 2 · pg. 3).

Why researchers choose this bacteriostatic reconstitution solution

Triple-Sealed Vial Design

• Triple-sealed protection. Every 10 mL vial uses three layers of defense — high-clarity glass, a self-sealing rubber stopper, and an aluminum crimp cap — so the solution stays free of contamination and leaks from the day it ships to the day you draw from it.
• Real glass, not plastic. High-clarity laboratory glass lets you visually verify clarity and check for particulates — and it won't leach the way cheap plastic can.
• Leak-proof & contamination-resistant. The crimp-sealed stopper is designed for clean access and secure storage between uses.

Formula & Purity

• Ultra-clean aqueous formula. Made with 99.1% ultra-pure water and 0.9% benzyl alcohol (BZA) — the industry-standard bacteriostatic agent that inhibits microbial growth and extends the usable life of reconstituted research compounds.
• Lab-grade purity (>99%). Formulated to laboratory chemical standards, not consumer grade. Consistent composition across every vial.

Third-Party Certificate of Analysis

• Independently tested. Every batch is verified by a third-party lab. Full COA available: pg. 1 · pg. 2 · pg. 3.
• Transparent sourcing. No guesswork about what's in the vial. Purity, composition, and test results are documented and accessible.

Bacteriostatic Water vs. Sterile Water: Which Should You Use?

The right diluent depends on your research workflow. Bacteriostatic water (this product) contains 0.9% benzyl alcohol (BZA), which inhibits bacterial growth and allows a single vial to be accessed multiple times — making it the preferred choice for most peptide reconstitution protocols in research lab settings. Sterile water contains no preservative and is intended for single-use reconstitution only, since each needle puncture introduces contamination risk. If your protocol requires repeated draws from the same vial, bacteriostatic reconstitution solution is the appropriate choice.

Frequently Asked Questions

What is bacteriostatic reconstitution solution used for?

It is used to dissolve lyophilized (freeze-dried) research peptides, proteins, and other compounds into a liquid form suitable for use in laboratory and in vitro research settings. The benzyl alcohol content inhibits microbial contamination, which is critical when a vial will be accessed multiple times.

What is the difference between bacteriostatic water and sterile water for reconstitution?

Bacteriostatic water contains 0.9% benzyl alcohol (BZA) as a preservative, allowing multi-use access to a single vial while reducing contamination risk. Sterile water contains no preservative and should only be used for single-draw reconstitution. For most peptide research protocols requiring repeated access, bacteriostatic reconstitution solution is the standard choice.

How long does a reconstituted peptide stay stable with bacteriostatic water?

Stability varies by compound, storage temperature, and other factors specific to each research protocol. In general, reconstitution with bacteriostatic water and storage at 2–8°C (refrigerated) is associated with longer compound stability than sterile water, due to the benzyl alcohol preservative. Always consult the relevant literature for your specific compound.

Why use glass vials instead of plastic for reconstitution solution?

High-clarity laboratory glass allows visual inspection for particulates or discoloration, does not leach plasticizers or other contaminants into the solution the way some plastics can, and provides a more inert storage environment. The triple-sealed design (glass + rubber stopper + aluminum crimp cap) also provides superior contamination resistance compared to most plastic containers.

Is this product suitable for human use?

No. This product is intended exclusively for laboratory and scientific research. It is not a drug or medical device and is not intended to diagnose, treat, cure, or prevent any disease, nor for use in humans or animals.

Is this the same as BAC water?

Yes. "BAC water," "bacteriostatic water," and "bacteriostatic reconstitution solution" all refer to the same type of product: an aqueous solution containing a low concentration of benzyl alcohol (typically 0.9%) used as a diluent for research compounds. This product contains 99.1% ultra-pure water and 0.9% benzyl alcohol.
