Buy Bacteriostatic Water UK | Premium 10ml & 30ml Sterile Vials
Welcome to the UK’s most trusted destination to buy bacteriostatic water. Whether you are conducting scientific research, running clinical assays, or reconstituting delicate peptides in a laboratory setting, the quality of your diluent (the dissolving agent) dictates the accuracy and safety of your results.
Our bacteriostatic water is processed to the highest pharmaceutical standards. Unlike standard sterile water which must be discarded immediately after a single use, our bacteriostatic water is specially formulated for multi-dose applications, giving you maximum flexibility without compromising sterility.
What is Bacteriostatic Water?
Bacteriostatic water (frequently shortened to BAC Water) is highly purified, sterile water containing 0.9% benzyl alcohol ($C_7H_8O$).
The addition of benzyl alcohol acts as an incredibly effective preservative. It stops the growth of potentially harmful bacteria and microorganisms without altering the chemical structure of the compounds you are dissolving. This unique chemical composition means you can repeatedly access the same vial using sterile procedures for up to 28 days once opened.
The Key Benefits of Our BAC Water
When you choose to buy bacteriostatic water from our UK store, you are investing in unmatched product integrity. Our clients choose us for several distinct reasons:
-
Extended Shelf Life: Standard sterile water must be thrown away immediately after opening to avoid contamination. Our formulation remains sterile for up to 4 weeks after the first vial puncture.
-
Strict pH Balance: We carefully monitor and maintain a neutral pH level (typically between 4.5 and 7.0) to prevent any degradation of your fragile compounds during reconstitution.
-
Unrivalled Versatility: This product is the gold standard diluent for synthetic peptides, laboratory reagents, and clinical research compounds.
-
Multi-Dose Efficiency: Save time and minimize laboratory waste by utilizing our robust, self-sealing rubber stopper vials designed for multiple draws.
Purity and Quality Assurance
We do not cut corners. Because we serve the highly demanding UK research and medical community, every single batch of bacteriostatic water goes through a rigorous purification process:
-
Reverse Osmosis & Distillation: Raw water is stripped of organic compounds, minerals, heavy metals, and dissolved solids.
-
Sterilisation: The purified water is micro-filtered to eliminate any potential microscopic pathogens, ensuring a completely pyrogen-free base.
-
Preservative Integration: Exactly 0.9% medical-grade benzyl alcohol is introduced under sterile conditions.
-
Vacuum Sealing: The final solution is bottled in pharmaceutical-grade glass vials and sealed with a secure, flip-off aluminium cap to guarantee a tamper-proof barrier.
Essential Usage Information
To maintain the absolute sterility of your bacteriostatic water, always follow these core protocols:
-
Sanitation First: Wipe the rubber stopper of your vial with a 70% isopropyl alcohol prep pad before inserting any needle.
-
Prevent Vacuum Buildup: Draw an equivalent volume of air into your syringe before inserting it into the vial, then inject the air to equalize vial pressure.
-
Gentle Reconstitution: When mixing with a lyophilised (freeze-dried) compound, slowly dribble the water down the inside glass wall of the compound vial rather than spraying it directly onto the powder. This protects delicate molecular chains.
Storage & Handling Guidelines
Proper storage ensures your BAC water retains its bacteriostatic properties for the entirety of its shelf life:
| Condition | Recommended Protocol |
| Unopened Vials | Store at controlled room temperature ($15^\circ\text{C}$ to $30^\circ\text{C}$) away from direct sunlight. Do not freeze. |
| Opened Vials | Keep in a cool environment (refrigeration at $2^\circ\text{C}$ to $8^\circ\text{C}$ is optimal). Mark the date of first puncture clearly on the label. |
| Discard Window | Safely discard any remaining solution exactly 28 days after first opening, regardless of how much liquid is left. |
Certified Lab Testing
Safety and compliance sit at the heart of our mission. Every batch of our bacteriostatic water undergoes independent, third-party laboratory testing to verify:
-
Absolute sterility (free from viable microorganisms).
-
Endotoxin levels well below the permitted pharmacopeia limits.
-
Precise 0.9% benzyl alcohol concentration.
Batch numbers and expiry dates are clearly stamped on every vial, allowing for total transparency and traceability.

Frequently Asked Questions (FAQs)
Is it legal to buy Bacteriostatic Water in the UK?
Yes. It is completely legal to buy and possess bacteriostatic water in the UK for laboratory, research, and analytical purposes.
Can I use bacteriostatic water for intravenous use without a solute?
No. Pure bacteriostatic water should never be injected directly into a vein without a solute, as it is hypotonic and can cause hemolysis (the breakdown of red blood cells). It must always be combined with an appropriate solute to reach an isotonic state before administration.
