Bacteriostatic Water · UK Warehouse · 24hr Tracked
Buy Bacteriostatic Water in the UK — the standard peptide reconstitution solvent.
Bacteriostatic water is the sterile diluent used to reconstitute lyophilised research peptides. Momentum Peptides supplies it from a UK warehouse — sterile water with 0.9% benzyl alcohol, dispatched same-day with 24-hour tracked delivery.
Available in sealed 3ml and 10ml vials.
What Bacteriostatic Water Is
Bacteriostatic water is sterile water containing 0.9% benzyl alcohol — a preservative that inhibits bacterial growth and allows a single sealed vial to be drawn from multiple times during a research workflow.
Lyophilised (freeze-dried) research peptides arrive as a solid powder and must be reconstituted into solution before use. Bacteriostatic water is the standard diluent for this. The 0.9% benzyl alcohol is what separates it from plain sterile water: because it suppresses microbial growth, a sealed vial remains usable across a multi-day research protocol rather than being single-use once opened.
This is why bacteriostatic water is the diluent referenced throughout published peptide reconstitution literature, and the default solvent stocked alongside the peptides themselves. Every peptide order from Momentum includes bacteriostatic water and needles as standard.
Bacteriostatic vs Sterile vs Saline Water
Three water types appear in reconstitution research. The differences come down to preservative and reuse.
How to Reconstitute Peptides with Bacteriostatic Water
1. Draw the diluent. Use the peptide reconstitution calculator to work out the exact volume of bacteriostatic water for your target concentration, then draw it into a sterile syringe.
2. Add it slowly. Inject the water down the inside wall of the peptide vial — not directly onto the lyophilised powder — to avoid disturbing the peptide.
3. Dissolve gently. Swirl gently until fully dissolved; do not shake. The solution should appear clear. Store reconstituted peptide solutions refrigerated at 2–8°C.
Why Source Bacteriostatic Water in the UK
Ordering bacteriostatic water from overseas introduces customs delays on the one consumable you need before any peptide research can begin. Momentum Peptides holds stock in a UK warehouse and dispatches same-day — order it alongside your peptides and receive everything together, in days rather than weeks.
Supplied in sealed sterile vials, ready for controlled laboratory use.
Preservative-grade formulation supporting multi-use access to a single sealed vial.
Stock held in a UK warehouse, dispatched same or next working day with 24hr tracked delivery.
Add it to any peptide order and receive everything in a single tracked UK shipment.
Delivery Across the UK
Momentum Peptides dispatches bacteriostatic water from a UK warehouse via tracked courier, with same-day dispatch on orders placed before the daily cut-off.
Frequently Asked Questions
Do you deliver bacteriostatic water across the UK?
Yes. Stock is held in a UK warehouse and dispatched same or next working day with 24-hour tracked delivery across the UK.
What is bacteriostatic water used for?
It is the sterile solvent used to reconstitute lyophilised research peptides into liquid form. The 0.9% benzyl alcohol allows a sealed vial to be drawn from multiple times.
What is the difference between bacteriostatic water and sterile water?
Bacteriostatic water contains 0.9% benzyl alcohol as a preservative, allowing repeated access to a sealed vial. Plain sterile water has no preservative and is single-use once opened.
What vial sizes are available?
Bacteriostatic water is supplied in sealed 3ml and 10ml vials, subject to stock availability.
How should bacteriostatic water be stored?
Store at room temperature, away from direct light. It does not require refrigeration prior to opening.
Is bacteriostatic water for human use?
No. It is supplied strictly for laboratory research use only and is not intended for human or veterinary use, consumption or injection.
