Bacteriostatic Water 3ml UK — Best Sterile Research Solution
Bacteriostatic Water 3ml from Astra Labs is a premium sterile water
solution supplied in a sealed glass vial for laboratory research preparation. Each vial
contains 3ml of bacteriostatic water — the standard sterile diluent used in peptide
reconstitution workflows in controlled research environments.
Bacteriostatic water contains 0.9% benzyl alcohol, which inhibits the growth of most
bacteria and fungi. Therefore, it allows a vial to be used multiple times while maintaining
sterility — unlike standard sterile water for injection, which is typically single-use only.
As a result, bacteriostatic water is the preferred diluent for lyophilised peptide
reconstitution in most laboratory settings.

Why Is Bacteriostatic Water Used for Peptide Reconstitution?
Most research peptides are supplied in lyophilised (freeze-dried) powder format for
long-term stability. Therefore, before use in a laboratory setting, they require
reconstitution with a suitable sterile diluent. Bacteriostatic water is the standard choice
for several key reasons:
| Factor | Bacteriostatic Water | Standard Sterile Water |
|---|---|---|
| Benzyl alcohol content | ✅ 0.9% — inhibits bacterial growth | ❌ None |
| Multi-use compatibility | ✅ Multiple withdrawals possible | ❌ Single use only |
| Vial sterility maintenance | ✅ Maintained after puncture | ❌ Compromised after first use |
| Preferred for | ✅ Lyophilised peptide reconstitution | Limited research applications |
Recommended Research Accessories
For a complete laboratory preparation setup, researchers typically use bacteriostatic
water alongside the following Astra Labs accessories:
- ✅ Reconstitution Syringe 5ml 21G — for transferring bacteriostatic water into lyophilised peptide vials
- ✅ Insulin Syringe 0.5ml 29G — for precise measurement after reconstitution
- ✅ Sterile Alcohol Wipes (Pack of 20) — for vial top sterilisation before each withdrawal
Storage Guidance
- Store Bacteriostatic Water 3ml in a cool, dry place at room temperature
- Keep away from direct sunlight and excessive heat
- Once opened, keep refrigerated and use with sterile technique on each withdrawal
- Check vial integrity before use — do not use if seal is compromised

Frequently Asked Questions
What is bacteriostatic water used for?
Bacteriostatic water is a sterile solution containing 0.9% benzyl
alcohol used as a diluent for reconstituting lyophilised research compounds including
peptides. The benzyl alcohol content inhibits bacterial growth, allowing multiple
withdrawals from a single vial while maintaining sterility — unlike standard sterile
water which is single-use only.
How much bacteriostatic water do I need per peptide vial?
The volume of bacteriostatic water used per peptide vial depends on
the specific research protocol and the compound being reconstituted. Researchers should
follow their laboratory’s established procedures and relevant published protocols for
each specific compound.
Why is bacteriostatic water better than sterile water for peptides?
Bacteriostatic water contains 0.9% benzyl alcohol which inhibits
bacterial and fungal growth after the vial is punctured. This makes it suitable for
multi-use withdrawals from a single vial, whereas standard sterile water should only
be used once after the seal is broken. For lyophilised peptide reconstitution in
laboratory research, bacteriostatic water is the standard preferred diluent.
What syringe should I use with bacteriostatic water?
For transferring bacteriostatic water into lyophilised peptide vials,
a reconstitution syringe such as the 5ml 21G is commonly used in laboratory settings.
Astra Labs supplies a 5ml 21G
reconstitution syringe alongside bacteriostatic water.
How quickly is Bacteriostatic Water 3ml dispatched?
Astra Labs dispatches Bacteriostatic Water 3ml within 24–48 hours
from UK stock. Free UK shipping applies on orders over £50 — easily reached when
combined with a peptide compound order. All orders ship in discreet, unmarked
packaging.
What research peptides does Astra Labs supply?
Astra Labs supplies Retatrutide 10mg and 20mg, BPC-157 + TB-500
(Wolverine Stack), CJC-1295 + Ipamorelin, NAD+ 500mg, GHK-Cu 50mg, Semax 10mg,
Selank 10mg and Glow 70mg blend — all for UK laboratory research use only with
Janoshik COA verification and fast domestic dispatch.
