Description
What Bacteriostatic Water Is Used For
In research settings, lyophilized (freeze-dried) peptides must be reconstituted into solution before use. Bacteriostatic water is the common reconstitution solvent because the benzyl alcohol preservative supports multiple sterile withdrawals from one vial across a multi-week protocol — unlike single-use sterile water, which has no preservative.
Bacteriostatic vs. Sterile Water vs. Saline
- Bacteriostatic water: sterile water + 0.9% benzyl alcohol; multi-dose; preserved for repeated withdrawals (commonly cited as up to 28 days once punctured, refrigerated).
- Sterile water: no preservative; single-use; discard after one withdrawal.
- Bacteriostatic saline (0.9% NaCl + benzyl alcohol): a different diluent used in some protocols; not interchangeable for all compounds.
See the reconstitution math guide for concentration calculations.

Research use only. Not for human or veterinary use. Not a medical product.
Preparation and storage
Research-only handling information. Bacteriostatic water is supplied for in vitro laboratory research (reconstitution of research compounds). It is not for human consumption, injection, veterinary, or medical use.
Using Bacteriostatic Water for Reconstitution
- Wipe the vial stopper before each withdrawal.
- Draw the required volume with a sterile syringe; add against the inside wall of the peptide vial, not directly onto the lyophilized cake.
- The volume added determines the final peptide concentration — see the reconstitution math guide.
Storage & Handling
- Unopened: store at controlled room temperature (20–25 °C / 68–77 °F), protected from light.
- After first puncture: refrigerate at 2–8 °C.
- Multi-dose window: the benzyl alcohol preservative supports repeated withdrawals for a limited period (commonly cited as up to 28 days after first puncture); discard after the protocol's defined window.
- Do not use if the solution is cloudy, discolored, or the seal is compromised.

Frequently asked questions
Frequently asked questions about Bacteriostatic Water 10ml. Questions on this page cover use, storage, and ordering. Bacteriostatic water is sold for laboratory, research, or analytical purposes only — not for human consumption, injection, veterinary, or medical use.
What is bacteriostatic water used for?
It is the standard diluent for reconstituting lyophilized research peptides. The 0.9% benzyl alcohol preservative allows repeated sterile withdrawals from one multi-dose vial.
What is the difference between bacteriostatic and sterile water?
Bacteriostatic water contains 0.9% benzyl alcohol as a preservative and supports repeated withdrawals from a multi-dose vial. Sterile water has no preservative and is single-use.
How much bacteriostatic water do I use per vial?
It depends on the target concentration — the volume added sets the final concentration of the reconstituted compound. See the reconstitution math guide.
How long does bacteriostatic water last after opening?
The benzyl alcohol preservative supports repeated withdrawals for a limited period, commonly cited as up to 28 days after first puncture when refrigerated. Discard after the protocol's defined window.
How should bacteriostatic water be stored?
Unopened at controlled room temperature, protected from light; refrigerate at 2–8 °C after first puncture. Do not use if cloudy, discolored, or if the seal is compromised.
Is this product for human use?
No. It is supplied for laboratory, research, or analytical purposes only — not for human consumption, injection, veterinary, or medical use.
What is included?
One 10ml sterile multi-dose vial of bacteriostatic water (0.9% benzyl alcohol), batch-tested with a COA available on request.
