Bacteriostatic Water 3ml Vial

Cited findings

1. 0.9% benzyl alcohol

   The preservative that makes it bacteriostatic — so a sealed vial can be re-entered through its stopper across its use window.

2. Water-for-injection base

   High-purity water as the solvent, so nothing but the preservative is added to a reconstituted solution.

3. Sized to the vial

   3 ml — enough to reconstitute a standard lyophilised research vial in one preparation.

4. Why not sterile water

   Plain sterile water has no preservative and is single-use; bacteriostatic water is the multi-use choice.

5. Included with peptides

   A 3 ml vial is included with every peptide vial, so reconstitution is covered from the first order.

The multi-use standard for reconstitution: water for injection preserved with 0.9% benzyl alcohol, in a 3 ml vial sized to match.

A 3ml multi-dose vial of bacteriostatic water — sterile water containing 0.9% benzyl alcohol as a bacteriostatic preservative. The benzyl alcohol inhibits the growth of bacteria, allowing the vial to be punctured multiple times over a period of use without compromising sterility, which makes it the standard diluent for reconstituting lyophilised research peptides. The rubber-stoppered vial is designed to be drawn from with a needle and supports repeated, controlled withdrawals. Once opened, store refrigerated and observe a sensible in-use period. Bacteriostatic water is a preparation aid only.

Mechanism, as studied

Benzyl alcohol at 0.9% suppresses bacterial growth without reacting with the peptide it dissolves.

1. STEP 01Water for injection dissolves the lyophilised powder
2. STEP 02Benzyl alcohol keeps the solution bacteriostatic
3. STEP 03The stopper reseals between entries
4. STEP 04Store the reconstituted vial cold and sealed

Draw the required volume with a sterile syringe to reconstitute lyophilised peptides. Swab the stopper before each use. Store refrigerated once opened and observe a sensible in-use period.

Store in a cool, dry place; refrigerate once opened. For reconstitution use. Keep out of reach of children.
