Buy Bacteriostatic Water Australia | Peptide Reconstitution

Peptides Collective stocks pharmaceutical-grade bacteriostatic water for researchers needing a reliable reconstitution solution for lyophilised peptides. Dispatched from Perth, WA with fast Australia-wide shipping.

What Is Bacteriostatic Water?

Bacteriostatic water is sterile water containing 0.9% benzyl alcohol, which inhibits bacterial growth. Unlike standard sterile water, it allows a vial to be accessed multiple times without contamination risk, making it the preferred reconstitution vehicle for research peptides.

Why Use Bacteriostatic Water for Peptide Reconstitution?

• Multiple-use safe - benzyl alcohol prevents bacterial contamination across multiple withdrawals
• Peptide stability - preserves reconstituted peptide integrity longer than plain sterile water
• Research standard - the recognised vehicle for reconstituting research-grade lyophilised peptides
• Compatible - suitable for all peptides stocked by Peptides Collective

How to Use Bacteriostatic Water

See our detailed How to Reconstitute Peptides guide for step-by-step instructions. In brief: draw the desired volume into an insulin syringe, inject slowly into the lyophilised peptide vial along the vial wall, swirl gently until dissolved. Never shake.

Frequently Asked Questions

Can I use sterile water instead?

Sterile water can be used but only supports single-use withdrawal. For research requiring multiple doses from one vial, bacteriostatic water is strongly preferred.

How should I store bacteriostatic water?

Store at room temperature away from direct sunlight. Once opened, use within 28 days.

How much do I need per vial?

Typically 1-2 mL per peptide vial, depending on your target concentration. Our reconstitution guide has full guidance.

Is bacteriostatic water available in Australia?

Yes. Peptides Collective stocks bacteriostatic water and ships Australia-wide from Perth, WA.
