Bacteriostatic water is the reconstitution liquid used to bring lyophilised (freeze-dried) peptide powders back into solution. It is purified water containing 0.9% benzyl alcohol, which acts as a preservative and keeps the vial protected across multiple draws during its usable window. The 3mL vial is the smaller format, enough for a single peptide vial reconstitution with a little to spare.Every peptide vial from Peptides Direct ships with complimentary bacteriostatic water included, so a separate purchase is only needed if you want additional or larger-format supply on hand. The 3mL size covers most single-vial reconstitution needs; the 10mL size is the practical choice for researchers running multiple vials.Store unopened bacteriostatic water at room temperature, away from direct light and heat. Once opened, keep it refrigerated and use it within the manufacturer's recommended window; do not freeze it. When reconstituting a peptide, add the water slowly down the inside wall of the vial — never directly onto the powder — and swirl gently to dissolve rather than shaking.

Prepared with care, sealed under argon, and stored at 2–8°C until dispatch. Reconstitute with bacteriostatic water before use. Full preparation and storage guidance included with your order.
