Sterile water versus bacteriostatic water, which do I need?

Sterile water is preservative-free and single-use. Bacteriostatic water contains a 0.9 percent benzyl alcohol preservative and suits most peptides and multi-dose use, where a vial is drawn from repeatedly.

Can sterile water be stored after opening?

No. Because it contains no preservative, a single-use ampoule is used once and not retained after opening. Choose bacteriostatic water for multi-dose work.

How much sterile water do I add per vial?

The exact reconstitution volume is set by the research protocol. The 30ml format covers single-application reconstitution across multiple peptide vials.

Which water do I need?

Sterile water (this product) is preservative-free and single-use. Choose it for compounds incompatible with benzyl alcohol, or where a protocol calls for no preservative.

Bacteriostatic water contains a benzyl alcohol preservative and suits most peptides and multi-dose use, where a vial is drawn from repeatedly over days or weeks. See bacteriostatic water →
