Two monographs, one difference, and why the pack contains the preserved one

Published 26 October 2026 · REVIVE LAB UAE Research Desk · 5 min read
Sterile Water for Injection is water alone, sterile and endotoxin-limited, in single-use containers; once opened it has no defence against contamination and is discarded. Bacteriostatic Water for Injection is the same water with an antimicrobial agent, which is what permits a container to be entered more than once. A lyophilised peptide vial is dissolved and then drawn from repeatedly over time, so the preserved water is the one supplied with it.

What they share

Both start from water for injection: purified by distillation or an equivalent process, with the same limits on endotoxin, conductivity and total organic carbon. Both are sterilised and filled into sterile containers. Chemically, apart from the preservative, they are the same liquid.

Neither contains salt; neither is isotonic; neither is buffered.

Where they differ

The preservative. Sterile water in a single-use vial relies on being used once and discarded. Bacteriostatic water relies on the agent to inhibit any organism introduced at a later entry. That difference determines the container size limit, the labelling, and the newborn warning, which applies only to the preserved product.

The preservative also introduces a chemical that sterile water lacks — relevant to assays, as other pages here describe.

Why the pack holds the preserved one

A dissolved peptide vial is a multiple-entry container by nature. Supplying it with single-use water would leave the solution unprotected from the first draw onward. This is a statement about the two products; it is not a procedure.

Bacteriostatic water is supplied by REVIVE LAB UAE as a diluent for lyophilised research peptides, for laboratory research use only. It is not for human or veterinary use, and no dosing, administration or protocol guidance is provided.
