Sterile Water for Reconstitution
Preservative-free sterile water for single-use peptide reconstitution
Supplied for laboratory research use only. Not for human or veterinary use, and not intended to diagnose, treat, cure or prevent any disease.
Overview
Sterile Water for Reconstitution is purified water that has been sterilized and packaged without any added preservative or buffer. It is the simplest diluent available for dissolving lyophilized peptides and is chosen when a research protocol calls for a single-use preparation, when a compound is known to be sensitive to benzyl alcohol, or when a downstream assay could be affected by the presence of a preservative.

Questions about Sterile Water for Reconstitution
Why would I choose sterile water instead of bacteriostatic water?
Sterile water contains no benzyl alcohol, making it the right choice when a preservative could affect an assay, when a peptide is sensitive to benzyl alcohol, or when a reconstituted solution will be used at once or frozen in aliquots. For multi-draw vials stored in a refrigerator, bacteriostatic water is usually preferred.
What sizes are offered?
Sterile Water for Reconstitution is available in 10 mL and 30 mL vials. Because the product is single-use, many laboratories favor the 10 mL size so less is discarded after each reconstitution; the 30 mL vial suits larger one-time preparations.
Is the water tested and documented?
The vials are manufactured as sterile, non-pyrogenic water and every vial is labeled with a lot number and expiration date. Documentation for the supplied lot is available on request. As a plain reagent, purity by HPLC is not the applicable metric; sterility and endotoxin limits are.
How should sterile water be stored?
Store sealed vials at 20–25 °C, protected from light, and do not freeze the sealed container. Inspect the vial for an intact seal and a clear, particulate-free appearance before each use, and discard any vial that appears cloudy or damaged.
