A plain comparison of two common laboratory water products — bacteriostatic water and sterile water — covering composition and catalogue context only.
Two common laboratory water products
Laboratories often stock bacteriostatic water and sterile water as general aqueous reagents. The notes below describe composition only. My UK Peptides does not publish peptide mixing or reconstitution instructions.
Bacteriostatic water
Typically sterile water containing a preservative (commonly 0.9% benzyl alcohol). It is sold as a laboratory / research supply item. Always follow the product label and your institution’s chemical hygiene rules.
Sterile water
Water that has been sterilised and typically contains no bacteriostatic preservative. It is also a general laboratory supply item; handling rules are set by your institutional SOP.
