BAC water overview
Hospira bacteriostatic water is sterile water containing benzyl alcohol as a preservative, supplied in a 30 mL multi-dose vial. In peptide research it is commonly used as a diluent to reconstitute lyophilized vials. This item is sold as an add-on to a peptide order.

Quality documentation
Each batch is tracked by the lot reference shown in the specifications table, and the certificate status tells you whether a certificate of analysis is on file for that lot. A peptide certificate of analysis typically reports purity by HPLC, which measures how much of the material is the main component, and identity by mass spectrometry, which confirms that the main component has the expected molecular mass. To request the certificate for your lot, contact our team with the product name and lot reference. Our research guides explain how to read each section of a COA.
Certificate on file means a certificate is held for the lot currently in stock. COA pending means documentation for the current lot is still being finalised; you can ask us to confirm its status before you order.
Working with BAC water
Bacteriostatic water is used as a diluent when reconstituting lyophilized peptides. Wipe the stopper with alcohol before each withdrawal, use a fresh sterile needle or pipette tip each time, and label the vial with the date it was first opened. Record the diluent lot alongside the peptide lot in your notes so that each prepared solution can be traced.
How this format compares
Bacteriostatic water contains benzyl alcohol as a preservative, which allows a multi-dose vial to be entered more than once. Sterile water without a preservative is intended for single use once opened. Which diluent suits a given peptide depends on its solubility and the protocol, so check the guidance for the compound you are working with.
Handling and storage
Store unopened vials at controlled room temperature. Once the stopper has been punctured, follow the in-use guidance on the label. Benzyl alcohol acts as a preservative in multi-dose vials, but it does not make a vial safe to use indefinitely, so discard any vial that looks cloudy or discoloured and label each vial with the date it was first opened.
