How is Bacteriostatic Water — 10mL Used in Research?
Bacteriostatic water is sterile water for injection USP combined with 0.9% benzyl alcohol as a bacteriostatic preservative, which inhibits microbial growth in the vial once it has been punctured — making it suitable for multi-dose research reconstitution workflows where a single vial is accessed over several weeks. The preservative is effective against a broad range of gram-positive and gram-negative bacteria, yeasts, and molds at the 0.9% concentration specified in USP monographs. Unlike unpreserved sterile water, which must be discarded immediately after piercing the stopper, bacteriostatic water remains usable for up to 28 days when handled with proper aseptic technique.
ReconPartner's bacteriostatic water is manufactured in an FDA-registered, cGMP-compliant facility in the United States. Each lot is filtered to 0.22µm in a class-100 cleanroom, filled into type-I borosilicate glass vials under laminar flow, and terminally tested per USP <71> for sterility and USP <85> for bacterial endotoxins. A Certificate of Analysis accompanies every lot and is linked directly from the product page for researcher reference.
This product is intended solely for laboratory research reconstitution use. It is not intended for human or veterinary use, is not approved by the FDA for therapeutic or diagnostic purposes, and is not to be administered as an injectable to any living organism. Research institutions, academic labs, and individual researchers should handle and store this product in accordance with their own SOPs for aseptic laboratory reagents.
This product is supplied in a lyophilized form and requires reconstitution prior to laboratory handling. For research and laboratory use only. Not for human or veterinary consumption.
Areas of Study
Laboratory Reconstitution
The primary research application — reconstituting lyophilized research-standard reference materials for analytical, in-vitro, or preclinical research workflows. The 0.9% benzyl alcohol preservative allows a multi-dose vial to be used over several weeks without sterility loss.
Analytical Chemistry Workflows
Used as a diluent in HPLC, mass spectrometry, and ELISA sample preparation where sterile, preservative-containing water is required to prevent microbial growth in prepared solutions.
Cell Culture & Tissue Handling
Suitable as a diluent or rinse solution in select cell culture and tissue handling applications where bacteriostatic action is desired. Researchers should confirm compatibility with their specific cell line, as benzyl alcohol can be cytotoxic at higher concentrations.
Long-Storage Stock Solutions
Where a research workflow requires a stock solution to be drawn from repeatedly over days or weeks, the bacteriostatic formulation prevents microbial proliferation between accesses, extending usable lifetime relative to unpreserved sterile water.
