What is Bacteriostatic Water, and what is it used for?
Bacteriostatic Water is also listed and searched as BAC Water, bacteriostatic water with benzyl alcohol, bacteriostatic water 0.9% benzyl alcohol, bacteriostatic water for injection. They all mean the same compound. A name is not a test, which is why the lot record further down counts for more than the wording on a label.
Chemically: molecular formula C7H8O, average mass 108.14 g/mol (PubChem CID 244). The diluent itself is water. Bacteriostatic water is water containing 0.9% benzyl alcohol as a preservative, so a certificate reports the preparation - water, preservative concentration, sterility and pH - and not a single molecular mass.
Bacteriostatic water: sterile water with benzyl alcohol added to hold back bacterial growth. Not a peptide and not an active compound.
The benzyl alcohol stops bacteria multiplying, which is what separates bacteriostatic water from plain sterile water and is why a sealed multi-use container can be entered more than once under laboratory conditions.
A laboratory diluent rather than a subject of research. What matters here is that it is a solvent, and what a solvent is made of affects the stability of whatever gets dissolved in it.
This record covers the diluent as laboratory material only. Nothing here describes preparing, combining or administering any substance, and a diluent being in the catalog implies no such use.
Bacteriostatic Water for sale: 3ml and 10ml vials, price per mL
Bacteriostatic Water is sold in 2 sizes here, 3ml and 10ml, from $12.00 a vial. Bacteriostatic Water cost and Bacteriostatic Water price per mL by size are in the table, at each volume tier and on subscription; the per-mL figure under each price is the one that compares across sizes.
Volume and subscription pricing by size

The 10ml vial works out 63% cheaper per mL than the 3ml. Volume tiers are per size and do not combine across sizes (see bulk pricing). Subscribe & Save takes 6% every month, 4% every 2 months or 2% every 3 months off from shipment 2, two shipments minimum, and stacks on the volume tier: the lowest this record ever bills is $1.20 per mL, twenty 10ml vials on a monthly subscription from shipment 2 onward.
Nothing is added at checkout except the USPS shipping you choose; dispatch and delivery are the same on every order. The cost-per-milligram tool ranks the whole catalog by price per mL. The certificate walked through field by field: Where to Buy Bacteriostatic Water: What to Check First.

Where to get Bacteriostatic Water, and how to buy Bacteriostatic Water online
Bacteriostatic Water for sale, or Bacteriostatic Water peptide for sale, means this page: one record, 2 sizes. You can buy Bacteriostatic Water online here with guest checkout, and purchase Bacteriostatic Water or order Bacteriostatic Water in any size below; verified in-stock orders placed before 12 PM Pacific are dispatched the same day. If the question is where to get Bacteriostatic Water or how to get Bacteriostatic Water, the answer for a US laboratory is a supplier who publishes the certificate before you pay, which is the first of the five checks that follow. A Bacteriostatic Water supplier, vendor or source worth using will show you the lot number and where its certificate can be verified.
Before ordering Bacteriostatic Water from anyone, us included, run the 5 checks on verifying a certificate; the first is that the report resolves on the laboratory's own site, and a seller who cannot pass them is asking for the trust a certificate exists to replace.

The Bacteriostatic Water record: lot, what is in the vial, and what the paperwork shows
A diluent is not tested for identity and purity the way a peptide is, so this record does not pretend to a certificate it does not have. What it carries is the lot, the composition, and the fill volume checked per lot. The benzyl alcohol stops bacteria multiplying, which is what separates bacteriostatic water from plain sterile water and is why a sealed multi-use container can be entered more than once under laboratory conditions.
Do you need a prescription for Bacteriostatic Water? What this vial is
Bacteriostatic Water for Injection, USP, is a pharmaceutical product made by drug manufacturers and dispensed under their rules. The vial on this page is a laboratory diluent, sterile water with benzyl alcohol as the bacteriostat, sold for bench work: no prescription is involved because it is not sold for use in anyone, and it is not a medicine. LabFirst is not a pharmacy or a compounding facility. Which product a laboratory needs depends on the work, and this record does not pretend to be the other one.
How to store Bacteriostatic Water: refrigeration and shelf life
Keep the sealed vial cold and out of the light and it stays as it left the lab. Once it is mixed into a solution, how long it holds up depends on the compound, what it was mixed with, how strong the solution is and how cold it is kept — too many variables for anyone to print one shelf life on a label. So laboratories write the date on whatever they prepare and keep their own record of it.
The benzyl alcohol stops bacteria multiplying, which is what separates bacteriostatic water from plain sterile water and is why a sealed multi-use container can be entered more than once under laboratory conditions. Once a multi-use vial has been entered, the laboratory dates it and keeps its own record; there is no single shelf life that survives every bench.
