Product Comparison
Most online bacteriostatic water is produced overseas, supplied without lot-level verification, and sold without recourse if it fails specification. Here is what separates our vial from generic alternatives.
Recommended Choice
Manufactured in the United States
Produced in a US facility with a documented, auditable supply chain.
Verified 0.9% Benzyl Alcohol
Pharmacopoeia-grade preservative concentration confirmed on every production lot. No deviation, no substitution.
Type I Borosilicate Glass Vials
Low-extractable, chemically inert glass — the same specification used in pharmaceutical packaging.
Lot-Tested by an Independent Third-Party Lab
Identity, purity, and concentration verified by an accredited third-party lab before release.
Tamper-Evident Crimp Seal
Rubber septum + aluminum crimp seal on every vial. Integrity verifiable on receipt.
Certificate of Analysis on Request
Documentation issued per production lot — available before purchase or with your shipment.
30-Day Money-Back Purity Guarantee
If any vial fails published specification, full refund. No restocking fee, no return shipping cost.
Typical Generic Supplier
Often Sourced Overseas
Many online sellers source from unidentified overseas manufacturers with no auditable supply chain.
Unverified Preservative Concentration
Generic vials rarely publish a tested benzyl alcohol concentration. Buyers receive no lot-level verification.
Mixed Glass / Plastic Containers
Generic supply may use soda-lime glass or plastic. Inert-glass guarantees are not standard.
Self-Reported Testing (If Any)
Most low-cost vendors rely on supplier-issued certificates rather than independent third-party verification.
Standard Cap, No Seal Verification
Standard screw caps with no tamper-evident seal — integrity cannot be confirmed on arrival.
Rarely Provides Documentation
Most online sellers do not issue CoAs. When asked, they substitute a generic spec sheet.
All Sales Final
Generic suppliers commonly enforce no-return policies. Failed product is the buyer's loss.
Manufactured in the USA
Every BAC Water Depot vial originates at a facility within the continental United States. The supply chain — from sterile water input through final crimp seal — is documented and auditable end-to-end.
For research buyers this means reproducibility: the vial you order this quarter matches the vial you ordered last quarter. Same facility, same process, same specification.

The best research-grade bacteriostatic water is manufactured in the United States under documented quality standards, contains a verified 0.9% benzyl alcohol preservative concentration, ships in Type I borosilicate glass vials with tamper-evident crimp seals, and is accompanied by a Certificate of Analysis (CoA) issued per production lot. BAC Water Depot meets all four criteria and verifies every lot through an independent accredited testing laboratory.
Yes — BAC Water Depot's bacteriostatic water is manufactured entirely within the United States at a registered facility. Most low-cost online sellers source bacteriostatic water from unidentified overseas suppliers with no auditable supply chain.
Single 10 mL vials are $9.99; a 10-vial pack is $74.99 ($7.49 per vial), a 25-vial pack $174.99 ($6.99 per vial), and volume pricing drops to $6.74 per vial from 150 vials and $6.49 from 500. Larger packs (50 to 300 vials) are listed on the product page, and orders of 1,000+ vials get a custom quote. Free shipping on domestic US orders over $250.00.
Bacteriostatic water is used to reconstitute lyophilized (freeze-dried) compounds in research and laboratory settings. The 0.9% benzyl alcohol preservative inhibits bacterial growth in the reconstituted solution, allowing multiple draws from the same vial over an extended research period. BAC Water Depot's vials are supplied for research and laboratory use only — not for human or veterinary use.
Sterile water for injection (SWFI) contains no preservatives and is intended for single use — once opened, the remaining volume must be discarded. Bacteriostatic water contains 0.9% benzyl alcohol as a bacteriostatic preservative, which permits multiple draws from the same vial over time. For laboratory reconstitution of lyophilized research compounds, bacteriostatic water is generally preferred when multiple doses or draws are needed from a single vial.
Bacteriostatic water is purified water containing 0.9% benzyl alcohol as a bacteriostatic preservative — used primarily to reconstitute lyophilized research compounds. Saline (0.9% sodium chloride) contains dissolved salt to match physiological osmolarity and is used for dilution, irrigation, or as a diluent for certain solutions. The two are not interchangeable: bacteriostatic water has no electrolytes; saline has no preservative.
Benzyl alcohol is an aromatic alcohol used as a bacteriostatic preservative — it inhibits the growth of common bacteria within sealed, multi-draw vials. The 0.9% concentration used in pharmacopoeia-grade bacteriostatic water is the standard specification verified for compatibility with most reconstitution applications. BAC Water Depot lots are tested to confirm 0.9% concentration on every production run.
Sealed BAC Water Depot vials store indefinitely per manufacturer specification when kept upright in a cool, dry location away from direct sunlight. Once a vial has been pierced and drawn from, standard laboratory practice typically allows continued use for up to 28 days, after which the vial should be discarded. Follow your facility's standard operating procedures for opened-vial storage.
Store unopened BAC Water Depot vials upright at controlled room temperature (15–30 °C / 59–86 °F) in a dry environment away from direct sunlight. No refrigeration is required for sealed vials. Once a vial is opened, refrigeration (2–8 °C) is recommended per typical laboratory SOPs to extend usable life within the 28-day post-puncture window.
Yes. Every production lot is independently verified by an accredited third-party laboratory for identity, purity, and concentration before release. A Certificate of Analysis (CoA) is issued per production lot and is available on request — before purchase or with the shipment. The published purity specification is >98%, backed by our 30-day money-back guarantee.
Each BAC Water Depot Certificate of Analysis documents the lot number, manufacturing date, identity verification, purity assay result, benzyl alcohol concentration confirmation (target 0.9%), appearance/clarity inspection, pH, and the name of the independent testing laboratory that verified the lot. CoAs are issued per production lot and tied directly to the vial lot you receive.
BAC Water Depot supplies 10 mL bacteriostatic water vials. The 10 mL size is the standard laboratory configuration for multi-draw reconstitution applications. Larger pack configurations (10-vial, 25-vial, bulk 25–500) are available — but the vial size itself is consistently 10 mL across all SKUs.
All BAC Water Depot bacteriostatic water vials are Type I borosilicate glass — the same low-extractable, chemically inert glass specification used in pharmaceutical packaging. Type I glass is preferred over plastic and soda-lime glass for research-grade reagent containment because it minimizes leachables and interactions with the contents.
USA manufacturing in a registered facility provides an auditable supply chain, documented standard operating procedures, and direct accountability for every production lot. Overseas sources commonly have unverified manufacturing, inconsistent lot-to-lot specifications, and limited recourse if a vial fails specification. BAC Water Depot maintains a documented end-to-end domestic supply chain from sterile water input through final crimp seal.
BAC Water Depot's bacteriostatic water is produced to specifications referencing USP standards for sterile water and benzyl alcohol preservative content. The vials are intended for research and laboratory use only. We do not market the product as a finished pharmaceutical, and we do not provide clinical, veterinary, or human-use guidance.
