Bacteriostatic Water
0.9% Benzyl Alcohol · For Reconstitution
Sterile water with 0.9% benzyl alcohol for laboratory reconstitution of lyophilized research materials.
What is Bacteriostatic Water?
Sterile water containing 0.9% benzyl alcohol as a bacteriostatic preservative, used to reconstitute lyophilized research materials. The preservative allows a sealed vial to be accessed more than once under laboratory conditions.

Certificate in queue
This lot is with our third-party laboratory. Its certificate will be published here and on the COA lookup as soon as testing completes.
How every batch is tested$12
Dispatched within 24 hours, Monday to Friday, in discreet, unmarked packaging. Free shipping over $200 — $188 away.
COA match guarantee — if the vial you receive does not match the certificate published for its batch, we replace or refund it. Unopened vials in original packaging can be returned within 14 days of delivery.
A batch that misses specification is not listed and is not shipped. We publish every result we commission, including the ones that send a batch back.
Chromatogram and mass-spectrometry data for this compound are available on request.

Four checks stand between synthesis and a listing.
Every lot in this catalog clears the same sequence. The dates below belong to batch GLP3-10-2026-01 — an example of a released lot. Certificates for other products are added as testing completes.

Synthesis and fill
Lyophilized to specification and sealed under controlled conditions, one lot at a time.

Chromatographic purity
RP-HPLC with UV detection at 220 nm — the peptide-bond absorbance, so every residue in the sequence contributes to the signal. Release specification ≥ 98.0%.
Result 99.4%

Identity confirmation
LC-MS (ESI) measures the molecular mass of the eluting species against the theoretical mass of the intended sequence. A lot can be pure and still be the wrong peptide; running both methods closes that gap.

Release
Purity, identity, appearance, peptide content, water, acetate and endotoxins all within specification. Released for sale.

When a batch does not clear
It is not listed and it is not shipped. We publish every result we commission, including the ones that send a batch back. A batch earns a product page only after identity and purity have both passed.
Analytes on the record
- HPLC Purity≥ 98.0%
- Mass SpectrometryMatches Structure
Chromatographic purity and peptide content answer different questions. Purity is the share of peptide-related material that is the target sequence. Peptide content is how much of the vial's mass is peptide at all, the remainder being acetate counterion and residual water — a normal lyophilized acetate salt, not a discrepancy.
Analysis is performed by JanoShield Analytical, an independent laboratory with no commercial interest in the result.

Common questions
What is Bacteriostatic Water?
Sterile water containing 0.9% benzyl alcohol as a bacteriostatic preservative, used to reconstitute lyophilized research materials. The preservative allows a sealed vial to be accessed more than once under laboratory conditions.
How is Bacteriostatic Water purity verified?
Every lot is assayed by third-party hplc and mass spectrometry, per batch: RP-HPLC at 220 nm establishes chromatographic purity against a 99% release specification, and LC-MS confirms molecular identity against the reference mass. The batch currently shipping is RV-BAC-2630, and its full certificate — including methods, specifications, measured results, and the testing laboratory — is published at https://rovapeptides.com/coas/RV-BAC-2630.
How should Bacteriostatic Water be stored and handled?
Sterile solution, sealed multi-use vial. Store lyophilized at -20 °C, protected from light and moisture. Refrigerate after reconstitution. Wipe the septum before each withdrawal and store the sealed vial at controlled room temperature, away from light.
What strengths of Bacteriostatic Water are available?
Bacteriostatic Water is supplied in 30 mL. Each presentation is filled from a tested lot and ships with its own batch number, so the certificate you retrieve always corresponds to the vial in your hand.
Is Bacteriostatic Water intended for human use?
No. Bacteriostatic Water is supplied strictly for laboratory and in-vitro research use. It is not intended for human or veterinary consumption, diagnostic use, or therapeutic use, and RovaPeptides provides no dosing, protocol, or usage guidance.
