Why bacteriostatic water for reconstitution
Lyophilized research peptides ship as a dry powder and must be reconstituted into solution before use in an assay. Bacteriostatic water is sterile water containing 0.9% benzyl alcohol, a preservative that suppresses microbial growth across repeated stopper entries — which is why it is the standard diluent for multi-dose research vials. The benzyl alcohol allows a reconstituted vial to be drawn from over several days of bench work rather than a single use.
How much to add
The volume of bacteriostatic water you add sets the working concentration of your reconstituted peptide. As a worked example, adding 2 mL of diluent to a 5 mg vial yields 2,500 mcg/mL; adding 1 mL yields 5,000 mcg/mL. Use the reconstitution calculator linked from every product page to convert a vial size and target concentration into an exact diluent volume, then add it slowly down the inside wall of the vial and swirl gently rather than shaking.
Storage after reconstitution
Hold reconstituted, preserved vials at 2-8 °C protected from light and use within the working window your protocol specifies. Bacteriostatic water itself is stored at room temperature away from light until opened. Keep one 30 mL vial on the bench for every few lyophilized SKUs — a single 30 mL fill reconstitutes many standard peptide vials.
Documentation
Each lot ships with a fill record and a research-use-only disclosure. As a reconstitution supply rather than a peptide, bacteriostatic water is provided for laboratory handling of the research reagents in this catalog.
Research guide
Bacteriostatic Water research overview
Bacteriostatic Water is listed as a research-use-only material for qualified laboratory programs. This page connects the product listing with identity fields, storage context, CoA review, and long-form research resources so procurement and QA reviewers can evaluate the SKU without relying on a thin commerce page.
The catalog classifies this material as Reconstitution supply (research), which helps labs compare it with adjacent research peptides, organize internal inventory, and build study-specific reference groups.

Storage and handling context
For long-tail stability searches, Bacteriostatic Water should be evaluated in the context of lyophilized storage, reconstitution buffer choice, aliquot planning, freeze-thaw limits, and lot-specific CoA conditions. Always follow institutional SOPs and the documentation attached to the received lot.
Mechanism context
Bacteriostatic Water should be described through published model-system language: receptor family, pathway context, assay controls, concentration planning, and lot traceability. Avoid transferring assumptions from adjacent peptides without a documented comparison protocol.

Product FAQ
Is Bacteriostatic Water intended for clinical programs?
No. BluGen listings are research use only (RUO) materials for qualified laboratory programs, not clinical, diagnostic, therapeutic, veterinary, food, drug, or cosmetic use.
What documentation is available for Bacteriostatic Water?
Lot-level documentation may include CoA, HPLC purity, MS identity confirmation, net peptide content, and batch records where available for the SKU and lot.
How should lyophilized Bacteriostatic Water be stored?
Store sealed lyophilized vials cold, dry, and protected from light unless the lot CoA or institutional SOP specifies another condition. Reconstituted material should be aliquoted according to the lab protocol.
Where can I learn more about Bacteriostatic Water research context?
See the BluGen research guide for mechanism context, stability notes, storage considerations, and related peptide comparisons: https://getblugen.com/research/
What is the research category for Bacteriostatic Water?
Bacteriostatic Water is categorized as Reconstitution supply (research) for catalog organization, internal linking, and related research comparisons.
What sequence is listed for Bacteriostatic Water?
Sequence identity should be verified against the lot-specific CoA and product identity table before release into a research workflow.
What molecular weight is listed for Bacteriostatic Water?
Molecular weight should be verified from the product identity table and lot CoA before concentration calculations.
Does Bacteriostatic Water require cold storage?
Most lyophilized research peptides are stored cold, dry, sealed, and protected from light unless the lot CoA or institutional SOP states otherwise.
How should reconstituted Bacteriostatic Water be handled?
Reconstituted research stocks should be labeled with SKU, lot, solvent, concentration, date, and technician initials, then aliquoted according to the lab protocol to limit freeze-thaw history.
Can lots of Bacteriostatic Water be mixed together?
Avoid mixing lots unless a written protocol requires it. Mixed-lot stocks reduce traceability and make CoA review more difficult.
What purity documentation matters for Bacteriostatic Water?
HPLC purity, MS identity, net peptide content, moisture or residual summaries where available, and lot number alignment are the core documentation checks.
What does net peptide content mean for Bacteriostatic Water?
Net peptide content accounts for peptide mass apart from water and counter-ion contribution. It is important for molarity calculations in laboratory records.
What should procurement review before ordering Bacteriostatic Water?
Procurement should review SKU, vial size, lot documentation path, RUO status, storage requirements, shipping expectations, and any internal approval requirements.
How should Bacteriostatic Water be cited in a method record?
Record supplier, SKU, lot number, CoA document ID, reconstitution solvent, stock concentration, storage condition, and date prepared.
What are common related resources for Bacteriostatic Water?
Related resources include the peptide storage guide, reconstitution guide, CoA reading guide, purity guide, and any comparison articles linked from the product page.
Why does BluGen link Bacteriostatic Water to research articles?
Internal article links help buyers evaluate identity, storage, documentation, and research context without relying on a thin product listing.
What should be done if Bacteriostatic Water documentation is incomplete?
Hold the lot in review and request the missing CoA or batch documentation before releasing the material into an internal research workflow.
Is Bacteriostatic Water content on BluGen medical advice?
No. BluGen content is laboratory procurement and research documentation content for RUO materials only.
