Description
Why Researchers Choose the 3mL Format
- Precision Single-Vial Format: Calibrated for reconstituting one or two peptide vials with minimal waste — no leftover solvent to discard.
- Same USP-Standard Formulation: Identical composition to the 10mL format — sterile, non-pyrogenic water with 0.9% benzyl alcohol preservative.
- Reduced Waste Protocol: Eliminates the common problem of discarding unused bacteriostatic water when the 28-day window expires before a 10mL vial is depleted.
- Universal Peptide Compatibility: Works with every lyophilized peptide in the Peptideware catalog, from individual compounds to complex blends.
- Ideal for Focused Research: Perfect for researchers working with a single peptide compound who need exact volume control without excess.
Frequently Asked Questions
What is the 3mL format best for?
The 3mL bacteriostatic water vial is designed for single-peptide reconstitution protocols. It provides exactly the volume needed for one or two standard peptide vials (typically 1–3mL per reconstitution) with minimal leftover, eliminating the waste that occurs when larger volumes expire before use.
How does the 3mL differ from the 10mL?
The formulation is identical — both contain USP-standard sterile water with 0.9% benzyl alcohol at the same pH (~5.7). The only difference is volume. The 3mL format is designed for single-use efficiency, while the 10mL format serves researchers who reconstitute multiple vials within a 28-day period.
Can I use 3mL bacteriostatic water for any peptide?
Yes. This bacteriostatic water is compatible with all lyophilized peptides, including individual compounds (BPC-157, TB-500, GHK-Cu, KPV, Melanotan II, and others) as well as blends like GLOW and KLOW. The pH and preservative concentration are optimized for broad amino acid sequence compatibility.
How should the 3mL vial be stored?
Store sealed vials at room temperature (15–30°C) away from direct light. After first puncture, refrigerate at 2–8°C and use within 28 days. Do not freeze, as this can alter benzyl alcohol concentration.
When should I choose 3mL vs 10mL?
Choose the 3mL format when reconstituting 1–2 peptide vials — it provides fresh solvent with zero waste. Choose the 10mL format when working with 3 or more vials, running longitudinal studies, or maintaining multiple reconstituted peptides simultaneously within the 28-day active window.

The “Zero Waste” Efficiency Protocol
Standard 10mL or 30mL solvent vials often present a logistical inefficiency for researchers working with individual peptide units: once punctured, the “28-Day Clock” begins, often resulting in the disposal of large volumes of unused solvent.
The 3mL Format is the “Goldilocks” solution for single-vial reconstitution:
-
The Fresh Advantage: Ensure your high-value lyophilized peptides are always introduced to a newly opened, pristine solvent source.
-
Cost & Waste Reduction: Eliminate the practice of discarding expired bulk solvents. This vial provides exactly what is needed for 1-2 standard peptide vials (e.g., 5mg or 10mg concentrations) with minimal leftover volume.
This research peptide undergoes rigorous quality control and stability testing to ensure maximum integrity for scientific applications. Each batch is manufactured under strict laboratory conditions and verified through independent laboratory analysis.⚠️ FOR RESEARCH PURPOSES ONLY
This product is strictly for in-vitro laboratory research and analytical use. It is not intended for therapeutic use, human consumption, or direct injection without professional oversight. Keep out of reach of children. Discard any remaining solution 28 days after the initial puncture.
Technical Specifications
Unlike cheaper plastic ampoules often found in generic kits, our 3mL solvent is contained in laboratory-grade glassware to ensure chemical inertness.
-
Container: Type I Borosilicate Glass Vial. This medical-grade glass prevents chemical leaching and maintains the integrity of the solution during long-term storage.
-
Preservative: 0.9% Benzyl Alcohol (9mg/mL). Allows for multiple withdrawals within the active window without compromising sterility.
-
pH Optimization: Buffered to an approximate pH of 5.7. This range is chemically optimized to facilitate the dissolution of amino acid chains without inducing hydrolysis or degradation.
Usage Application
This 3mL volume is specifically calibrated for:
-
Single-Vial Reconstitution: Perfect for adding 1mL, 2mL, or 3mL to a standard 3mL peptide vial.
-
Field/Portable Research: Ideal for compact storage where bulk 30mL bottles are impractical.
