Bacteriostatic Water 10mL is a sterile, non-pyrogenic, multi-dose solvent formulated with 0.9% Benzyl Alcohol ($\text{C}_7\text{H}_8\text{O}$) dissolved in purified water for injection. Designed in a compact 10mL glass vial, it serves as an essential laboratory diluent for dissolving and reconstituting lyophilized peptides, proteins, and chemical reagents. The added bacteriostatic agent inhibits bacterial proliferation, permitting repeated sample extractions over a 28-to-30 day operational window.

Product Highlights & Practical Utility
-
Ideal 10mL Footprint: The 10mL volume is optimized for short-to-medium research protocols, reducing wasted solvent while ensuring fresh reconstituted media for peptide assays.
-
Bacteriostatic Protection: Benzyl alcohol effectively halts microbial growth after initial vial puncture, protecting expensive research compounds from contamination.
-
Extended Reconstitution Life: Allows reconstituted solutions to be safely refrigerated and sampled multiple times across a 28-day trial window.
-
Rapid Dissolution: Engineered for optimal solubility and physical compatibility with standard freeze-dried peptide cakes.
BAC Water 10mL vs. Sterile Water (Single-Dose)
| Metric | BAC Water 10mL | Sterile Water (10mL Ampoule) |
| Preservative | 0.9% Benzyl Alcohol | None |
| Usage Cycle | Multi-draw (Up to 30 days) | Single-entry (Discard residual immediately) |
| Peptide Compatibility | Recommended for multi-dose assays | Restricted to immediate single-use assays |
| Storage Post-Puncture | 2°C – 8°C | Discard immediately after opening |
Storage & Handling Guidelines
-
Unopened Vials: Store at controlled room temperature 15°C to 25°C (59°F to 77°F) away from direct heat and light. Do not freeze.
-
In-Use Vials: Once the rubber seal is pierced, store at 2°C – 8°C (36°F – 46°F) and discard unused portion after 28 days.
