💧 What is Bacteriostatic Water?

Bacteriostatic Water is a sterile preparation of Water for Injection that contains 0.9% (9 mg/mL) benzyl alcohol added as a bacteriostatic preservative . Unlike sterile water for injection, which lacks a preservative and must be discarded immediately after a single use, bacteriostatic water is designed for multiple-dose vials . The presence of benzyl alcohol inhibits the growth of microorganisms, allowing researchers to make repeated, aseptic withdrawals from a single vial over a specified period, typically up to 28 days after the first puncture . This makes it an indispensable and economical solvent for laboratories engaged in ongoing research with sensitive materials.

Its primary function is to act as a vehicle for diluting, dissolving, or reconstituting water-soluble substances—such as peptides, proteins, and enzymes—that are stable only in a lyophilized (freeze-dried) state . It is formulated to be non-pyrogenic (free of fever-inducing agents) and meets stringent sterility requirements .

🔎 Product Specifications & Technical Data

To ensure your research parameters are met with precision, here are the verified technical specifications for our Bacteriostatic Water. Sterility and accurate composition are critical for research reproducibility .

🧪 Key Research Applications & Focus Areas

Bacteriostatic water is a foundational reagent across numerous life science disciplines.

• 🔬 Peptide Reconstitution: This is the most common application. Lyophilized peptides are highly susceptible to hydrolysis and microbial contamination. Bacteriostatic water provides a sterile, preserved environment for dissolving them into stock solutions, enabling accurate dosing and extended usability for in vitro studies .
• 🧪 Protein and Antibody Preparation: In biochemistry and immunology, researchers use bacteriostatic water to prepare working solutions of proteins and antibodies from lyophilized stocks, ensuring their stability for assays like ELISA or Western blotting over multiple uses .
• 💊 Pharmaceutical Research: In drug development and pharmacokinetic studies, sterility is paramount. This solution is used to dilute or dissolve research-grade compounds for precise administration in pre-clinical models, ensuring that the vehicle itself does not introduce variables .
• 🧬 Buffer and Media Preparation: For sensitive cell culture or biochemical assays, it can be used as a base for creating sterile buffers and solutions, where maintaining a contaminant-free environment is essential for validity.
• ⚗️ General Laboratory Solvent: It serves as a general-purpose sterile solvent for dissolving various water-soluble research reagents that require a preserved, multi-use format .

📝 Handling, Storage, and Preparation for Research

Proper handling is critical to maintaining sterility and ensuring experimental validity .

• ❄️ Winter Shipping Warning: Be aware that this product is susceptible to freezing during transit in colder climates. If the solution arrives frozen or with ice crystals, its chemical integrity and sterile properties may be compromised. Do not use if frozen, even if it returns to liquid form .
• Receiving & Storage: Upon receipt and confirmation of no freezing, store the vial at controlled room temperature (20-25°C) as indicated on the label . Do not freeze.
• Aseptic Technique is Mandatory: Before each use, wash hands and swab the vial’s rubber stopper thoroughly with a 70% alcohol swab. Always use a new, sterile needle and syringe for each withdrawal to prevent contamination .
• In-Use Period: Once the vial is punctured for the first time, mark the date on the vial. Discard any unused solution after 28 days, even if some liquid remains .
• Visual Inspection: Before each use, inspect the solution. It must be clear and free of particulates, cloudiness, or discoloration. Do not use if the solution appears compromised or if the vial’s seal is broken .
• Reconstitution Guidelines: When reconstituting a peptide, inject the bacteriostatic water slowly down the inner wall of the peptide vial to avoid vigorous shaking, which can damage the peptide’s structure. Gently swirl until dissolved .
• Safety & Handling: Always use personal protective equipment (PPE). Bacteriostatic water is for research use only. Dispose of needles, syringes, and vials in appropriate sharps and biohazard containers according to institutional guidelines .

❓ Frequently Asked Questions (FAQ)

Q1: What is the difference between Bacteriostatic Water and Sterile Water for Injection?

A: The key difference is the presence of 0.9% benzyl alcohol in bacteriostatic water, which acts as a preservative . Sterile water has no preservative and is intended for single-use only; any unused portion must be discarded immediately to prevent microbial growth . Bacteriostatic water’s preservative allows for multiple, safe withdrawals from the same vial over up to 28 days .

Q2: Why is 0.9% benzyl alcohol used?

A: At a concentration of 0.9% (9 mg/mL) , benzyl alcohol effectively inhibits the growth of bacteria that could be introduced during repeated needle punctures, thereby maintaining the sterility and extending the usable life of the solution in a multi-dose vial .

Q3: How long is a vial good for after I open it?

A: With proper storage at room temperature and strict adherence to aseptic technique (swabbing the stopper with alcohol, using sterile needles), the vial should be used within 28 days of the first puncture .

Q4: How do I verify the quality of your Bacteriostatic Water?

A: We are committed to transparency. Our product listings provide access to a Certificate of Analysis (COA), which confirms the solution meets specifications for sterility, endotoxin levels (<0.5 EU/mL), pH (4.5-7.0), and preservative content .

Q5: What should I do if my Bacteriostatic Water freezes during shipping?

A: Do not use it. If this product has frozen, its chemical integrity and sterile properties may be compromised. Please contact our support team immediately for assistance with a replacement .
