Description

✨ Product Overview & Core Positioning

Bacteriostatic Water, widely abbreviated as BAC Water, is a professional sterile solvent specially developed for laboratory research and peptide preparation scenarios, serving as a core auxiliary product for the dissolution, dilution and preservation of lyophilized peptides and research-based compounds. Different from ordinary single-use sterile water, our BAC Water is added with a precise proportion of 0.9% benzyl alcohol as a mild and efficient bacteriostatic preservative, which can effectively inhibit the growth and reproduction of common bacteria in the solution, greatly extending the usable time of the solution after opening and improving the cost performance and convenience of daily research operations.

Produced in a dust-free workshop that strictly complies with GMP production management standards, our BAC Water undergoes triple filtration, high-pressure sterilization and multi-layer quality testing in the whole production process, ensuring that each batch of products meets the requirements of non-pyrogenic, low endotoxin and high purity. It is a stable, safe and reliable supporting solvent for laboratory research, peptide reconstitution and related scientific research preparation, which can fully protect the activity and structural integrity of research compounds, avoid solution pollution and failure caused by bacterial contamination, and provide a solid guarantee for the smooth progress of research work.

🔬 Core Product Advantages & Performance Highlights

1. Strict Quality Control & Pharmaceutical Grade Purity

Our BAC Water is positioned at pharmaceutical grade purity standard, with the main component content of ≥99.9%, and no impurities, heavy metals or harmful additives that affect research results. The whole production process is under closed-loop monitoring, from raw material selection, purification treatment, filling and packaging to finished product inspection, each link has a complete quality control record. It has passed multiple tests such as sterility test, pyrogen test and endotoxin test, fully meeting the strict requirements of laboratory research on solvents, and is compatible with various high-precision research scenarios.

2. Moderate Preservative Formula & Long-Term Bacteriostatic Effect

We adopt a professional formula of 0.9% benzyl alcohol as a preservative, which is a safe and recognized bacteriostatic agent in the industry. It can inhibit the growth of most common bacteria in the solution without destroying the chemical structure and biological activity of peptides and research compounds. After the vial is opened, the solution can remain sterile and stable for up to 28 days when stored properly, supporting multiple repeated sampling and use, which is more economical and practical than single-use sterile water that needs to be discarded after one opening, greatly reducing the waste of research materials and daily use costs.

3. Excellent Compatibility & Stable Solvent Performance

Our BAC Water has a neutral and stable chemical property, is chemically inert to most peptide products, protein compounds and research-based preparations, will not undergo denaturation, decomposition or chemical reaction with the dissolved substances, and can fully maintain the stability and effectiveness of the research compounds. It is universally compatible with all types of lyophilized peptides on the market, and can be used for the dissolution, dilution and preservation of various research peptides, protein reagents and special compounds, with strong versatility and wide application scenarios.

4. Professional Sealed Packaging & Safe Transportation Protection

Each bottle of our BAC Water is filled and sealed in a dust-free sterile environment, adopting a thickened anti-breakage sealed glass vial, with a sealed rubber plug and an aluminum-plastic cap to realize double-layer sealing protection, effectively preventing air entry, bacterial contamination and solution leakage during storage and transportation. We also equip each product with a independent blister packaging box, which is moisture-proof, shockproof and light-proof, further enhancing the stability of storage and transportation, ensuring that each bottle of BAC Water delivered to customers is intact and in line with quality standards.

5. Two Conventional Sizes to Meet Different Usage Needs

We provide two mainstream specifications of 3ml and 10ml for customers to choose, which can be selected according to daily research frequency, usage amount and demand cycle. The 3ml small size is suitable for small-scale laboratory research and trial use, easy to carry and store; the 10ml large size is more cost-effective, suitable for long-term daily use and bulk demand, fully meeting the differentiated needs of different customers and research scenarios

🧪 Wide Application Scenarios & Usage Guidance

1. Core Application Fields

Reconstitution and dissolution of various lyophilized peptides, providing a sterile and stable solvent environment to ensure the full dissolution of peptide powders;
Dilution and proportioning of research-based hormones, protein reagents and special compounds, adjusting the concentration of research preparations to meet the needs of different research steps;
As a sterile solvent for basic biological research, cell research and in vitro experimental preparation, to ensure the sterility and stability of the experimental system;
Supporting mixing and preservation solvent for daily laboratory research, suitable for short-term storage of prepared research solutions (under sealed and low-temperature conditions).

2. Standard Usage Tips

Before use, please check the packaging integrity of BAC Water, do not use if the vial is damaged, leaked or expired;

When opening and using, please operate in a sterile environment, use sterile syringes and needles for sampling to avoid introducing external bacteria and causing solution pollution;

After each use, please re-seal the vial in time, store it in a cool and dark place, and use it up within 28 days after opening to ensure the best use effect;

This product is only used as a solvent for laboratory research and preparation, and is not used for other non-research purposes.

⚠️ Critical Compliance Reminder & Usage Restrictions

FOR RESEARCH USE ONLY. NOT FOR HUMAN OR VETERINARY INJECTION, ORAL ADMINISTRATION OR MEDICAL USE. This product is specially developed for laboratory research scenarios, and shall not be used for any human or animal clinical treatment, injection, oral administration and other medical-related behaviors, and shall not be used in violation of relevant national laws and regulations.
When storing BAC Water, please keep it out of the reach of children to avoid accidental contact or ingestion; at the same time, keep it away from high temperature, open fire and direct sunlight to ensure the stability of the product.
Due to product category and production process constraints, we do not provide a dedicated COA (Certificate of Analysis) for pre-filled BAC Water vials. Customers who have strict requirements for relevant documents need to confirm clearly before placing an order to avoid unnecessary misunderstandings.
Before use, please confirm that you have professional laboratory operation knowledge and sterile operation skills, and use in strict accordance with laboratory research specifications to avoid operational errors affecting the use effect.

📦 Packaging Rules & Ordering Instructions

Our BAC Water is sold in the form of independent vials, and customers can choose the combination of 3ml and 10ml specifications according to their needs. In order to ensure the efficiency of production, packaging and transportation, the minimum order quantity of single specification is 50 vials, and bulk orders can enjoy more favorable price support.

It should be noted that BAC Water is an independent solvent product, and the injection pens, peptide products and other supporting tools involved in the use process need to be purchased separately.
