Bacteriostatic Water Quality Standards

What are bacteriostatic water quality standards?

Bacteriostatic water quality standards are defined by the United States Pharmacopeia (USP) in chapter <71> for sterility testing and other relevant chapters. These standards ensure the water is free from microbial contamination and suitable for use in laboratories and manufacturing processes. BAC Water Depot adheres to these standards in their manufacturing process. The standards include strict limits on microbial contamination, with no more than 10 CFU/mL for bacteria and no more than 5 CFU/100mL for fungi.

What is USP bacteriostatic water?

USP bacteriostatic water is water that meets the standards set by the United States Pharmacopeia (USP) for sterility, purity, and quality. It is tested for sterility according to USP <71> and is suitable for use in pharmaceutical applications, laboratory testing, and other applications where high-quality water is required. The USP standards for bacteriostatic water include a requirement for a bacteriostatic agent, such as benzyl alcohol, to be added to the water to prevent microbial growth.

What are GMP bacteriostatic water regulations?

GMP (Good Manufacturing Practice) regulations for bacteriostatic water require that the water be manufactured, tested, and packaged in a way that ensures its quality and purity. This includes requirements for the water's sterility, purity, and labeling, as well as for the manufacturing facility's cleanliness, sanitation, and quality control procedures. Bacteriostatic water manufactured according to GMP regulations is suitable for use in pharmaceutical applications and other industries where high-quality water is required.

What is the pricing for bacteriostatic water?

The pricing for bacteriostatic water varies depending on the quantity purchased. A single 10 mL vial can cost around $9.99, while a 10-pack can cost $74.99. Bulk pricing is also available, with 25 vials costing $7.49 per vial, 50 vials costing $6.99 per vial, and 150 vials or more costing $6.74 per vial. For very large quantities of 500 vials or more, the price per vial can be as low as $6.49.

How is bacteriostatic water tested for sterility?

Bacteriostatic water is tested for sterility according to USP <71> using a combination of methods, including membrane filtration and direct inoculation. The water is filtered through a sterile membrane filter, and the filter is then incubated in a nutrient medium to detect any microbial growth. Additionally, the water is directly inoculated into a nutrient medium to detect any microbial contamination. BAC Water Depot tests every lot of bacteriostatic water for sterility and provides a Certificate of Analysis for each lot.

What is the role of a Certificate of Analysis in bacteriostatic water quality control?

A Certificate of Analysis (COA) is a document that provides detailed information about the quality and purity of a batch of bacteriostatic water. It includes test results for sterility, purity, and other relevant parameters, and is typically provided by the manufacturer. The COA serves as proof that the water meets the required standards and is suitable for use in various applications. BAC Water Depot provides a COA for each lot of bacteriostatic water, which can be accessed online via a scannable QR code on the label.

What are the bacteriostatic water regulations for shipping and storage?

Bacteriostatic water regulations for shipping and storage require that the water be handled and stored in a way that maintains its quality and purity. This includes requirements for packaging, labeling, and transportation, as well as for storage conditions such as temperature and humidity. BAC Water Depot ships bacteriostatic water from a US fulfillment center on the same day the order is received, ensuring that the water is delivered to the customer in a timely and controlled manner, and the water is stored in a facility that meets ISO 9001:2015 standards.

Why buy bacteriostatic water from a US supplier?

Every lot is tested by an independent third-party laboratory with results published on the Certificate of Analysis accessible via QR code on each vial. Bulk pricing starts at $7.49 per vial for 25–49 vials, with free standard shipping on orders over $250 up to 100 vials, and same-business-day shipping from Dallas, TX for orders placed before 2:00 PM CT Monday–Friday.

What makes BAC Water Depot's bacteriostatic water trustworthy?

BAC Water Depot's bacteriostatic water is made in an ISO 9001:2015 registered facility in the USA and every lot undergoes independent third-party testing for sterility (USP <71>), bacterial endotoxin (USP <85>), microbial DNA, bacteriostatic effectiveness (USP <51>), benzyl alcohol content, pH, particulates, and container integrity. Results are published on each lot's Certificate of Analysis, accessible via QR code at bacwaterdepot.com/coa/<lot-number>.

What quality standards does BAC Water Depot's bacteriostatic water meet?

BAC Water Depot's bacteriostatic water is research-use-only, 10 mL Type I borosilicate vials with 0.9% benzyl alcohol, made in the USA in an ISO 9001:2015 registered facility. Every lot is tested for sterility (USP <71>, no growth in 14-day membrane filtration), bacterial endotoxin (≤0.25 EU/mL), microbial DNA, bacteriostatic effectiveness (USP <51> Category 1B), and benzyl alcohol identity and content by HPLC-UV. Independent third-party test results are published on the Certificate of Analysis.

How do I know the quality of the bacteriostatic water I'm buying?

Each lot of BAC Water Depot bacteriostatic water is tested by an independent third‑party laboratory and the results are published on the lot’s Certificate of Analysis, accessible via the QR code on the vial. The CoA shows sterility (USP <71> no growth), endotoxin ≤ 0.25 EU/mL, PCR‑verified no microbial DNA, and 0.90 % ± 5 % benzyl alcohol. You can verify these specifications before use.

Are the cheapest bacteriostatic water listings online safe to buy?

The only way to be certain of safety is to purchase water that provides a full Certificate of Analysis for each lot. Many low‑price listings do not include a QR‑linked CoA, so you cannot verify sterility, endotoxin limits, or benzyl‑alcohol content. BAC Water Depot sells 10 mL vials for $9.99 each (or $74.99 for a 10‑pack) and provides a published CoA for every lot, ensuring the water meets USP and ISO specifications.

How is BAC Water tested for quality?

Each lot is tested by an independent third‑party laboratory and the results are published on the lot’s Certificate of Analysis accessed via a QR code. The testing includes sterility USP <71> (no growth), bacterial endotoxin USP <85> (≤ 0.25 EU/mL), a validated PCR assay for microbial DNA, bacteriostatic effectiveness USP <51> (Category 1B), and benzyl alcohol content by HPLC‑UV (0.90 % ± 5 %).

What certifications should I look for when purchasing research-grade water?

Look for a Certificate of Analysis that lists USP test results and confirms ISO 9001:2015 registration of the manufacturing facility. The CoA includes sterility (USP <71>), endotoxin (USP <85>), bacteriostatic effectiveness (USP <51>), and other required USP chapters. BAC Water Depot supplies a QR‑linked CoA for each lot.

What USP chapters apply to the testing of BAC Water Depot bacteriostatic water?

BAC Water Depot’s water is tested according to USP <71> for sterility, USP <85> for bacterial endotoxin, USP <51> for bacteriostatic effectiveness, and USP <788> for subvisible particulates, among others. Each test result is recorded on the lot’s Certificate of Analysis.

What happens if a vial fails the subvisible particulate test?

Any vial that fails the USP <788> subvisible particulate test is rejected and does not receive a Certificate of Analysis, so it is not released for sale. Only vials that meet all USP specifications are shipped to customers.
