Certificate of Analysis (COA) Library
Access official analytical documentation, third-party laboratory verification, and lot-specific quality control certificates for all BacScience laboratory-grade materials.
The COA Library serves as a central repository for independent testing documentation. Every batch of BacScience material undergoes comprehensive analytical screening—including purity verification, sterility confirmation, endotoxin limit testing, and preservative concentration assays—documented in publicly accessible Certificates of Analysis.

How to Interpret a BacScience COA
A Certificate of Analysis (COA) provides documented confirmation that a specific batch meets pre-established specifications and analytical standards.
1. Header & Traceability Metadata
Identifies the manufacturing lot number, production date, testing facility, and sample control identifiers ensuring material continuity.
2. Analytical Specifications
Outlines the target parameter range, reference testing standards (e.g., USP monographs), and acceptable standard thresholds.
3. Quantitative Results
Details actual measured values from high-performance liquid chromatography (HPLC), mass spectrometry, or microbiological culturing.
4. Authorization & Quality Sign-off
Features formal approval signatures from accredited Quality Assurance (QA) personnel and independent analytical chemists.
Core Quality Parameters Screened
Every batch listed in the archive is subjected to mandatory quality evaluation criteria prior to release.
| Test Parameter | Analytical Methodology | Specification Target |
|---|---|---|
| Microbiological Sterility | 14-Day Direct Inoculation / Membrane Filtration | No microbial growth detected |
| Bacterial Endotoxins | Limulus Amebocyte Lysate (LAL) Kinetic Chromogenic | < 0.25 EU/mL |
| Preservative Concentration | HPLC Analysis (Benzyl Alcohol Assay) | 0.9% w/v (±0.05%) |
| pH Balance | Potentiometric pH Measurement | 4.5 – 7.0 |
| Particulate Matter | Light Obscuration Particle Count Test | Meets USP <788> limits |

Contact Quality AssuranceCOA Library FAQs
Where do I find the lot number on my product?
The lot or batch number is printed on the physical vial label, as well as on the outer protective packaging. It typically begins with a prefix such as "BS-BW-" followed by the production year and sequence code.
Are testing reports conducted internally or by independent laboratories?
All COAs in our library are generated based on testing conducted by ISO/IEC accredited third-party analytical laboratories to maintain strict independent verification standards.
What should I do if my lot number is not listed in the archive?
New lot records are added routinely upon completion of testing cycles. If your batch number is not visible, contact customer support with your lot identifier to receive a direct digital copy of the certificate.
