Introduction
Not all laboratory supplies are manufactured to the same quality standards.
When purchasing bacteriostatic water, quality documentation and manufacturing practices matter.
1. USP-Grade Components
Look for products manufactured using USP-grade materials whenever applicable.
2. Type I Borosilicate Glass
Premium products often use:
- USP Type I borosilicate glass
- Pharmaceutical-grade rubber stopper
- Aluminum crimp seal
3. Sterility Testing
Manufacturers should perform routine sterility testing during production.
4. Certificate of Analysis
A Certificate of Analysis demonstrates that manufacturing quality checks have been completed.
Typical information includes:
- Batch number
- Manufacturing date
- Sterility testing
- Appearance
- Endotoxin testing
- Quality approval
5. Tamper-Evident Packaging
Good packaging should include:
- Secure cap
- Aluminum seal
- Leak-resistant closure
- Protective packaging
6. Batch Traceability
Each vial should include:
- Lot number
- Expiration date
- Manufacturing information
7. Professional Labeling
Labels should clearly display:
- Product name
- Volume
- Preservative information
- Manufacturer
- Lot number
Why Documentation Matters
Professional laboratories value products that include:
- Manufacturing consistency
- Quality records
- Batch traceability
- Certificate of Analysis
These features support transparency and quality assurance.
