Our Lab — Inside the Renew Lab Group Cleanroom Facility

Every vial of Renew Lab Group bacteriostatic water is produced in our Houston, TX ISO-compliant cleanroom under controlled conditions designed to meet pharmaceutical-grade quality standards.

Our Manufacturing Facility — Built for Research Integrity

Renew Lab Group’s production facility is located in Houston, Texas — the city that houses the Texas Medical Center, the world’s largest medical complex. Our proximity to this extraordinary research ecosystem is not coincidental. It means we operate under the scrutiny of thousands of world-class researchers, clinicians, and quality professionals who set the highest standards for what “pharmaceutical grade” actually means.

Our cleanroom is ISO-compliant, designed and operated to control particulate contamination, microbial load, temperature, humidity, and pressure differentials that could compromise product sterility or purity. This is not a repacking operation or a garage lab — it is a professional pharmaceutical manufacturing environment built from the ground up for research-grade BAC water production.

The Cleanroom Environment — Controlled at Every Level

🌡️ Temperature Control

Production areas maintained at controlled temperature ranges to prevent thermal degradation of bacteriostatic water components during manufacturing and filling. Temperature is monitored continuously with calibrated sensors and data logging.

💧 Humidity Control

Controlled relative humidity in production areas prevents moisture-related issues during pharmaceutical compounding operations. Humidity is monitored and documented as part of our environmental monitoring program.

🔬 HEPA Filtration

HEPA-filtered air supply removes airborne particulates that could contaminate product during filling and sealing operations. Air quality is monitored through environmental sampling as part of our quality program.

🏭 Pressure Differentials

Positive pressure differentials prevent contaminated air from flowing into cleaner zones. Our facility maintains appropriate pressure cascades between production areas, gowning zones, and external environments.

👔 Personnel Controls

All personnel entering production areas follow documented gowning procedures. Behavior in cleanroom environments is governed by written SOPs (Standard Operating Procedures) to minimize contamination risk from human activity.

🧹 Cleaning Validation

Production equipment and cleanroom surfaces are cleaned and sanitized per validated procedures between production runs. Cleaning validation ensures that no residual contamination from previous runs can affect the next batch.

The Production Process — From Raw Material to Sealed Vial

Step 1: Raw Material Qualification

Every incoming raw material used in bacteriostatic water production is received with supplier documentation and subject to our incoming inspection protocol. This includes verification of identity, certificate of analysis review, and physical inspection before any material is accepted into production.

Step 2: Purified Water System

Our production water meets pharmaceutical-grade specifications. The water purification system is maintained and monitored to ensure consistent quality of the water used as the primary component of bacteriostatic water. Conductivity, TOC (Total Organic Carbon), and microbial quality are tested regularly.

Step 3: Formulation

Benzyl alcohol is added to purified water at the specified 0.9% concentration using calibrated measuring equipment. pH is adjusted and verified to fall within the 4.5–7.0 specification. In-process testing confirms formulation parameters before proceeding to filling.

Step 4: Sterile Filtration and Filling

The formulated bacteriostatic water is sterile-filtered through 0.22 micron membrane filters before aseptic filling into pharmaceutical-grade glass vials. Filling is performed in the ISO-compliant cleanroom environment under laminar airflow conditions. Vials are sealed with pharmaceutical-grade rubber stoppers and crimp-sealed aluminum caps.

Step 5: Batch Testing

Every filled batch undergoes our full testing panel before release:

HPLC Purity Analysis — benzyl alcohol concentration and overall chemical purity
LAL Endotoxin Testing — quantitative endotoxin measurement, result documented in EU/mL
USP 71 Sterility Testing — confirmation of no viable microorganisms
pH Testing — verification of 4.5–7.0 range
Visual Inspection — clarity, particulate-free, container closure integrity
Benzyl Alcohol Assay — specific quantification of bacteriostatic agent concentration

Step 6: Batch Release

A batch is only released when all test results pass all acceptance specifications. The passing results are compiled into the batch-specific Certificate of Analysis. No batch is shipped before this documentation is complete. The COA that ships with your order is the actual documentation for your specific batch — not a generic template or a lot certificate that may cover thousands of vials manufactured over months.

Step 7: Storage and Fulfillment

Released product is stored in controlled conditions pending fulfillment. Orders are picked, packed, and shipped same day (for orders received before 2 PM CST) using carriers appropriate for the transit distance and time requirements. All shipments are tracked and confirmations are sent automatically.

Why Texas Medical Center Sets the Standard We Build To

The Texas Medical Center encompasses MD Anderson Cancer Center (ranked #1 cancer hospital in the US), Houston Methodist Hospital, Memorial Hermann, Texas Children’s Hospital, Baylor College of Medicine, UTHealth Houston, UT MD Anderson, and dozens of other world-class institutions. When your nearest research neighbors are operating at this level, you build your quality systems to meet their expectations. The TMC community is our home market — and serving them well means building the cleanroom, the testing program, and the documentation system that serious research demands.
