Renew Lab Group’s 50mL Bacteriostatic Water gives research teams a larger-volume, multi-draw diluent option without sacrificing the purity and consistency our smaller vial sizes are known for. Each 50mL vial is manufactured at our Houston, Texas facility under strict quality control protocols, using USP-grade water for injection preserved with 0.9% benzyl alcohol to inhibit bacterial growth across repeated withdrawals. This single-vial option is ideal for researchers who want to evaluate our product quality before committing to a multi-pack, or for labs that only need one larger-volume vial on hand for a specific study or protocol.
✔ USP-grade water for injection ✔ 0.9% benzyl alcohol preservative ✔ Batch-specific Certificate of Analysis included ✔ HPLC and endotoxin tested ✔ Sterile, multi-draw rubber stopper ✔ Manufactured in a CLIA-certified Houston facility
Every vial that leaves our facility is traceable back to its production batch, meaning the COA you receive reflects the exact lot in your hand rather than a generic specification sheet. This traceability is especially valuable for research teams that need to document reagent quality for internal audits, grant reporting, or peer review.
Why Researchers Choose Renew Lab Group Bacteriostatic Water
Bacteriostatic water is only as reliable as the manufacturing process behind it. Renew Lab Group controls every stage of production in-house, from water purification through final sterile filtration and vial filling, allowing us to guarantee batch-to-batch consistency in pH, osmolarity, and preservative concentration. Our 50mL format gives research teams a larger reservoir for reconstitution work that requires more frequent draws, reducing the number of vials that need to be opened, logged, and stored during an active study. Because the vial is designed for multiple sterile withdrawals, the rubber stopper is rated to maintain a consistent seal across repeated needle punctures, helping protect the remaining contents from contamination between uses.
Reconstitution Guidance for Research Use
This product is intended strictly for laboratory and research applications. It is not manufactured, labeled, or intended for human or animal administration. When used in a research reconstitution protocol, standard aseptic technique should always be followed: swab the stopper with an alcohol prep pad before each draw, use a new sterile syringe and needle for every withdrawal, and direct the stream slowly against the interior vial wall to minimize foaming or agitation of any lyophilized material. After first puncture, bacteriostatic water should be refrigerated and used within the timeframe specified by your institution’s protocols, since the benzyl alcohol preservative inhibits, but does not indefinitely prevent, microbial growth once the seal is broken.

Frequently Asked Questions
Is this product intended for human use?
No. This product is sold strictly for laboratory research purposes and is not intended for human or veterinary administration.
How many times can I draw from a single 50mL vial?
The stopper is designed for multiple sterile withdrawals, though the exact number of safe punctures depends on your protocol and storage conditions. Always follow your institution’s guidelines.
Does this vial come with a Certificate of Analysis?
Yes, every order includes access to the batch-specific COA reflecting HPLC and endotoxin results for your exact lot.
What is the shelf life after first use?
Once opened, refrigerate and use within the timeframe outlined by your lab’s internal protocols, as preservative effectiveness diminishes over time.
Can I order a larger multi-pack of 50mL vials?
Yes, this product is also available in 2-Pack, 5-Pack, and 10-Pack configurations for labs with higher-volume needs.
Where is this product manufactured?
All Renew Lab Group Bacteriostatic Water is produced at our CLIA-certified facility in Houston, Texas.
For laboratory and research use only. Not for human or animal use. Not for injection into humans. Not a drug, food, or cosmetic product.
