Bacteriostatic Water 30ml – 2 Pack
Bacteriostatic Water 30ml – 2 Pack is 2 sealed vials (60 mL total) of bacteriostatic water: sterile water preserved with 0.9% benzyl alcohol so a vial can be accessed more than once. It is manufactured by Renew Lab Group in Houston, Texas, tested in our own licensed HPLC lab, and covered by a Certificate of Analysis that is run monthly for each production batch. The 30 mL fill is a larger multi-draw size for steady weekly use. This pack gives you two vials, so a backup is on the shelf when the first one is opened. For Research Use Only.
Highlights
- Preserved for multi-draw use – 0.9% benzyl alcohol slows microbial growth after the stopper is punctured, which is what separates bacteriostatic water from preservative-free sterile water.
- Tested in our own lab – Benzyl alcohol content is verified by HPLC, and each batch is tested for endotoxin (LAL method), pH and sterility before release.
- Monthly batch COA – A Certificate of Analysis is run monthly and covers each production batch made that month, so the batch you receive is covered by that month’s results.
- Cleanroom manufacturing – Filled in Houston, Texas in our ISO 5/ISO 7 cleanroom environment.
- Sealed vials – Glass vials with a rubber stopper and tamper-evident aluminum crimp seal.
What is bacteriostatic water?
Bacteriostatic water is sterile water that contains a small amount of preservative, most commonly 0.9% benzyl alcohol. “Bacteriostatic” means the preservative inhibits the growth of bacteria rather than killing them, which is why it suits a vial that will be entered several times. Sterile water without a preservative is meant for single use. In research settings, bacteriostatic water is used as a diluent to dissolve lyophilized (freeze-dried) materials into solution under the lab’s own protocol.
How it is made and tested
Renew Lab Group controls the whole process in Houston: water purification, preservative addition, sterile filtration, filling and sealing. Our analytical lab then tests each batch. HPLC confirms the benzyl alcohol concentration, LAL testing measures bacterial endotoxin, and sterility testing checks for microbial growth. The same lab offers these tests to outside clients; see HPLC Lab Testing Services.

Handling and storage
- Store unopened vials at controlled room temperature, away from direct light.
- Use aseptic technique: swab the stopper before each entry and use clean, sterile equipment.
- Once a vial is punctured, label it with the date and follow your institution’s protocol for storage and discard dates.
- Do not use if the seal is broken or the liquid is cloudy, discolored or contains particles.
Bacteriostatic or sterile water?
Choose bacteriostatic water when a vial will be entered more than once and benzyl alcohol is compatible with your protocol. Choose preservative-free sterile water when your protocol excludes benzyl alcohol or calls for single use.

Frequently Asked Questions
What is bacteriostatic water?
Bacteriostatic water is sterile water preserved with 0.9% benzyl alcohol. The preservative inhibits bacterial growth after a vial is punctured, so one vial can be accessed more than once. It is sold here for research use only.
What is the difference between bacteriostatic water and sterile water?
Bacteriostatic water contains 0.9% benzyl alcohol as a preservative and is made for multi-draw vials. Sterile water for injection has no preservative and is meant for single use, which suits protocols that exclude benzyl alcohol. We sell both in 30 mL vials.
How many vials come in this pack?
This pack contains 2 sealed 30 mL vials, 60 mL in total, for $23.38, or $11.69 per vial.
Is there a Certificate of Analysis?
Yes. A Certificate of Analysis is run monthly and covers each production batch made that month, with results including benzyl alcohol content by HPLC, pH, endotoxin and sterility. It is not issued per shipment. For COA questions, call 936-379-5515 or email info@renewlabgroup.com.
How should I store bacteriostatic water?
Store unopened vials at controlled room temperature, away from direct light. After a vial is punctured, date it and follow your institution’s protocol for storage and discard. Do not use it if the liquid is cloudy or discolored or the seal is broken.
Which vial size should I choose?
All sizes use the same formula. Smaller vials (10 mL) mean a fresh vial is opened more often; larger vials (30 and 50 mL) suit higher-volume work and cost less per mL. Packs of 2, 5 and 10 lower the price per vial.
Is this product for human or veterinary use?
No. Renew Lab Group bacteriostatic water is sold for research use only. It is not intended for human or veterinary use and is not a drug, food or cosmetic.
