Sterile Water for Injection 20ml – 1 Pack
Sterile Water for Injection 20ml – 1 Pack is one sealed 20 mL vial of preservative-free sterile water for research protocols where benzyl alcohol is not wanted. 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. Because it contains no preservative, single use is recommended. For Research Use Only.
Highlights
- Preservative-free – No benzyl alcohol or other preservative, for protocols where a preservative would interfere.
- Single-use vial – Without a preservative, a punctured vial isn’t protected against microbial growth, so use it once and discard the remainder per your protocol.
- Tested in our own lab – Each batch is HPLC tested and 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.
- Cleanroom manufacturing – Filled in Houston, Texas in our ISO 5/ISO 7 cleanroom environment.
What is sterile water for injection?
Sterile water for injection (SWFI) is purified water that has been sterilized and packaged without any added preservative, salt or buffer. In research settings it is used as a preservative-free diluent for lyophilized materials and other preparations when the protocol calls for plain sterile water. Its counterpart, bacteriostatic water, adds 0.9% benzyl alcohol so a vial can be entered more than once.
How it is made and tested
Renew Lab Group purifies, sterile-filters, fills and seals every vial in Houston, then tests each batch in our analytical lab: HPLC, endotoxin by the LAL method, pH and sterility. Outside clients can order the same tests; see HPLC Lab Testing Services.

Frequently Asked Questions
What is sterile water for injection?
Sterile water for injection (SWFI) is purified, sterilized water with no added preservative, salt or buffer. Renew Lab Group sells it in sealed vials for research use only.
What is the difference between sterile water and bacteriostatic water?
Sterile water has no preservative and is meant for single use. Bacteriostatic water contains 0.9% benzyl alcohol, which inhibits bacterial growth so a vial can be entered more than once. We sell both in 20 mL vials.
Can one vial be used more than once?
Single use is recommended. Because this water has no preservative, a punctured vial is not protected against microbial growth. Discard any unused portion according to your institution’s protocol.
Does it contain benzyl alcohol?
No. It is preservative-free (0% benzyl alcohol). If your protocol needs a preserved diluent for multi-draw vials, choose bacteriostatic water instead.
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 endotoxin, pH and sterility. It is not issued per shipment. For COA questions, call 936-379-5515 or email info@renewlabgroup.com.
How should I store sterile water for injection?
Store unopened vials at controlled room temperature, away from direct light. Do not use if the seal is broken or the liquid is cloudy or discolored.
