Bacteriostatic Water 30ml – 1 Pack

Bacteriostatic Water 30ml – 1 Pack from Renew Lab Group is a single sterile 30ml multi-dose vial of pharmaceutical-grade bacteriostatic water, preserved with 0.9% benzyl alcohol to support repeated, sterile reconstitution of lyophilized research compounds. Every batch is manufactured in our Houston, TX cleanroom and verified by third-party HPLC testing, and each order ships with a Certificate of Analysis so your lab can confirm purity and concentration before use.

✓ USP Grade ✓ HPLC Verified ✓ 0.9% Benzyl Alcohol ✓ COA Included ✓ Endotoxin <0.1 EU/mL ✓ Houston Made

Pharmaceutical-grade bacteriostatic water in a 30ml sterile multi-dose vial — 1 vial per order. Preserved with 0.9% benzyl alcohol (HPLC-verified) for repeated sterile access. Manufactured in our Houston, TX cleanroom under USP Bacteriostatic Water for Injection monograph specifications. Every order ships with the batch Certificate of Analysis.

Why Researchers Choose Renew Lab Group Bacteriostatic Water

Renew Lab Group manufactures bacteriostatic water specifically for laboratory and research applications, not as a generic mass-market product. Each batch is produced in an ISO-classified cleanroom under procedures aligned with the USP Bacteriostatic Water for Injection monograph, then verified with HPLC testing to confirm benzyl alcohol concentration and screened for endotoxin and microbial growth before release. Rather than relying on manufacturer averages, we ship every order with a batch-specific Certificate of Analysis, so your team has documented traceability for internal quality records. The larger 30ml fill reduces the number of vials your lab needs to stock for higher-volume research protocols, which is why compounding pharmacies, peptide researchers, and university labs choose Renew Lab Group as their bacteriostatic water supplier.

Reconstitution Guidance for Research Use

When reconstituting lyophilized peptides or other research compounds with this 30ml vial, allow it to reach room temperature before use, wipe the rubber stopper with an alcohol swab, and insert the needle at a slight angle so the water runs gently along the vial wall rather than directly onto the lyophilized material. Swirl gently rather than shaking to avoid stressing sensitive compounds. Because this bacteriostatic water contains 0.9% benzyl alcohol as a preservative, an opened multi-dose vial can generally be used for repeated draws over its stated shelf life when stored correctly, which reduces waste for ongoing research protocols. This product is intended strictly for laboratory and research use and is not evaluated or approved for human or veterinary administration.

Frequently Asked Questions

What is bacteriostatic water used for?
Bacteriostatic water is used to dissolve (reconstitute) lyophilized research peptides, hormones, and other compounds into solution. The 0.9% benzyl alcohol preservative maintains vial sterility through multiple draws over up to 28 days when refrigerated.

How should I store this product?
Store unopened vials at room temperature, away from direct light. After first use, refrigerate at 2–8°C and use within 28 days. Discard if the solution appears cloudy or discolored.

Is a Certificate of Analysis included?
Yes. Every order from Renew Lab Group includes the batch-specific COA documenting benzyl alcohol concentration (HPLC), pH, endotoxin (<0.1 EU/mL), and sterility (PASS).

Is this product USP grade?
Yes. Our bacteriostatic water meets USP Bacteriostatic Water for Injection monograph specifications, including benzyl alcohol concentration, pH, endotoxin, and sterility requirements.

How many draws can I get from one 30ml vial?
Because this is a multi-dose vial preserved with 0.9% benzyl alcohol, researchers can generally draw from the same vial multiple times across its usable shelf life rather than opening a fresh vial each time. The exact number of draws depends on your protocol’s volume per reconstitution — always follow your lab’s own procedures and discard the vial if the solution becomes cloudy or discolored.

Should I order the 1-Pack or a multi-pack?
The 1-Pack is a good fit if you only need bacteriostatic water occasionally or want to try our product before committing to a larger order. If your lab reconstitutes regularly, our 2-Pack, 5-Pack, and 10-Pack options reduce the cost per vial and cut down on reorder frequency. All pack sizes use the identical USP-grade 30ml formulation.
