Bacteriostatic Water 10ml – 2 Pack

Bacteriostatic Water 10ml – 2 Pack from Renew Lab Group includes two sterile 10ml multi-dose vials of pharmaceutical-grade bacteriostatic water, each 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 10ml sterile multi-dose vials — 2 vials 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 its 10ml bacteriostatic water specifically for labs that run small, frequent reconstitutions and want to minimize waste between batches. Each lot is produced in an ISO-classified cleanroom in Houston, Texas, under procedures aligned with the USP Bacteriostatic Water for Injection monograph, then verified by HPLC testing to confirm the 0.9% benzyl alcohol concentration and screened for endotoxin and microbial growth before release. Instead of relying on generic manufacturer averages, every order ships with a batch-specific Certificate of Analysis so your lab has documented traceability on file. Having two vials on hand means your lab always has a backup ready without waiting on a reorder.

Reconstitution Guidance for Research Use

When reconstituting lyophilized peptides or other research compounds with these 10ml vials, let each vial reach room temperature first, wipe the rubber stopper with an alcohol swab, and direct the needle along the interior wall of the vial rather than straight onto the lyophilized powder, which helps it dissolve evenly. Swirl the vial gently rather than shaking it, since vigorous agitation can stress sensitive compounds. Because the water is preserved with 0.9% benzyl alcohol, an opened 10ml vial can generally support multiple draws over its usable shelf life rather than requiring a new vial every time, which suits labs running smaller, frequent reconstitutions. This product is intended strictly for laboratory and research use and has not been 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 this 2-Pack?
Each of the two 10ml vials in this pack is a multi-dose vial preserved with 0.9% benzyl alcohol, so researchers can typically draw from each vial multiple times across its usable shelf life rather than requiring a fresh vial per use. The exact number of draws depends on your protocol’s volume per reconstitution — always follow your lab’s own procedures and discard any vial if the solution becomes cloudy or discolored.

Should I order the 2-Pack or a different pack size?
The 2-Pack is a good middle ground if you want a backup vial on hand without committing to bulk quantities. If your lab uses bacteriostatic water only occasionally, our 1-Pack may be a better fit; if you reconstitute frequently, the 5-Pack and 10-Pack offer a lower cost per vial. All pack sizes use the identical USP-grade 10ml formulation.
