Bacteriostatic Water
3ml · 10ml
Price range: $10.00 through $13.00Select options This product has multiple variants. The options may be chosen on the product page
Sterile water with 0.9% benzyl alcohol as a preservative, which is what allows a reconstituted vial to be stored and drawn from over weeks rather than discarded after a single use. Not included with compounds; add it to any order. Ships from Canada. Research use only.
Bacteriostatic Water
Sterile water with 0.9% benzyl alcohol. The preservative is the point: it inhibits bacterial growth, which is what permits repeated draws from a reconstituted vial over several weeks. Sterile water has no preservative and a much shorter usable life. 3ml / 10ml. → Buy Bacteriostatic Water Canada
Frequently Asked Questions
Why bacteriostatic water rather than sterile water?
The 0.9% benzyl alcohol. It inhibits bacterial growth, which is what allows a reconstituted vial to be stored and drawn from repeatedly over several weeks. Sterile water works, but with no preservative the vial has a very short usable life — suitable for single-use preparation only.
Is bacteriostatic water included with compounds?
No. Compounds ship as lyophilized powder and require reconstitution. Bacteriostatic water is sold separately in 3ml and 10ml vials — add it to any order.
How much do I need?
It depends on the concentration you’re working toward, and that’s a choice rather than a fixed rule. More diluent means a more dilute solution and a larger, more easily measured draw volume. Less means a more concentrated solution. The free Peptide Reconstitution & Dosage Calculator does the arithmetic for any combination.
Does every compound dissolve in bacteriostatic water?
Most do, but not all. 5-Amino-1MQ is a small molecule rather than a peptide and requires DMSO or ethanol — bacteriostatic water will not dissolve it. Solubility is listed on every product page.
