BACTERIOSTATIC WATER Bacteriostatic Water is a sterile, non-pyrogenic aqueous solution containing 0.9% benzyl alcohol, designed for use in research environments requiring controlled reconstitution and dilution of lyophilized compounds. The inclusion of benzyl alcohol inhibits bacterial growth, allowing for multiple withdrawals under proper sterile laboratory conditions.

OVERVIEW
Bacteriostatic water (BAC water) is sterile water containing 0.9% benzyl alcohol as a preservative. It inhibits bacterial growth, making it the gold standard for reconstituting lyophilized peptides in research settings.
The 0.9% benzyl alcohol prevents microbial contamination, allowing multi-dose use over 28 days — unlike sterile water which must be discarded after a single use.
Formulated to maintain peptide stability during and after reconstitution. The low preservative concentration won't denature sensitive research compounds.
Manufactured under strict GMP conditions and meets USP standards for purity, sterility, and endotoxin levels.

FAQ
Bacteriostatic water contains 0.9% benzyl alcohol preservative, allowing multi-dose use for 28 days. Sterile water has no preservative and must be used immediately — any remaining must be discarded.
·Essential accessory for peptide research
·Benzyl alcohol prevents bacterial contamination
·Do not use if solution appears cloudy or discolored
·Not for direct injection — used for reconstitution only
STEP-BY-STEP GUIDE
You'll need: bacteriostatic water vial, peptide vial, alcohol swabs, and an appropriate syringe with needle.
Tip: Use insulin syringes (1mL) for precise measurement.
Wipe the rubber stoppers of both the BAC water vial and the peptide vial with alcohol swabs. Allow to air dry for 10 seconds.
Never skip sanitization — contamination ruins peptides.
Insert the syringe needle into the BAC water vial and draw the desired amount. Common volumes: 1mL or 2mL per peptide vial.
Tip: Pull back the plunger slowly to avoid air bubbles.
Insert the needle into the peptide vial and gently release the water against the inside wall of the vial. Do NOT inject directly onto the powder.
Never shake the vial. Agitation can denature the peptide.
Let the vial sit for 1-2 minutes. The peptide should dissolve on its own. If needed, gently roll the vial between your palms.
Tip: Solution should be clear. If cloudy or particulate, do not use.
Once reconstituted, store the peptide vial in the refrigerator at 2-8°C (36-46°F). Use within 28 days of reconstitution.
Never freeze reconstituted peptides.
TECHNICAL
STORAGE & HANDLING
15-30°C (59-86°F)
Store unopened at controlled room temperature. No refrigeration required until after reconstitution with peptides.
Protect from light
Keep vials in original packaging or dark storage area.
Until expiration date
Unopened vials stable until printed expiration. Once punctured, use within 28 days.
28 days maximum
Mark the date on vial after first puncture. Discard after 28 days regardless of appearance.
Preferred over sterile water for multi-dose protocols
