Description
Reconstitution Water (Bacteriostatic Water for Injection, USP) is sterile water containing 0.9% benzyl alcohol as a bacteriostatic preservative. It is the standard diluent used for reconstituting lyophilized (freeze-dried) peptides, hormones, and other injectable products throughout this catalog. Bacteriostatic water differs from Sterile Water for Injection (SWFI) in one critical respect: the benzyl alcohol preservative inhibits the growth of most bacteria that might be introduced during repeated needle entries into a multi-dose vial. SWFI lacks this preservative and must be used immediately after opening (single-use), while bacteriostatic water can be used for up to 28 days after first puncture when stored properly.
The 0.9% benzyl alcohol concentration is the standard USP concentration — sufficient to prevent microbial growth but low enough to avoid tissue toxicity at the injection volumes used with peptides. When reconstituting lyophilized peptides, the bacteriostatic water is slowly injected down the side of the vial (not directly onto the peptide cake) and the vial is gently swirled (never shaken) to dissolve the powder. The reconstituted solution should be clear and free of particulates before use.
Clinical Context
Bacteriostatic water is an essential supply item that accompanies nearly every lyophilized product in this catalog. The two vial sizes serve different needs: the 3ml vial ($7.03) is sufficient for reconstituting 1–2 peptide vials at standard concentrations, while the 10ml vial ($9.82) is more economical for reconstituting multiple products. Proper reconstitution technique is essential for maintaining peptide stability and sterility — improper technique (shaking, contamination, wrong volume) can denature peptides or introduce bacterial contamination.
- CONTAINS BENZYL ALCOHOL (0.9%) — contraindicated in neonates and infants (benzyl alcohol toxicity/"gasping syndrome"); use Sterile Water for Injection (SWFI) instead for pediatric patients
- 28-day beyond-use date after first needle puncture — discard after 28 days regardless of remaining volume
- Do not freeze — freezing and thawing can compromise sterility
- Always use aseptic technique when drawing from the vial — swab the stopper with alcohol before each needle entry
- When reconstituting peptides: inject water slowly down the side of the vial, never directly onto the lyophilized cake; swirl gently, never shake
- The 10ml vial ($9.82) is significantly more cost-effective than the 3ml vial ($7.03) for multi-product reconstitution
- Reconstituted peptide solutions should be refrigerated (2-8°C) and used within the peptide manufacturer's recommended timeframe (typically 2-4 weeks)
- Visual inspection: the reconstituted solution should be clear, colorless, and free of visible particulates — discard if cloudy, discolored, or particulate
