View brandDetailed compound information
Sterile water for injection (SWFI) is preservative-free, non-pyrogenic water intended as a single-use diluent. Unlike bacteriostatic water, SWFI contains no benzyl alcohol — making it the appropriate choice for research protocols where benzyl alcohol cross-reactivity, single-dose requirements, or neonatal/sensitive-tissue models would contraindicate the standard bacteriostatic diluent.

Reference material & peer-reviewed citations
Research peptides are chemical reagents for laboratory analysis. Regulations vary by jurisdiction — it is the buyer's responsibility to ensure compliance with local laws. See our Terms & Conditions page for the full regulatory framework across the EU, UK, US, Switzerland, Thailand, and other major markets.
Lyophilized (unreconstituted) peptides should be stored at -20°C for long-term storage or 2-8°C (refrigerated) for short-term use. Once reconstituted with bacteriostatic water, store at 2-8°C and use within 30 days. Avoid repeated freeze-thaw cycles — aliquot into smaller portions if needed.
Ready to use. Withdraw the full volume through a sterile filter needle for single-use reconstitution. Add slowly along the interior wall of the target vial; swirl gently. Discard any unused portion — SWFI offers no antimicrobial protection.
Gently inject bacteriostatic water (bacteriostatic water) along the inside wall of the vial — do not spray directly onto the powder. Let it dissolve naturally or gently swirl. Never shake vigorously. Standard reconstitution: add the desired volume of bacteriostatic water based on your concentration needs. For example, 5mg peptide + 2.5ml bacteriostatic water = 2mg/ml concentration.
