Sterile Water for Injection
Sterile water for injection — universal neutral-pH diluent for reconstitution.
Overview
Sterile Water for Injection (SWFI) is pyrogen-free, sterile-filtered water manufactured to USP/EP pharmaceutical standards for parenteral preparation use in laboratory settings. It is supplied in sealed, single-use pharmaceutical-grade vials with no preservatives or additives.
As a universal, pH-neutral diluent (pH 5.5–7.0), SWFI is the preferred reconstitution vehicle for lyophilized peptides that exhibit good solubility across neutral pH ranges, including many hormones (oxytocin, HCG), neuropeptides (VIP, KissPeptin-10), and stability-neutral research compounds. It is also used for serial dilution of reconstituted peptide stock solutions in laboratory protocols.
Handling & storage
Laboratory diluent for reconstituting lyophilized peptides. Store as labeled and keep sealed; draw with sterile technique. Match the diluent and volume to the peptide and your target concentration.
