Sterile Water for Injection

Purity: ≥99% HPLC
Format: Lyophilized powder
Quantity: 3 ml per vial
SKU: WA3

Product 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.

Research Applications

Sterile Water for Injection has been examined in experimental studies related to:

• Universal peptide reconstitution and dilution protocols
• pH-neutral reconstitution vehicle for soluble peptides
• Comparison of reconstitution vehicles (SWFI vs acetic acid water vs bacteriostatic water)
• Pharmaceutical-grade laboratory diluent preparation
• Lyophilized peptide stock solution serial dilution research
• Parenteral solution preparation standards in research settings
