Bacteriostatic water 30mL is supplied as lyophilized powder under nitrogen. Typical reconstitution is in sterile or bacteriostatic water; the exact concentration depends on your protocol. Our free reconstitution calculator computes mL per dose and insulin-syringe units from any combination of vial size, water volume, and target dose.

Batch BW-2607 of Bacteriostatic water 30mL is verified at USP HPLC main-peak purity, with confirmation of molecular weight by LC-MS and endotoxin screening by LAL assay. One vial of every batch is also shipped to an independent US-based third-party lab for blinded re-verification. The full COA — including the chromatogram, mass spec trace, and third-party report — is bundled with your order as a downloadable PDF.
