For laboratories without a permanent purification system — or as a reliable backup beside your PromQ Prime — PromQ Water delivers HPLC & spectroscopy grade water in inert glass packaging, with the same purity guarantees as our purification systems.
Every bottle is filtered through a 0.22 µm membrane, sealed under sanitised conditions and shipped with a Certificate of Analysis quoting the production batch — perfect for regulated environments where traceability is non-negotiable.
Convenience that doesn't compromise.
HPLC & Spectroscopy Grade
Validated for the most sensitive analytical workflows — chromatography, spectroscopy and reagent dilution.
Lot Traceable
Each bottle ships with a Certificate of Analysis tied to its production batch for full regulatory traceability.
Inert Glass Packaging
Borosilicate glass with sealed cap — no plastic leachables, no contamination, long shelf life.
0.22 µm Filtered
Final filtration through 0.22 µm membrane removes bacteria and particulates before bottling.
