High-Purity H₂O₂ Solution for Analytical and Research Applications
The Hydrogen Peroxide 30% Unstabilised, AnalaR NORMAPUR® reagent from VWR Chemicals is a high-purity oxidising agent ideal for precise analytical procedures. Manufactured to AnalaR NORMAPUR® specifications, this unstabilised H₂O₂ solution delivers controlled reactivity, making it suitable for applications where stabilising additives may interfere with test results or sample integrity.
Key Features
- Concentration: 30–32% hydrogen peroxide (w/w)
- Unstabilised Formulation: Free from stabilisers that may affect sensitive reactions
- Analytical Grade: Meets AnalaR NORMAPUR® purity standards for laboratory use
- Low Impurity Profile: Minimal trace metals and low acid content for reliable results
- Wide Application Range: Suitable for oxidation, sample digestion, trace analysis, and synthesis
