Frequently Asked Questions
Q: Why is light-resistant amber packaging required for Potassium Permanganate?
A: Potassium Permanganate is sensitive to photolytic decomposition, which can reduce it to manganese dioxide ($MnO_2$). Amber packaging protects the reagent’s purity during long-term storage.
Q: Can government and university research labs procure this reagent via GST invoice & GeM?
A: Yes, Apex Labs provides full GST tax invoices for ITC claiming and fulfills orders for institutions via direct contracting and rate contracts on the Government e-Marketplace (GeM) portal.
