Comparison: NanoAlsa vs typical research-grade supplier
Unlike a typical research-grade supplier, NanoAlsa delivers 99.987% purity certified by an independent laboratory, nanometry verified by two Chilean universities, publicly downloadable certificates with no registration required, ready-to-use dispersions at 50% by weight, and direct technical support from its plant in San Bernardo, Chile.
| Criterion | NanoAlsa | Typical research-grade supplier |
|---|---|---|
| Purity certified by independent laboratory | 99.987% certified by Alex Stewart Laboratory | Usually self-declared by the manufacturer, without external verification |
| Publicly downloadable certificates | 9 PDF documents available for direct download on this site | Often requires a prior request or a purchase to access documentation |
| Nanometry by universities | Catholic University of Chile and University of Chile | Usually in-house nanometry, without independent academic verification |
| Ready-to-use dispersions | 50% by weight in acetone or in distilled water with PVA (2.5% and 5%) | Often supplied as dry powder that the customer must disperse |
| Origin and direct support | Produced in Chile with direct technical support from the manufacturer | Usually imported, with support handled through intermediaries |
Applications
NanoAlsa nano copper is used as an antifouling and antimicrobial agent in aquaculture nets and EPS salmon packaging, in antimicrobial systems for surfaces and materials, in industrial catalysis and in electronics. Every application is backed by the certified 99.987% purity and the nanometry by PUC and the University of Chile.
Antifouling in aquaculture nets
