Hanaoka's line of analytical-grade chemical reagents (PA and PA-ACS) — developed specifically for analysis, quality control and research laboratories that demand reliability, traceability and technical excellence. For larger-scale industrial use, see our Solutions by segment.
The result of more than 40 years of Hanaoka's know-how in manufacturing, handling and controlling chemical products, PureLab was created to concentrate all that knowledge into a line dedicated to high-standard reagents — our own manufacturing, start to finish.
Own manufacturing · Cotia, SP
From manufacturing to certificate, in Cotia.
Every PureLab reagent goes through its own purification process and analytical control by ICP-OES in our laboratory, before being released with a certificate of analysis per batch.
Start with the four most sought after.
Nitric Acid PA 65%
PA 65% grade, with a certificate of analysis per batch.
See specifications →Sulfuric Acid PA-ACS
American Chemical Society standard.
See specifications →Hydrochloric Acid PA-ACS
High purity for analysis and process control.
See full specifications →Ethyl Ether PA-ACS
Extraction and synthesis solvent, analytical grade.
See specifications →All reagents in the PureLab line.
27 PA and PA-ACS grade reagents, from acids to solvents — each with its own manufacturing and control, for laboratory use.
Filters by name, chemical formula (e.g., H₂SO₄) or CAS number (e.g., 7664-93-9).
