Our own laboratory, testing every batch.
Every batch that leaves Hanaoka goes through our own analysis laboratory before it reaches you.
From the bench to the released batch.
Batch-by-batch quality control
No batch leaves the plant without internal analysis, and purity comes from bench results.
PA/ACS grade testing
We verify that every product meets the required analytical specifications — from technical grade to PA-ACS, per American Chemical Society standards.
New product development
New formulations and concentrations are born here before reaching production, always starting from a customer's real need.
Continuous improvement
Products already in circulation continue to be monitored and refined.
Four decades of an in-house analysis and research laboratory, ensuring quality control of every batch — from developing new products to continuously improving the ones already in circulation.
Laboratory · Records and traceability
Where it came from, where it's going — always on record.
Every batch is traceable from the laboratory to delivery. That's what lets us answer, with data, any question about the origin and quality of a Hanaoka product.
