Professional Service Laboratory
It was the first test laboratory of a public university to be nationally accredited before the Mexican Accreditation Entity.
It holds the following accreditations:
Wastewater, AG-051-008/10, Physicochemical, A-064-009/10, Waste,
R-0150-50-015/10
It offers services on analytical chemistry, simple or specialized physicochemical and technologic development for companies. The NOM 17025 accreditation allows us to perform: Natural water analysis, treated wastewater, sampling, CRIT tests analyses, and chemical analyses. We also perform the following general analyses for: minerals, ferrous and non-ferrous alloys, oils, diesel, wastewater, solid waste, solvents, reagents, physicochemical analyses, and analytical methodology development.
