Our wastewater standards enhance your testing accuracy and efficiency. Regularly using our certified reference materials (CRMs) and proficiency test (PT) standards ensures high data quality and meets accreditation needs. We specialize in ISO-accredited CRMs and effluent standards for wastewater that are stable and seamlessly integrate into routine workflows. Our pre-measured, single-use materials prevent errors and simplify processes. For instance, try our GGA Concentrate Snips™: just snip and pour into a 300mL BOD bottle — no measurements or contamination. Our versatile, multiparameter CRMs streamline testing procedures, reducing the need for multiple CRMs in your lab. Watch our demonstration video to learn more!
