Environmental Certified Reference Materials and Proficiency Test Standards

Our wastewater standards enhance your testing accuracy and efficiency. Regular use of our certified reference materials (CRMs) and proficiency test (PT) standards ensures high data quality and supports accreditation needs.

We specialize in ISO-accredited CRMs and effluent standards that are stable and integrate seamlessly into routine workflows. Pre-measured, single-use materials help prevent errors and simplify processes. For example, try our GGA Concentrate Snips™: just snip and pour into a 300 mL BOD bottle—no measurements or contamination. Our versatile, multiparameter CRMs streamline testing procedures, reducing the need for multiple CRMs in your lab. Watch the demonstration video to learn more!
