Achieve Confidence in Microbiology Testing

NSI is a globally trusted brand for laboratory quality control standards and proficiency tests. Use of Certified Reference Materials (CRMs) and Proficiency Tests (PT) Standards on a routine basis to monitor analytical performance will defensibly document data quality and support accreditation requirements.

Proficiency Testing for Quantitative and Qualitative Test Performance

PT samples have to be right. Your laboratory's accreditation is at stake, so anything less than 100% confidence is just not good enough. That's why we are proud to offer NSI ISO-17034 accredited proficiency testing for Environmental, Food Science, and Cannabis labs. Scheduled PT are available throughout the year.

Environmental Wastewater Standards

NSI has the standards to support your wastewater testing with full confidence. Unique product concepts include pre-measured, single-use reference materials that prevent laboratory errors and ready-to-use CRMs requiring no preparatory steps to save time and effort.
