Our Wastewater Standards Are Convenient & Easy-To-Use
Some unique wastewater product concepts include:
- Pre-measured, single-use reference materials that prevent laboratory errors and re-work.
- Ready-to-use CRMs requiring no preparatory steps to save time and effort.
- Cocktailed, multi-parameter CRMs that can be used for numerous types of testing procedures. Thus, reducing the number of CRMs needed in the typical laboratory.
