To use, simply snip open the tube and pour contents directly into a 300mL BOD bottle. No measurements are required and no contamination is possible. Watch the video below for a full product demonstration!

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.
