MPN Calculator for IDEXX Quanti-Tray®/2000
With our software, MPN Calculator 3.1, labratory researchers and water quality professionals can simplify the process of finding the MPN/100ml. IDEXX provides a two- page table for this purpose, but our software makes this much easier.
At PUR we test, among other water quality parameters, the amount of coliform and E. coli in water samples. To do this, the IDEXX Quanti-Tray®/2000 is filled with a water sample which has been mixed with chemicals providing the bacteria with food and an indicator. After incubating for 24 hours we determine the amount of coliform bacteria present by how many wells, in the tray, turn yellow. The amount of E. colipresent is determined by counting the cells that glow under a black light. You can see these glowing cells in the photo.
The MPN Calculator is also available as an online tool! Because of PUR's partnership with Oregon State University, the MPN Calculator is now available as an online tool, with no need for download.
