Quanti-Tray® Sealer Check Policy (NC WW/GW LCB 01/28/2022)
If the Quanti-Tray® or Quanti-Tray®/2000 test is used, the sealer must be checked monthly by adding a dye (e.g., food color or bromocresol purple) to a water blank. If dye is observed outside the wells, either perform maintenance or use another sealer.
