Stabilised Formazine Primary Standard Solution for turbidity meter verification.
Stablcal Turbidity Standard is required for fast and reliable verification of the turbidimeter. The standard is packaged in 100 mL bottle. Ready-to-use Standard Solution has the concentration of 200 NTU. The solution is compatible with TL23, TU52, 2100Q, 2100N and 2100AN series turbidity meters.
Procedure for frequently used StablCal Turbidity Standards
This process applies to standards that are used daily or weekly.
For bulk solution standards: Invert the content of the bottle 10 times. Oil and index the sample cell to remove any optical deviations on the sample cell. Invert a few times before adding the standard into the sample cell. Use the bulk standard solution to rinse the sample cell. Fill and close the sample cell.
For bulk solution and sample cell standards: In addition to the aforementioned procedure, leave the sample cell for a few minutes. The sample cell is now ready for the analysis.
Storage conditions
It is recommended to store solutions at the temperature from 5 °C to 25 °C. It is required to refrigerate the standard at the temperature of 5 ˚C for long-term storage.
