2660242 Stablcal Stabilised Formazine Turbidity Standard 100 NTU, 100 mL

Stablcal Stabilised Formazine Turbidity Standard is required to conduct turbidimeter calibration. The capacity of the solution is 100 mL. Stablcal Turbidity Standard (p/n 2660242) is compatible with TL23, TU52, 2100Q, 2100N, 2100AN series turbidimeter. The solution is intended only for in-lab and field analysis.

Procedure for frequently used StablCal Turbidity Standards

This procedure is applied to the daily or weekly used standards.

For bulk solution standards: Invert the standard 10 times. Eliminate any optical deviations on the sample cell. Invert several times before adding the standard into the sample cell and rinse the sample cell at least once with the bulk standard solution. Fill and close the sample cell.

For bulk solution and sample cell standards: In addition to the aforementioned procedure, allow the sample cell to settle down for a few minutes. The sample cell containing the standard is ready for the analysis.

Storage conditions

Store standards at the temperature from 5 °C to 25 °C. Protect the solution from light rays. Allow the standard to acclimate to ambient instrument temperature before use.
