Using < 0.1 NTU StablCal Solution
Bulk solution (bottles) or sealed sample cells (vials)
This solution may be substituted for low-turbidity water when performing a
calibration using StablCal Standards.
1. Never shake or invert* this solution. Do not generate any bubbles in the
solution. Allow the solution to sit undisturbed for several minutes before use.**
2. Carefully pour the solution down the inside wall of the sample cell; this prevents
any air bubbles from forming in the sample cell.
3. Immediately cap the sample cell and the bulk solution bottle.
4. Let the filled sample cell sit undisturbed for 2 – 3 minutes.
5. The sample cell containing the solution is now ready for measurement.
REPLACEMENT PARTS AND REAGENTS
StablCal Stabilized Formazin Turbidity Standards are available in sealed sample
cells (vials) or in bulk solution (bottles). The sealed sample cells are supplied in
Calibration Sets. The bulk solution is available in individual bottles or in Calibration
Sets.

* If the solution is shaken, it can take several hours for all the bubbles to dissipate; therefore
it is recommended to refill the sample cell with fresh, unshaken < 0.1 NTU StablCal Solution.
** If the < 0.1 NTU StablCal Solution (Cat. No. 26597) has been mixed recently, wait at least 10 – 15 minutes before using.
