Mettler Toledo™ Thiourea Cleaning Solution
Removes silver sulfide contamination from pH electrodes. Mettler Toledo™ Thiourea Cleaning Solution helps maintain electrode performance and should be utilized after measurements and prior to recalibration. Treatment should be applied until discoloration.
Brand: Mettler Toledo™ 51350102
Description
The pH electrode is the main actor of pH measurement. It requires special care and attention. The removal of contamination is required before the electrode can be re-calibrated and used for another measurement. Rinsing with deionized water is not sufficient when silver sulfide contamination is present; Thiourea is recommended in this case.
- Available in a handy screw-cap bottle with a no-fuss label
- SDS and label contain information according to GHS (Globally Harmonized System)
- Treatment time is approximately 1 hour
