The majority of cleaning solutions we offer are for the cleaning of the sensitive glass pH sensor. Other cleaning solutions photometric measurements and include the cuvette cleaning solution used to the clean the cuvettes used in turbidity meters, spectrophotometers, photometers, and the Checker HC colorimeters. Also available is a cleaning solution for the suction lysimeter used to extract liquid from soil for photometric analysis.
The fundamental use of calibration and cleaning solutions is to correctly maintain electrode operation to assure accurate and reproducible readings. The most common cause for pH measurement inaccuracies is an unclean or improperly cleaned electrode. This is very important to note, because during calibration, the instrument assumes that the electrode is clean and that the standardization curve created during the calibration process will remain a valid reference until the next calibration. pH meters on the market today will allow an offset voltage of approximately ±60 mV. The deviation from 0 mV is not unusual but ideally should be no greater than ±30 mV. The calibration process compensates for the change in offset voltage.
Electrodes can become dirty from use and will produce inaccurate results even as they read correctly in a pH buffer. Hanna’s cleaning solutions eliminate impurities and residues that are left on electrode surfaces when immersed in samples during measurement and stored incorrectly. Hanna suggests cleaning the bulb and junction of your electrode on a regular basis to ensure that the probe is always clean and prevent any clogging of the junction.
Hanna offers a wide variety of cleaning solution from general purpose, protein cleaning, inorganics, and oil and grease to ones that are intended for specific applications such as wine, dairy and soil to name just a few.
Hanna cleaning solutions:
The cuvette cleaning solution is used to clean the haze that can form on the glass and interfere with the transmission of light through the cuvette. Also available is the cleaning solution used with the suction lysimeter for extracting liquid from soil for photometric analysis
