Here at Hanna, we recommend to always clean an electrode after every testing to eliminate impurities and residue. Regular cleansing and proper care ensures the electrode is correctly maintained for maximum performance to achieve accurate readings, faster response times, and repeatability.
HI-7061L is a general purpose cleaning solution which can be used for a variety of applications. Electrodes become dirty from use and will produce inaccurate results even if they read correctly in a pH buffer. HANNA’s cleaning solutions eliminate impurities and residues which are left on electrode surfaces when immersed in samples during measurement or when stored incorrectly.
At HANNA, we suggest cleaning the bulb and junction of your electrode on a regular basis in our ready-to-use cleaning solutions to ensure that the probe is always clean and to prevent any clogging of the junction.
All cleaning solutions are packaged in an air tight bottle with tamper-proof seal to ensure quality and freshness. All solutions show a batch number and expiry date.
Available in 230ml and 500ml bottles, and individual 20ml sachets in packs of 25.
- After cleaning, rinse the electrode in tap water and then place in a HANNA Storage Solution before calibrating or taking measurements.
- Always follow up with a HANNA Buffer/calibrating Solution for the best results.
Which cleaning solution to use . . .?
Soak in Hanna General Cleaning Solution (HI-7061) for between 30 minutes and 1-and-a-half hours to dissolve mineral deposits and other general coatings. (Non-aggressive formula).
Soak in Hanna Protein Cleaning Solution (HI-7073) for 15 minutes to enzymatically dissolve deposits from protein sources.
Soak in Hanna Inorganic Cleaning Solution for 5 to 15 minutes. This cleaner is especially effective at removal of precipitates caused by possible reactions - Usually used in industrial applications.
Oil and grease removal requires the correct chemicals to dissolve the coating, but mild enough to leave the electrode unaffected. Use Fat Cleaning Solution for effective cleaning after each measurement, followed by flushing with tap water.
If you are a cheese maker, for instance, we have a specialised cleaning solution for all your electrodes.
Choose from the list below for your application. Most of the product codes below are for the 20ml x 25 sachets which are a great way to ensure your solution is always fresh, but do check with us before ordering if you require a greater quantity. For instance, your application’s cleaning solution may be available in a 500ml or 230ml bottle.
