HI-70636L Cleaning Solution for Wine Stains (500ml)

The HI-70636L is a highly-effective cleaning solution, specially formulated for use with pH electrodes stained with wine juice and must deposits. Measuring the pH in wine is a critical, indeed the most important step in ensuring the very best quality of the final product.

pH affects everything from fermentation to microbial stability and taste. Improper pH measurement can mean readings are up to a 0.5 pH unit off. This variability risks spoilage and other serious quality issues.

*An ebook on The Essential Guide to Measuring pH in Wine will be available very shortly. Visit us again for updates.

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 500ml bottles, and individual 20ml sachets in packs of 25.

Useful tips:

Which cleaning solution to use . . .?

Soak in HANNA General Cleaning Solution (HI7061) 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 (HI-7074) 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 require the correct chemicals to dissolve the coating, but mild enough to leave the electrode unaffected. Use HANNA HI-7007 or HI-8077 Oil and Fat Cleaning Solution for effective cleaning after each measurement, followed by flushing with tap water.
