Protein Cleaning pH Electrode Solution, 500ml - 

HI-7073L is a protein cleaning solution with enzymatic properties specially formulated for use in applications where a pH electrode can be coated with proteins. 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. 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.
