quality, inexpensive laboratory
and industrial processing pH, ORP (Redox), Ion-Selective electrode (ISE)
Headquarters. |
| All Ion-Selective
Electrode (ISE) calibration standards are made from
high-purity deionized water and ACS reagent chemicals.
The chemicals are dried in the oven according standard
analytical procedures and weigh by analytical balance to
4th decimal point (0.1 mg), dissolved in a grade "A"
flask.
