Phosphate standard solution to be used in conjunction with the 3292 Phosphate Electrode and QP459 Ion Meter.

All of our stock standards are 1000ppm and are supplied in 500ml leak proof bottles.

All glassware should be clean. If glassware has been washed in tap water or in a glassware washing machine  it will need to be rinsed in deionised water prior to use. Residual water causes unwanted dilution so thoroughly dry glassware prior to use.

Be careful to avoid touching the insides of glassware or containers which are used for measurement if possible. The most common contaminants are Sodium and Chloride from sweat and in some applications this may not be desirable.
