Calibration Solution Stock concentrate
This is a concentrated 10x version of the standard solution 3 of the 3 point calibration solution, or 2 point calibration solution (for the CG200 or single meter options).
This requires careful dilution steps to make working solutions. We advise using a weigh scales rather than volumetric flasks, 1g of water = 1ml. so a 10 x dilution would require weighing 100mls (100g) of stock and adding it to 900mls (900g) of DI water.

1L and 5L options are available
Shipping prices will increase by weight
