Volumetric Solutions

All volumetric solutions are marked with the lot number of their production batch, and with the concentration factor of the respective batch. All our volumetric solutions are NIST traceable. All volumetric solutions are sold in 1 litre PE bottles, with caps sealed with a PE foam liner.

Concentrations are given in mol-equivalents per litre, prices are Canadian dollars. All volumetric solutions are produced by the Avalon Institute, and are products “Made in Canada.”

If you require a volumetric solution not in the below lists, please enquire whether it is available through a customized order.

Auxiliary substances are often required in complexometric titration, for example ammonia – ammonium chloride buffer (“hardness buffer”) for the titration of Ca, Mg, and water hardness. Auxiliary substances that are liquid are sold in 250 ml PE bottles. Those that are solids, are in 100 g bottles.

Disodium Tartrate Auxiliary complex 100 g $18.00
Hardness Buffer Water hardness titration 250 ml $16.00
iso-Ascorbic Acid Fe and Mn reduction 100 g $18.00
Michaelis Buffer Various metal titrations 250 ml $16.00
