Other Notes

Los valores de pH de todas las disoluciones tampón son dependientes de la temperatura y la concentración. En el caso de los tampones Tris, el pH aumenta alrededor de 0,03 unidades por cada °C de disminución de la temperatura, y disminuye 0,03-0,05 unidades al ser diluido por 10. Para aplicaciones precisas, debe utilizarse un peachímetro cuidadosamente calibrado con un electrodo de vidrio/calomelano combinados.
