Saturation is the point at which a solution of a substance can’t dissolve more of that substance. The saturation point of some biological buffers, such as ACES, is quite low; others, like HEPPS, get saturated at much higher concentrations.

In this post we present a chart with the saturated concentrations of Hopax Fine Chemicals’ biological buffers in solution at 0°C.
