AbstractAn automated collagen solubilizing apparatus that maintains constant electrolytic conditions during solubilization is described. It was used in solubilization of 6.95 of a calfskin corium as monomeric collagen in citrate buffer at pH 3.44 and ionic strength of 0.44 and a temperature of 8°C. It is shown that this is the limit of solubilization for undenatured collagen in this buffer
