Crystallization of calcium oxalate was studied in minimally diluted (92%) urine using a mixed
suspension mixed product crystallizer in series with a Malvern particle sizer. The
crystallization was initiated by constant flow of aqueous sodium oxalate and urine into the
reaction vessel via two independent feed lines. Because the Malvern cell was in series with
the reaction vessel, noninvasive measurement of particle sizes could be effected. In
addition, aliquots of the mixed suspension were withdrawn and transferred to a Coulter …
