Powerful Mixing and Homogenization
An important advantage of the Phoenix DB-6 is the speed with which the receptor cell’s contents are homogenized. A critical factor in diffusion cell testing for IVRT and IVPT applications is the uniformity of the receptor media. Any unmixed, high concentration of API dwelling directly under the membrane will slow the diffusion process, affecting test results. The Phoenix system resolves this issue through custom-designed mixer-inserts inside each cell, driven by powerful brushless motors. The combination of grooved mixers and strong magnetic drives prevents the formation of diffusion-rate barriers directly under the membrane, thereby reducing variability of test results. Stirring speeds are programmable from 200 rpm to 900 rpm with an accuracy ± 10%.
