Figure 1. Setup of the set screw homogenization technique. The upper row of panels depicts the relative sizes of the set screw alone
(A), the set screw compared to an adult mouse eye (B), and a 1.5 ml tube containing a screw set and an adult mouse eye (sample). The lower row of panels depicts the vortex mixer
and the adaptor alone (D), with two samples not running (E), and with two samples running (F). Note the orientation of the sample tube in the vortex mixer adaptor. The lid of the 1.5 ml tube should face the center
of the adaptor to ensure that the sample remains in the adaptor.
