This electronic reader makes hematocrit determinations easy and features a bright, large display. After hematocrit centrifugation is completed, simply transfer the RH12 rotor from the StatSpin centrifuge to the digital reader, set tube interfaces in three easy steps, then read the hematocrit value directly on the digital display. The reader features fiber-optic illumination, an easy-to-use sliding pointer and membrane set switch and includes a tube adapter for longer tubes.
