Sample vessel carrier for analytical centrifuge - stroboscopic illumination allows progress of centrifugation to be observed

摘要

Test tube holder is made in transparent plastic and mounted by a hinge on the end of the centrifuge arm. In the centrifuge lid is a window and below this a stroboscopic lamp, the frequency of which is linked to the centrifuge velocity. Photoelectric cells placed over different ends of the test tubes are used to detect the onset of clarification. and sedimentation and for timing the operation.
