There is disclosed a closure mechanism for two reagent bottles in a bottle holder of an analyzer, using a shutter that slideably and frictionally engages the top surface of grommets at the mouth of the bottles. The shutter slides to either an open or closed position of the bottles, either both in lock-step or with one bottle open, the other closed, and both closed together. The shutter is driven by a cam and cam followers, either rotationally or linearly.
