Abstract
A fluorimeter has a flash lamp, a measurement station with a receiver for microtitration plates, at least one measurement head disposed at the receiver and an evaluation station having a detector. Emission signals given off by a sample are evaluated by the detector. Light guides extend from the flash lamp to the measurement head from the measurement head to the detector. At the measurement station one measurement head is arranged above a sample and one measurement head beneath the sample. A change-over switch is formed by a pivotal bar which connects the light guides selectively to the upper or the lower measurement heads. On the pivotal bar are connections for the light guides which lead to the upper and the lower measurement heads. Connection of a respective measurement head can be brought selectively into correlation with the light source and the detector.
