Fluorimeter
First Claim
1. A fluorimeter for measuring photoluminescence of a sample, said fluorimeter comprising:
- a measurement station including a receiver for receipt of a sample, an upper measurement head to be positioned above the sample in said receiver, and a lower measurement head to be positioned below the sample in said receiver;
a light source for emission of light;
an evaluation station including a detector for evaluation of emission signals emitted by the sample;
first light guide means for passing light from said light source to said upper measurement head and from said upper measurement head to said detector;
second light guide means for passing light from said light source to said lower measurement head and from said lower measurement head to said detector; and
a change-over switch movable between a first position connecting said first light guide means to said light source and to said detector and a second position connecting said second light guide means to said light source and to said detector.

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.
