DaphniaToximeter II
Biological early warning system with daphnia and
computer-controlled video evaluation
The bbe DaphniaToximeter II observes daphnia (also known as water fleas
– Daphnia magna) under the influence of a continuous flow of sample
water and evaluates the occurrence of toxic substances using a sensitive
alarm analysis. A CCD-camera records the behaviour of the daphnia, which
are kept in a chamber fed with sample water (0.5-2 l/h). The live images
are evaluated by the internal PC and investigated for changes in the swimming
behaviour. Statistically significant changes in swimming behaviour
trigger an alarm in the instrument. The control and monitoring of the instrument
can also be carried out remotely.
