The measurement chamber for earthworm experiments is used in neurophysiological experiments on intact worms. This involves stimulation of the worm by electrical or tactile means and measurement of its action potential. Worms remain uninjured and can be returned to their habitat after the completion of the experiment.

A cover with holes drilled in it allows worms to be secured transversely across the apparatus without difficulty and two replaceable longitudinal securing mechanisms prevent them from moving along. Contact with the worms is via a long line of electrodes which can be connected to the bio-amplifier via 2-mm sockets and special cables or to the stimulus generator of the biomeasurement interface. Tactile stimuli can be provoked through the hole in the cover. The measurement chamber can be quickly and easily dismantled after the completion of the experiments.
