Eine Apparatur zur kontinuierlichen Respirationsmessung an marinen Organismen

Measurements were made with a Clark electrode in a closed system under conditions of different, regulatable water current velocities. Six simultaneous parallel measurements are possible with only one electrode. The volume of respiration chambers amounts to 80 ml for small animals and 300 ml for larger ones. Technical details of the apparatus and measuring procedures are described. The accuracy amounts to 0.5 μl O₂ for the 80 ml chamber, and 2 μl O₂ for the 300 ml chambers. The apparatus has been successfully used on various marine evertebrates and algae.
