6 Electrode Respirometer

For use with the 928 6 channel oxygen system - for replicate respiration measurements of cell suspensions, microbial suspensions, mitochondria or enzyme preparations The respirometer consists of a sealed water both containing six respirometer cells located above a six-position magnetic stirrer. Electrode holders, with a hole in their tips through which the membrane of the 1302 electrode protrudes, make a sliding fit into the cells. As the holder is inserted into the preparation, the sloping face at its tip gathers the air into the slot, which runs the complete length of the holder. Respiratory inhibitors or other solutions can be injected directly into the cell via this slot, using a fine bore needle (included). The volume of the cells may be set between 1 and 3 ml, by rotating the knurled collar of the holders. The rear of the bath contains a further 6 cells which are used to park the electrode holders and maintain them at a constant temperature while changing the contents of the respiratory cells. For easy removal and cleaning the cells are sealed into the water bath by O-rings.
