Strathkelvin - Model RC650 -Respirometer

For small volume replicate respiration measurements of oxygen uptake by microbial and cells suspensions, mitochondria or enzyme preparations. The respirometer comprises a sealed water bath containing six respirometer cells located above a six-position magnetic stirrer. A black acetal electrode holder, with a 5mm hole in its tip through which the membrane of the SI130 electrode protrudes, makes a sliding fit into the precision bore cell. 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 introduced directly into the cell via this slot, using a fine bore needle with luer fitting, which is supplied. The volume of the cell may be set between 1 and 3 ml, by rotating the knurled collar of the holder.
