Respiration Cells

These respiration cells are for small volume measurements of oxygen uptake rate by microbial suspensions, cell suspensions, mitochondria or enzyme preparations. The electrode holder (supplied with the cell) slides into one of two glass tubes fused into the glass water jacket. The second tube is used to park the electrode holder when changing solutions. A fine slot (1 x 1 mm) in the side of the holder allows air to escape when the holder is inserted into the cell. It may also be used to introduce other solutions during the course of a respiration run and a fine bore needle with luer fitting (included). A PTFE covered magnetic spinbar is provided and the cell should be located on a magnetic stirrer unit (not provided). For fast reactions, it is recommended that FEP membranes used with electrode jacket (69-3011) are used.
