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 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 should be used. The RC-300 and RC-350 respiration cells are normally used in conjunction with a 1302 Oxygen Sensor and a 782 Dual-Channel Oxygen Meter (both purchased separately).
These respiration cells are for small volume measurements of oxygen uptake rate by microbial suspensions, cell suspensions, mitochondria or enzyme preparations.
