Mitocell Miniature Respirometer

This new Mitocell Miniature Respirometer has a chamber volume of only 50 µl and was introduced for measurements on mitochondria isolated from biopsy samples. It can be used in any situation where sample size is limited. The base section contains an integral solid state, fixed speed magnetic stirrer. The 1302 microcathode electrode (BS4 69-3006) is inserted from beneath the unit, and its projecting tip forms the base of the respirometer chamber. The glass chamber unit is surrounded by a water jacket through which constant temperature water is circulated. The respiration cell has a polycarbonate plunger with a central capillary through which solutions may be added during the course of a respiration run. Stainless steel magnetic spinbars are supplied together with a special 1 µl syringe supplied with MT200 and a 5 µl syringe with the MT200A for solution additions. An alternative version with a large volume (0.3, 0.5 and 1.0 ml) and a PTFE coated stirbar is also available.
