摘要:
A combined fermenter and measuring tube for NMR throughflow spectroscopy on cell suspensions in which the measurement tube has a capacity of 3 to 20 ml in the measuring zone of the magnet and a fermenter is a premagnetization reservoir of greater cross section of a capacity of at least 100 ml in the repolarization range. A liquid circulator is provided to provide a throughflow rate of 5 to 250 ml/s in the measuring tube.
