The device is based on a commercial instrument (BioLogic, SFM-400) with four stepper motor driven syringes and three mixers. A home-made SAXS/WAXS flow-through capillary cell (diameter ~1.6 mm) is adapted to the mixing chamber. The flow can be stopped with millisecond accuracy using a solenoid driven hard-stop. The dead time of mixing is about 2 ms for flow rates exceeding 7 ml/sec. This device can also be used to effect a temperature jump over the range 5 - 70 °C with a few millisecond deadtime.
