Measurement of reaction rate at 200 s⁻¹: Stop-flow measurement accessory

Combine with existing spectrophotometers to enable stopped-flow measurements! The RX2000 from Applied Photophysics is a high-performance stopped-flow measurement accessory. By combining it with existing UV-Vis spectrophotometers, fluorometers, and circular dichroism dispersers, it allows for the measurement of reactions that are over 1000 times faster compared to manual operations. With a dead time of just 8 milliseconds, the RX2000 can accommodate primary reaction rates exceeding 200 s^-1. ■ Adds stopped-flow measurement capabilities to existing UV-Vis spectrophotometers and fluorometers ■ Sample temperature control mechanism with a digital temperature display ■ Excellent dead time of 8 milliseconds allows for the measurement of reaction rates exceeding 200 s^-1 ■ Stable measurements enabled by gas pressure-driven accessories (optional) *Please feel free to contact us for more details.*

The SX20 stop-flow device from Applied Photophysics is used to study the transient steady states of fast liquid-phase chemical and biochemical reactions initiated by the rapid mixing and stopping (stop-flow) of reactants. Spectroscopic probes such as absorbance and fluorescence are employed to observe the progress of the reaction by recording changes in the intensity of the spectral signal as a function of time. The general upper limit of reaction rates measurable by stop-flow spectroscopy is approximately 2000 s⁻¹. However, by utilizing the small volume cells adopted by the SX20, it becomes possible to measure reaction rates exceeding 3000 s⁻¹. 【Key Features】 ■ Minimizes sample consumption with extremely excellent micro-volume performance and outstanding sensitivity ■ Capable of tracking reaction rates exceeding 3000 s⁻¹ with a dead time of less than 500 microseconds ■ Optimized for absorbance and fluorescence applications without the need for system reconfiguration ■ Powerful and user-friendly measurement, plotting, and analysis software *Please feel free to contact us for more details.
