Stopped Flow

RSP-2000 is an advanced stop-flow system. Has more than 35 years of experience in the market. It can perform fast multi-channel detection. Up to 8000 absorption spectra were measured at the shortest interval of 1 millisecond.

Monochromatic detection of photomultiplier tubes is provided as a standard

Standard configurations include:

Light source, stop-flow mixer with automatic cock, spectrometer data processor, multi-channel detector, photomultiplier tube and optical guide software can help you get the best data through the simplest operation, and calculate the reaction speed on the same display screen.

Laser fluorescence measurement and flow flash measurement can be provided according to customer requirements.
