Fluorescence Spectrophotometer LFS-A12

Fluorescence Spectrophotometer LFS-A12 consist of a high quality 150 W Xenon light source and photoelectric multiplier tube detectors for providing sufficient light intensity signal to detect sensitivity which ranges between 200 nm to 900 nm. Features fluorescence detection limit of ≤ 1×10-10 g/ml and Water Raman peak of S/N ≥ 150. It consists of the following characteristics, namely, high detection sensitivity, fast scanning speed, high dynamic range, fast 3D scanning, etc. The main principles includes measurement of absorption and fluorescence. Absorbance measurements can be taken via one or more wavelengths. The fluorescence unit increases the measuring range by 1000 for detecting DNA.
