Photofluorometer

Model HV-EXP4036
Designed for use in routine or research work in;various application-medicine, Agriculture, Industry and others. An accurate and sensitive instrument, it can be operated without special skill of training. Fluorescence is basically the instantaneous emmission ;of light from a;molecule ( or atom) which has absorbed light. When a solution containing has molecules of interest is irradiated with light of a selected wavelength.;The radiation is given off at all angles but is usually collected at right angles to the primary light beam to reduce the efforts of scatter from the sample.;This energy is passed through a narrow bandpass filter and allowed to fall on a sensitive photodetector. The electrical output of the photodetector is amplified and fed into a moving coil meter. Calibration is performed on a;comparative basis against standards of known concentration,;(Details specification on request).
