Plate Readers Manufacturers

The majority of plate readers are based on single point detection using photo-multiplier tubes. Typically the plate moves under the detector, with the latter located in a fixed position. Most readers use a white light source such as a tungsten lamp or more commonly a xenon flash lamp. Some plate readers use light-emitting diodes to provide a cheap source of intense light at a specific wavelength. It generally offers higher sensitivity, a wider dynamic range and lower cost relative to plate imagers.
