Monochromator-based Spectrophotometer

The SPECTRAmax 340PC384 offers everything needed to measure absorbance in the visible range, including temperature control, robotics-compatible interface and SOFTmax® PRO data analysis software. Each well has its own sample beam and reference detector. The eight-channel system, consisting of eight sample beams and eight reference beams, delivers both precision and speed of reading across the microplate. The unit has a monochromator instead of interference filters. Select the absorbance maximum of a sample and let the monochromator tune to that exact wavelength. Or scan up to 384 wells at any time to determine the best assay conditions. The wavelength and scanning ranges are from 340-850 nm in 1 nm increments. PathCheck® sensor measures the depth of the liquid in each microplate well. This information can be used to normalize absorbance values to a 1 cm pathlength.
