Cell Culture Optical DensityThe Halo DNAmaster also measures bacterial cell density at600nm. Absorbance readings of approximately 0.4units definea bacterial culture in exponential growth phase and at themost appropriate for harvest or induction.Conventional SpectrophotometryAt the touch of the screen the Halo DNAmaster converts intoa conventional spectrophotometer for use with either theUltramicro cell or a standard 10mm optical path length quartzor glass cuvette. It can perform single wavelength photometryin either absorbance or % transmittance mode includingmultiple wavelength photometry for up to 6 user definedwavelengths in absorbance mode.Other functions include wavelength scans, time scans forkinetic studies and concentration calculations from standardcurves.Validation FunctionsTo ensure optimum instrument performance, a self-diagnosticfunction incorporating a number of parameters is executedeach time the Halo DNAmaster is switched on including aselectable GLP/GMP function.(Validation kit is required in some parameter.)17
