Benefits
- Eliminate the need for purchasing and changing out filters for wavelength optimization with a monochromator-based wavelength selection for UV-visible absorbance between 190 nm and 850 nm
- Read up to 6 wavelengths in endpoint or kinetic mode for 96-well plates, and perform spectral scans to determine wavelength peaks
- Measurement accuracy is increased due to narrow bandwidths that deliver increased and linearity over the widest range of assays, including DNA quantitation in the UV range
- Better experimental signal discrimination using narrow absorbance bandpass for superior peak resolution and increased accuracy
- Quickly quantify DNA, RNA, and protein samples as low as 2 µL with the SpectraDrop Micro-Volume Microplate
- Ability to monitor temperature-sensitive reactions with consistent temperature regulation from ambient to 45°C
- Correction for varying microplate well volumes and the elimination of standard curves based on PathCheck® Technology, the only temperature-independent pathlength correction method
- Thorough mixing of samples in microplate wells by user-programmable Automix feature
- Seamless automation coupling with the StakMax Stacker, Molecular Devices' own integrated microplate stacker designed exclusively for the SpectraMax Reader
