The FlexStation® 3 Multi-Mode Microplate Reader measures absorbance, fluorescence intensity, fluorescence polarization, luminescence, and time-resolved fluorescence. Programmable liquid handling Automated pipetting ensures consistent performance over multiple assay conditions on a microplate.
The FlexStation® 3 Multi-Mode Microplate Reader measures absorbance, fluorescence intensity, fluorescence polarization, luminescence, and time-resolved fluorescence. Programmable liquid handling allows for perfectly timed, automated biochemical and cell-based assays. The reader adds up to three transfers of assay reagents from a 96- or 384-well source plate to enhance assay design using integrated fluidics.
Onboard pipettor -
Integrated 8-channel or 16-channel pipettor increases assay flexibility by transferring reagents from 96 or 384 distinct wells in a source plate to the read plate.
Optimal assay excitation -
Dual monochromators allow users to target the optimal assay excitation and emission wavelengths and eliminate the need to change expensive band pass filters between experiments.
Low volume applications -
SpectraDrop™ Micro-Volume Microplate offers a high-throughput solution for low volume measurement, accelerating sample preparation time and increased productivity in DNA, RNA and protein research.
Robot integration -
The FlexStation 3 reader can be integrated with all leading partner robots and with our out-of-the-box automation solution for savings on up-front integration time and resources.
Other features and benefits include: - - Enable more assay conditions
- Automate pipetting
- Validate your reader
