Kinetic Microplate Reader

The VMax® microplate reader was the first instrument to provide kinetic reading capability, permitting researchers to monitor and automatically analyze enzyme kinetics in a microplate. Since its introduction in 1987, the VMax reader has expanded the use of microplate readers beyond traditional immunoassays to include a variety of biochemical analyses.      
      
The VMax microplate reader provides kinetic reading capability, permitting researchers to monitor and automatically analyze enzyme kinetics in a microplate. Adapts to your assay design; positive or negative single- or dual-wavelength kinetics; endpoint assays with speed read capability AUTOmix ensures adequate mixing before and between readings of solid phase reactions, such as ELISA assays Onboard microprocessor calculates and reports the rate of reaction for each well Integrated instrument control and data analysis with SoftMax Pro for your Windows or Mac OS computer Measurement range from 400-750 nm; 0.000 to 4.000 OD.
