Begin your brilliant projects quickly, and then go even faster, with rapid UV-Vis absorbance reads for a variety of sample formats
Get absorbance measurements from 190 to 1000 nm quickly for samples in test tubes, cuvettes, and 96- or 384-well microplates. The SpectraMax® Plus 384 Microplate Reader gives you walk-up convenience for both standard spectrophotometer and microplate reader applications on the same instrument. Monochromator wavelength selection saves you the time and trouble of ever having to change out filters. Typical applications for this powerful reader include DNA and RNA quantification, enzyme kinetic assays, and ELISA based assays. When your project is ready for high throughput, take advantage of StakMax® automated microplate handling compatibility for full robotic integration.- Overview
