A powerful, affordable catalyst for scientific accomplishment
Make the most of your budget with the VersaMax™ ELISA Microplate Reader, our affordable, visible spectrum absorbance reader for 96-well microplates. This richly featured reader gives you the speed, convenience, and economy of monochromator-based wavelength selection for visible absorbance measurements between 340 nm and 850 nm, so you can accomplish more, with less.- Overview
- Applications
- Software
- Specifications
- Resources
- Eliminate the need for purchasing and changing out filters for wavelength optimization with a monochromator-based wavelength selection for visible absorbance between 340 nm and 850 nm
- Read up to 2 wavelengths in endpoint or kinetic mode for 96-well plates
