Product Description

The VMax Kinetic ELISA Microplate Reader Extends the durable filter-based absorbance measurements of the EMax Endpoint ELISA Microplate Reader to kinetic assays.

The VMax® Kinetic ELISA Microplate Reader the first of its kind for monitoring reactions over time opened the door to enzyme assays and continues to be the workhorse of the laboratory environment. Based on a rugged simple design the VMax Absorbance Microplate Reader offers a mean time between failure (MTBF) of 20000 hours with 97 independent and stationary fiber optics so that the microplate remains stationary during the entire reading cycle reducing the number of moving parts that can wear and need replacement.

Through sequential single-well illumination 100% of the available light is directed to each well through the optical fibers to achieve linearity to higher optical densities (ODs) and optimal signal-to-noise ratios. At 5 seconds to read a 96-well endpoint assay or a 5 second minimum interval between kinetic reads the VMax Microplate Reader has both speed and performance.

The VMax Microplate Reader is capable of reading up to two wavelengths at a time in the visible wavelength spectrum (400nm-750nm) with 4 filter choices included at time of purchase. Additional high-quality filters to supplement your assay wavelength range requirements are available directly from Molecular Devices.

VMax Microplate Readers can be operated as a stand-alone instrument and is also supplied with Data Acquistion & Analysis Software Molecular Devices' industry leading all-in-one data acquisition and analysis software.
