Molecular Devices VersaMax Microplate Reader
The Molecular Devices VersaMax ELISA Microplate Reader enables precise and accurate detection at wavelengths in the visible spectrum without the use of filters, providing consequence-free assay flexibility. The Versamax Microplate Reader is built around a grating monochromator. The VersaMax Absorbance Microplate Reader allows for selection of up to two wavelengths at a time for absorbance detection in the visible wavelength range (340 nm - 850 nm). Narrow bandwidths deliver increased accuracy and enhanced peak resolution. Temperature sensitive samples and reactions are kept safe with consistent temperature regulation from ambient to 45C. Mix samples thoroughly in microplate wells with user-programmable Automix feature.
All of our equipment is fully tested to perform at factory specifications before being shipped.
