Absorbance Readers

Absorbance Readers

BioTek's absorbance readers provide total flexibility for many applications. From basic ELISA to high throughput detection, the absorbance readers offer tremendous functionality. The monochromator based instruments provide UV-VIS detection while the filter-based systems offer great performance and good value.

The Eon™ Microplate Spectrophotometer is the latest in BioTek’s line of high performance, high value microplate instruments. Eon’s optical system allows wavelength selection between 200 and 999 nm in as little as 1 nm increments. No filters required for a new assay - Eon has it covered. It’s easy to view the sample’s peak wavelengths - just run a quick spectral scan in the cuvette, or in a microplate well. Eon reads 6- to 384-well microplate formats, and offers an optional cuvette port. Eon offers BioTek’s innovative 4-Zone™ temperature control system and takes it up a notch to 65°C. The higher setpoint capability expands application possibilities without the need for other instrumentation. Eon comes with Gen5™ v 2.0 and is compatible with Take3™ Micro-Volume plates for 2 µL measurements, as well as BioCell™, and cuvette measurements. Eon is BioStack™ and 3rd party automation compatible.

Gen5 Data Analysis Software

BioTek’s new Gen5™ software offers a logical interface designed to easily flow from reading parameters, to plate layout, to powerful data reduction, and finally to flexible data output options. The results of this intuitive design, including the exclusive StepWise™ protocol and data reduction tools and the power of Gen5's data reduction, will be evident in increased laboratory efficiency.
