ELx808 Absorbance Reader


The ELx808™ Absorbance Microplate Reader offers proven performance for many applications, from endpoint to fast kinetic protocols. The ELx808 is widely recognized as offering the industry-leading 4-Zone™ temperature control, which optimizes conditions for even the most temperature sensitive assays. Its high quality optical design ensures excellent precision, accuracy and linearity. Gen5 Software controls the ELx808 for easy data capture and powerful analysis.


4-Zone incubation

Unique heated track and carrier design minimizes evaporation and edge effect. Proven design is optimal for temperature sensitive applications like endotoxin analysis.

Fast kinetics, plus endpoint and linear well scanning

With measurements as fast as 6 seconds, ELx808 is ideal for fast kinetic assays. Linear well scanning collects multiple data points across the well for applications such as agglutination studies.

Optical design eliminates crosstalk

The multi-channel, staggered optics design of the ELx808 virtually eliminates channel-to-channel crosstalk.

Extensive data analysis with available Gen5 Microplate Reader and Imager Software

For data collection and powerful quantitative and qualitative analysis, the available Gen5 software offers intuitive protocol creation and flexible reporting and exporting functions.
