• Optical design eliminates crosstalk
• Extensive data analysis with available Gen5 Microplate Reader and Imager Software

BioTek ELx808 Details

Superior 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

Wavelength scanning, endpoint, and kinetics
Epoch is affordable, but far from basic! Perform spectral scanning, endpoint and kinetic assays in this simple to operate, simple to program microplate reader spectrophotometer and Gen5 software

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.
