Introducing the ELx800 Absorbance Microplate
Reader
The ELx800™ Absorbance Microplate Reader is a single-channel reader-assay system,
designed to automatically perform endpoint analysis for a variety of ELISA-based
applications. The reader can measure the optical density of solutions in 6-, 12-, 24-, 48-,
or 96-well microplates. The “NB” reader models can measure 384-well microplates and
60-, 72-, 96-well Terasaki trays as well as 6-, 12, 24-, 48-, or 96-well plates. The reader
features superior optical specifications, with an extended dynamic range of up to 3.000
absorbance units in some read modes. The wavelength range is from 400 nm to 750
nm. “UV” instruments have an extended range from 340 nm to 750 nm. Kinetic
analysis can be performed using computer control (e.g., via Gen5™, KC4™ , or
KCjunior™ running on a host PC).
Assay definitions (consisting of protocols, templates and formulas) and the data they
produce are managed by an onboard processor, via a 2-line x 24-character LCD screen
and membrane switch. Data can be stored onboard, printed, and/or uploaded to
controlling software on a host PC. The ELx800 is designed to serve as a stand-alone
system, or as part of a larger laboratory data network, sending, receiving, and
manipulating assay data as needed.
The ELx800 is backed by a superior support staff. If the ELx800 ever fails to work
perfectly, please call the Technical Assistance Center, or visit BioTek’s Web site. Refer
