The FLx800 is designed to combine excellent specifications and performance with convenience and ease of use. This design incorporates powerful performance at a price much lower than traditional fluorescence microplate readers. The FLx800 line includes several models with options that meet the specific needs of research and OEM users, including the ability to read multiple plate types and PCR tubes. New models in the FLx800 family include a reagent dispenser module. This new external dispenser module contains a precision syringe designed to deliver reagents directly into the wells of a 6-, 12-, 24-, 48- or 96-well microplate. The injector position can be optimized for detection from the top or bottom of the microplate for increased application flexibility. The injector model increases the range of applications available, including important calcium updatake reactions, and expands the range of high sensitivity microplate fluorescence instrumentation offered by BioTek.
