Reader, Microplate; Bio-Tek; Model: FLx800T; Fluorescence; w/ top probe only, standard w/2 excitation and 2 emission filters, Reads 6- to 384-well plate; 16 L x 15-1/2 W x 9 in. H; Includes Gen5RC reader control software

  • All models read 6-, 12-, 24-, 48-, 96-, and 384-well plates
  • Onboard software stores 55 programmable protocols, up to 75 custom programs, and eight microplate assay results
  • Two-line, 24-character LCD and menu-driven software simplify operation and programming
  • Onboard diagnostic testing utilizes three methods — an optical self-test, a universal test plate, and a “wet test” — to check instrument performance and optical specifications, and provides either soft or hardcopy results
  • Fiber-optic probes provide excellent sensitivity over a wide range
  • All units feature convenient front-panel access to accessories

Software Features

  • Includes Gen5RC reader control software or Gen5 Data Analysis software (model dependent)
  • Onboard data analysis provides curve-fitting options, including linear regression, polynomial, point-to-point, cubic spline, and four-parameter logistic curve fits

Model Features

  • Top probe is ideal for reading solid black plates
  • Bottom probe reads covered plates
  • Combination of top and bottom probes offers the most flexibility and includes automated probe switching for added convenience
  • Extended-range photomultiplier tube (PMT) extends emission range to 800nm Shaking and incubation options are ideal for temperature-sensitive assays
  • Single reagent injector is suitable for ion-uptake assays and flash luminescence

Supplied filters can be exchanged for other filters at time of purchase at no extra cost so that you can configure the unit to meet your specific application
