Bio-Rad Model 550, Ultramark, and Benchmark Microplate Reader Accessories - Manual (Page 4)

Section 1
Introduction
The Model 550 Microplate Reader is an eight-channel, vertical pathlength photometer
that measures the absorbance of the contents of the wells of 96-well microtitration plates. It
can perform single or dual wavelength measurements, and can report absorbance values to
three decimal places.
The Model 550 reader can be programmed by entering commands through the membrane
keypad to define assay blanks, select assay filter(s), set analysis parameters, and select report
types. Six different reports can be generated: Raw Data, Absorbance, Limit, Matrix, Cutoff,
and Concentration. Hard copy is produced by an on-board thermal printer.
The Model 550 reader features a built-in RS-232 serial interface device for convenient
computer interfacing. The Microplate Manager ® software for the Apple Macintosh ® , Power
Macintosh ® , or IBM-compatible series of personal computers offers a complete analysis pro-
gram (catalog numbers 170-6800 and 170-6617, respectively).
