Microplate Reader, Biorad 3550, Refurbished
TThe Model 3550 Microplate Readeri s a vertical pathlength photometer which measures the absorbance of the contents of the wells of a 96 well microtitration plate. Single or dual wavelength measurements can be made and absorbance values are measured to three decimal places
The Model 3550 Microplate Readeri s a vertical pathlength photometer which measures the absorbance of the contents of the wells of a 96 well microtitration plate. Single or dual wavelength measurements can be made and absorbance values are measured to three decimal places.
The 3550 Microplate Reader can be programmed by entering commands through the membrane keypad to select analysis parameters define plate formats and select report types and print options. Four different reports can be generated, absorbance, limit, matrix, and evaluation (which includes extrapolation of sample concentrations from a linear regression of standard values). Analysis parameters, plate formats, and reports which include an 8 x 12 presentation of data can be viewed on the liquid crystal display (LCD). The instrument’s memory has the capacity to store 9 analysis protocols, 9 formats, and 25 sets of plate data. For hard copy, the Model 3550 Microplate Reader can be interfaced with an optional printer such as the EpsonF X 850 (catalogn umber 125-1155)o r EpsonE X 800 (catalogn umber1 25-1230).
An optional plate stacker and loading mechanism with 25 plate capacity (catalog number 170-6612) is available for laboratories requiring high through put. The Model 3550 Microplate Reader includes a built-in RS-232-C serial interface for convenient computer interfacing with the Microplare Manager and Kinetic Collector software for the IBM PC or Apple Mac computer, which offer complete analysis programs
