Compact, versatile, and sensitive unit features easy to use menu driven software designed to step the operator through quantitative analysis. An extensive selection of easy to install Excitation and Emission Filters allows configuration of the unit to meet various applications. Software includes a Filter Selection Help Guide and a diagnostic menu for operation status checks. Sample concentrations are calculated based upon linear regression analysis of standard curve data. Stores multi-point (2 to 9 point) standard curves; and up to 9 multi-point standard curves. Measures single point raw fluorescence. Features discrete signal averaging. Automatic gain adjustment eliminates time consuming manual adjustment. Automatic optimization of linear range maximizes working concentration range. Large, versatile sample compartment and ergonomic design facilitates repetitive quantitative analysis of multiple samples. RS-232 serial interface for data output to printer or computer. All units supplied with one 360 nm Narrow Band filter and one 415 nm SharpCut filter. Additional narrow band and sharpcut filters for applications requiring excitation or emission wavelengths outside the ranges provided by the included filters may be purchased separately. All units are UL and CSA Listed. 230 VAC units are also CE Listed.
