The DFW-20 and DFW-20C/21C are highly sensitive fixed wavelength detectors for UV-Vis operation with prices starting at under $1,300.00. All fixed wavelength detectors come standard with the analytical flowcell. The DFW-20 cannot be upgraded to any other wavelength. If there is any intention to upgrade from a 254nm lamp to a 280, 365, 420, and 505nm lamp or any other lamp/filter combination, then the DFW-20C should be ordered. The DFW-21C comes standard with a 280nm phosphor coated lamp and filter. Other wavelengths kits such as 365, 420, and 505 are available as additional cost accessories.
This detector is ideal for routine analysis and monitoring of constituents in many applications. Its lightweight and very small footprint make the instrument perfect for procedures calling for chromatography in cramped spaces such as laboratory hoods.
The DFW-20 and the DFW-20C/21C can be used for both HPLC, low-pressure chromatography, with the semi-prep flowcell, and non-chromatographic techniques. The specifications on these series of instruments are equivalent to instruments twice its price. The unit has eight absorbance ranges for use with strip chart recorders, an autozero function, and provides a 10mV output for recorders and a 1V/AU output for data systems and integrators.
