is OEM built-in UV detector suited for preparative and flash chromatography with diode array (DAD) in range 200 - 600 nm. It is offered in the following versions: Two Channel version measures at two wavelengths simultaneously with possibility to see current scan. Four Channel version measures at four wavelengths simultaneously with possibility to see current scan. Scanning version measures at four wavelengths simultaneously or sends scan with speed up to 20 Hz which allows to create 3D picture. More wavelengths or scan are used in liquid chromatography to verify purity of analyzed samples or in situations when some peaks absorb on different wavelengths. The unit is supplied with AMY17 PCB board of dimensions 100 x 160 mm (3.94 x 6.30 in) . It powers the lamps and control the unit.
