ECOM spol. s r.o. - Model TOY20DAD800 L -Scanning UV Detector

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.
