Usage: HM L-SP-UV series UV & visible spectrophotometer is routinely used in analytical chemistry for the quantitative determination of different analytes. It is used to identify drug, also for purity and assay determination.

Features: Particular optical system, high-performance holographic grating and receiver, ensure excellent performance index of the apparatus. Automatic adjustment with 0% T and 100% T, it is more convenient to set wavelength by hand. It has a parallel printing port, connecting with the printer directly to print data. Excellent system functions, it can control the switch of deuterium lamp and tungsten lamp alone. It also can achieve automatic calibration with wavelength and dark current, improving accuracy of tests.
