Usage: Molecules containing π-electrons or non-bonding electrons (n-electrons) can absorb the energy in the form of ultraviolet or visible light to excite these electrons to higher anti-bonding molecular orbitals. HM L-SP-V series Visible Spectrophotometer is routinely used in analytical chemistry for the quantitative determination of different analytes.

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.
