Model No. SPE-0003 · Analytical Instruments
双光束扫描紫外可见分光光度计
Method validation and pharmacopoeia testing demand stable baselines and very low stray light, which is what this double-beam scanning unit is built for. Six selectable bandwidths from 0.1 to 5 nm, a photometric range of −4 to 4 A and stray light ≤0.01 %T at 220 nm let one instrument cover assays, filter characterisation and thermostatted kinetics.
