If you’re choosing an absorbance microplate reader, one important feature to evaluate is the light source. While both LED and halogen light sources can accurately perform routine absorbance assays, LED-based optics offer several practical advantages for many laboratories, including longer operating life, reduced maintenance, lower heat generation, and fewer workflow interruptions. For routine applications such The post LED vs. Halogen Light Sources in Microplate Readers: Why It Matters for Routine Absorbance Assays appeared first on Life in the Lab .
